Specifying precast supports local businesses and communities. At the end of its life precast structures can be fully recycled. The stability of precast over its life delivers an environment free of fumes and chemicals. Ground works can commence while precast is being manufactured, just-in-time delivery eliminates double handling and subsequent trades can get in quicker. Saving time saves money, it is that simple. Precast requires almost no maintenance and can offer a substantial energy saving from its high thermal mass. Nor does it emit toxic fumes when exposed to fire. Nor will it be damaged if exposed to cyclone or flood. The design flexibility offered by precast can deliver award winning results. Shapes, colours and textures can all be designed to suit. Of course, when it comes to materials selection, different applications will require different materials. To find a National Precast member who can supply your next project, visit www. Too often sustainability is interpreted as benefiting the environment only. As well as meeting the needs of the environment, sustainability must also deliver benefits to the economy and the community. The clever design of Ultrafloor can give a modern industrial look to the inside of an office while reducing the amount of concrete used for a suspended floor.

Privacy Policies. Significant cost savings are realised through areas such as: Manufacture of precast elements concurrent with commencement of early site work. Expedited construction Reduce time on site Reduces site defects Reduces propping and scaffolding costs Lower site labour cost Reduce plant, amenities, tools and materials storage on site. Minimise finance cost resulting from reduced build time. Earlier revenue receipts because of shorter project times. Once precast installation starts, on-site construction and off-site manufacturing can be overlapped, thereby reducing overall site construction time. The continued, uninterrupted erection of precast structural components lends itself perfectly to fast track construction schedules. Installation incorporates the latest in connection technology, and can proceed swiftly and safely in almost any weather by expert erectors. Concrete curing time will not affect project time. Most precast products are trafficable after installation. Most precast products are accessible and trafficable providing safe access to the next part of the construction site. Less onsite labour Onsite trades, labour and their associated activities are minimised Fire resistant Most precast products are installed directly from the truck into position without the need for scaffolding Safety can be improved onsite with less workers, equipment and material reducing site congestion. Precast concrete allows increased accuracy and consistent placement of reinforcement when compared to insitu construction. The accurate placement of reinforcement in precast concrete provides the same level of durability with nominal covers mm less than are required with insitu construction. Precast offers the advantage of placing mature concrete into its in-service environment and loading. This benefit ensures that the concrete is at its best when exposed to aggressive loads. This is in comparison to insitu concrete which ages in the aggressive environment and is unable to immediately carry design loads. Insitu concrete therefore requires propping and time to age to avoid creep under design load at early age causing permanent deflection in the structure. Recycled supplementary cementitous materials such us fly ash and blast furnace slag, silica fume, recycle aggregates and grey water can be incorporated into precast concrete. This diverts materials from landfill, reducing use of virgin materials and the overall environmental burden. On site, precast construction reduces air pollution, noise and debris. Controlled management of waste with production of precast concrete. Tight control of quantities of constituent material and precise mix proportions mean optimum use of material. Standard precast building elements are manufactured in moulds that are re-used many times. Any waste materials are more readily recycled because production is in one location. Site waste is also reduced as only the finished elements are delivered to the construction site. Technical Info. Other Brands Within. Start typing and press Enter to search.

The many advantages of precast concrete are the driving forces behind this increase, including cost and time savings, better quality, and improved project site safety. An increased shift towards offsite construction and environmentally friendly construction projects are other factors behind the move toward the use of precast concrete elements. The use of ultra-high performance concrete UHPC for precast concrete construction overcomes these disadvantages. The use of a specific type of UHPC—Cor-Tuf UHPC—for precast concrete elements takes precasting to a new level, removing all obstacles and creating an end product that is virtually indestructible. We have written in the past about the many benefits of UHPC versus traditional concrete. Your team of workers can use the same equipment and follow the same processes they always have—but you get a highly superior product that is stronger and more durable. The use of Cor-Tuf UHPC for precast concrete structures also removes any and all worry about damage during the transportation and installation processes, delivering substantial critical-path savings to every project. Cor-Tuf UHPC is so strong and durable that your workers can install all day long without losing time repairing cracks or breaks or replacing entire precast elements. From cast-in-place joints between precast beams to connections between precast deck panels, Cor-Tuf UHPC creates a stronger bond than traditional concreteincreasing the lifespan of construction projects. Field-cast connections made with UHPC also require a smaller amount of material and can be completed more quickly, further adding to savings over the product life cycle. Another benefit of UHPC is that concrete wall panels made with this type of concrete require less material while still delivering more strength and are 25—33 percent thinner than those made from traditional concrete. The lighter weight makes these precast structures easier to move and install, increasing the safety of construction projects. We have conducted tests on both square and H-pilings made of Cor-Tuf UHPC, which have clearly demonstrated the amazing benefits of this revolutionary concrete material. Testing of square pilings have shown:. H-piling tests demonstrated the same abilities to withstand extreme compressive and flexural loads, while using only roughly half the amount of material. PSE specializes in precast, prestressed concrete for buildings, marine structures, and bridges using UHPC in components and connections. Iowa was the first state to build a bridge using UHPC inlargely because it is the state with the greatest number of deteriorating bridges. Deck panels made of traditional concrete are usually seven to eight inches thick when beams are in place and much thicker when beams are not used. UHPC is also nearly impenetrable to water and deicer, vastly increasing the lifespan of bridges. Iowa has 14 additional UHPC bridge projects in the pipeline, which are vital to rural farms that depend on bridges for their livelihood. Research being led by Iowa State University has shown that UHPC can be used strategically to extend the life of bridges through patchwork, and they are also investigating its use in building features and wind turbines. As we continue to make new advances in our proprietary UHPC mix, we are excited to see the other benefits it can bring to the concrete industry and global infrastructure. When it comes to precast concrete, we have no doubt that Cor-Tuf UHPC demolishes all other products in every category, from strength and durability to safety and critical-path savings. As we continue to complete more projects with our proprietary Ultra-High Performance Concrete mix design, we are thrilled to see that Cor-Tuf UHPC continues to meet and even exceed our expectations. At Cor-Tuf, we are committed to continuing to push the boundaries of what concrete can do. We have written in the past about some of the revolutionary uses for Ultra-High Performance Concrete UHPC in bridges, overlays, and other major infrastructure projects. June 3, Follow Us.

Environmental benefits of precast concrete
Here at Carlow Concrete Tanks, we provide precast concrete product and custom solutions for the agricultural, domestic and environmental market. But what exactly is precast concrete and what are the benefits of using it in your agricultural, domestic or environmental solutions? Precast concrete and normal concrete are two very different products with two very different uses. In contrast to normal concrete which is known as in situ concrete, precast concrete is designed and manufactured in a controlled factory environment using state-of-the-art manufacturing techniques. The moulds for precast concrete are reusable, reinforceable and adjustable. For example, our precast septic tanks are reinforced with steel to ensure the construction of a strong, durable system. The moulds are also set up for the design specifications before the concrete is poured in. When the concrete has been poured, it is then vibrated before undergoing any last finishes such as polishing or staining. The product is then transported to site and craned to its intended location. This is in contrast to standard in situ concrete which is poured into the formwork and cured onsite which is far more costly, labour intensive and time intensive. The unparalleled quality, affordability and durability of precast concrete allows it to stand out when compared to in situ concrete. Precast concrete can be used in numerous industries as it comes in various shapes and sizes which can be tailored to a number of different requirements. For example, here at Carlow Tanks we use precast concrete domestically for septic tanks but also in the agricultural industry for rainwater tanks. Using precast concrete helps to speed up the building process. Having the structures manufactured in a factory and delivered to the site; then hoisted up by crane into their desired location eliminates the need to wait for concrete to dry before work can proceed. The process of producing precast concrete is so efficient that precast materials can be made in advance and stored until needed on site which saves time and money and ensures your materials are ready when you are. As precast concrete is manufactured in a factory, all pre-checks and quality control checks can be conducted prior to being on-site. Saving time and reducing the risk of any quality-control issues only being discovered on the day a project is due to go ahead. As the environment in which precast concrete is manufactured in is controlled, this eliminates the chances of outside variables such as weather interfering with the quality or timeliness of production. This also means that the production and delivery will be on time as weather delays which occur with in situ concrete pouring are not an issue. Concrete is already an affordable material but the low cost manufacturing methods of precast concrete makes this concrete solution even more affordable. Although affordable, precast concrete is of extremely high quality and has extremely low maintenance costs. Precast concrete can almost always be broken down to be reused or recycled. Mouldings are also reusable and can be re-moulded time after time to produce various sizes and designs of precast concrete. Secondly, concrete itself is composed of natural aggregates including sand, gravel, water and rock. Much of the water used in the concrete making process is then recycled. Contact us today on to learn more about our precast concrete products and how they can benefit you. What is precast concrete and how is it different to normal concrete? What are the benefits of using precast concrete? Versatility Precast concrete can be used in numerous industries as it comes in various shapes and sizes which can be tailored to a number of different requirements.

Concrete is a very sustainable building material with regard to the energy consumption during its production and its characteristics during its useful life. Concrete consists of water, sand, gravel and cement. Water, sand and gravel naturally exist in our environment. For the production of cement, the raw materials limestone, clay, sand and iron ore are kilned, gypsum is added and afterwards the mixture is finely ground. At the production of precast concrete in the plant, the recycling of the fresh concrete which has not been used is a big priority. Fresh concrete is concrete which is not yet cured. Modern precast concrete plants are controlled and monitored by a master computer. The master computer exactly calculates the necessary amounts of cement, construction steel, water etc. Not only during the production of precast concrete elements are savings possible. The positive characteristics of the building material also take effect during the utilization of a precast concrete building. Very little waste is produced in the production process of precast concrete elements because all the materials are optimally used due to the computer-operated production. In addition to that, the amount of packaging material can be reduced because precast concrete elements are stored and transported to the building site without packaging. After the demolition of a precast concrete building, the concrete and the reinforcement can be recycled and used for the construction of a new building or for road construction. Precast concrete elements are absolutely safe for the construction of housing, any other building or in the field of water storage. Concrete does not dispense any harmful substances to the surrounding air or water. In addition to that, precast concrete elements can be used for the storage or transport of toxic substances because they cannot get out through the precast concrete elements. Solid building elements have a high thermal storage capacity. The low thermal conductivity of reinforced concrete causes a balance between extreme temperature changes, i. During the day the rooms are cool, thus reducing the cooling costs. This principle can also be applied in the other direction, when temperatures are low.

Environmental benefits of precast concrete
Precast concrete reduces the construction and installation time on your project, which lowers your total cost. Walls can be produced off-site while on-site preparation work is beginning. When the site is ready for installation, the system can be transported and immediately erected, which saves weeks of on-site form work and curing time. Precast walls can also integrate insulation, conduit and structural systems. This eliminates multiple products, processes and labor that add cost to a project. Precast is poured indoors, so your project will have no construction delays due to inclement weather—again, lowering your total costs. Precast allows designers to be innovative and attain design objectives that are not possible through traditional construction techniques. An unlimited number of form liners and admixtures allow precast concrete to have the appearance of a variety of building materials. These include brick, stone and other masonry products, and are much lower cost than traditional building materials. Brick or stone can also be placed in the mold prior to pouring concrete. Once the concrete has cured the material will be cast into the wall, eliminating extensive labor and delays on the job site. By choosing precast early in the design phase, designers can utilize the full benefits of precast concrete. Precast concrete products are developed in a controlled manufacturing environment, which produces the highest quality material possible. This proximity allows for ultimate material control and customization. Precast also has a high thermal mass, which minimizes energy consumption and costs for heating and cooling. Costly chemical cleaners are not needed for maintenance, which protects the environment while saving money. Optimum savings can be achieved when we work directly with design teams to develop the precast options for desired architectural finishes and structural requirements. This material creates high quality finishes and meets superior structural standards. Loudon, TN sales vanhooseco. Faster Construction. Efficient Design. Aesthetic Flexibility.
