SPECIAL FOCUS: CONCRETE & CONCRETE EQUIPMENT recycling concept for concrete!” using some form of 3D concrete printing during years.With precast, logistics needs In some countries where they have too and will continue to use it in the future, are minimal. Precast foors, walls, frames much slurry, they also employ a method expanding on the practice as technology and foundations are transported to a called flter press where they flter the excess becomes less expensive and its uses grow. construction site ready-to-install. Logistics cement particles out and reuse the water.So, As more places around the world begin to to building site is arranged with just one with this system, you not only eliminate the urbanize and industrialize, the demand delivery vehicle instead of several raw problem of efuents, but also save precious to build a wide variety of structures will material transfers back and forth. resources like water and other raw materials. increase.Asia Pacifc region will lead the way Looking at the bullish market potential, Also as manpower becomes more expensive, in 3D concrete printing with China being, Schwing Stetter will be launching precast reliance on machines like these will be more perhaps unsurprisingly, the fastest growing equipment through an acquisition or a proftable in the future. Because they are not country in terms of its use of 3D printing manufacturing license or a joint venture to only more efcient and safe, they also waste with concrete. cater to the growing precast construction less and pollute less. market. Te company currently has a revenue Companies like Ultratech, Lafarge have Precast concrete of around `1,200 crore and expects a better already been setting up concrete recycling Precast concrete is a smart way to build any growth over next couple of years, as the road plants at their RMC plants for some time type of buildings, safely and afordably. construction industry has started growing now. Others like JK Lakshmi are following Originally developed in the Nordic again, said Anand Sundaresan, chairman, suit. Also, all green building ratings countries, modular precast is one of the Schwing Stetter Sales & Services. especially Leed platinum ratings now insist world’s most common and resource-efcient on the installation of concrete recycling ways to build. It ensures fast construction Self consolidating concrete plants at the RMC plants. Gradually times, high profitability and excellent The global self consolidating concrete concrete manufacturers are beginning quality. Still, requirements for beautiful, (SCC) market is estimated to grow at a to understand both the ecological and modern buildings are not compromised. CAGR of 9.56 per cent by 2020. SCC, a economic benefits of concrete recycling Precast concrete is an industrialised way to high-performance high-fow construction plants. Typically, in two years, you can build. It means transfer of work from sites material, is manufactured just like expect to get back the entire return on your to factories. Tis improves productivity and traditional concrete, sans the addition of investment. quality and shortens construction time of a super-plasticizers and viscosity modifying building. In short, precast concrete lowers admixtures. The SCC was developed 3D printing concrete total construction costs considerably. around 25 years back, and has since been Currently, the market size for 3D concrete Precast also has lower lifetime costs than gaining popularity among the contractors printing sits at $24.5 million. According any other building solution. It is possible and architects in the developing countries, to the study, this is expected to grow to due to consistent high quality of industrially primarily for use in precast and repairing $56.4 million by 2021. Many construction produced products. Precast minimises e.g. applications. However, its usage has companies around the world are already structural and facade maintenance needs also increased in the new construction aPrIL 2017 |construction opportunities 81
