What We Do?
The rapid growth and development of urban centers call for shorter timelines of construction at a competitive cost by implementing proven technologies while ensuring high standards and uniformity in quality. These are thev needs of the hour which can be effectively met by Precast Prestressed Technology.
Precast and Prestressed concrete technology involves the Industrial process of casting structural & architectural concrete elements, effectively using pretensioned tendons in a stationary profile mold and long casting bed, under controlled environment and quality standards, cured, transported to the construction site and erected into place. Prestressing is a combination of concrete and high strength prestressing strands.
Prestressed tendons are used to provide a clamping load which produces a compressive stress that offsets the tensile stress that the concrete compression member would otherwise experience due to a bending load. Due to internal structural mechanics resulting from prestressing, prestressed concrete greatly enhances the structural resilience and load bearing capacity of precast elements. This technology enables production of longer span floorslabs viz., T Slabs, Hollow Core Slabs, Solid Slabs, etc., and beams at required depths, which is a limitation in traditional reinforced concrete methods. This technology is widely applied in Buildings, Metro Rail Projects, Tunnels, Bridges/Flyovers and Underpass construction. Precast Prestressed Concrete has emerged as a revolutionary technology and methodology in India recently, while it is well developed and has been under implementation for decades in Europe, GCC, and USA.
WHAT IS CLC BLOCK?
A type of lightweight concrete known as cellular light weight concrete (CLC) is created in the same way as regular concrete under natural production conditions. It is created by first creating a slurry of cement, fly ash, and water, which is then combined with pre-formed stable foam in a concrete mixer while the environment is still ambient. Either the mixture is poured into prefabricated moulds or blocks. Due to the ball bearing effect of the foam bubbles, the foam gives free flowing qualities to this slurry, allowing it to freely flow into all corners and compact by itself in the moulds without needing any type of vibration or compaction.
ADVANTAGES OF CLC BLOCKS CLC Blocks are competitive with bricks in pricing and offer significant savings for finished structures. Savings in construction cost can be as much as 18% when using CLC Blocks, as compared to brick, after taking into account the resulting savings in gravel, cement, steel, labour, Structure, foundation etc.
- Thermal Insulation: This increasingly takes the top spot when it comes to building design and construction. There are several expensive ways to insulate a sandwich wall structure by adding various rigid insulation materials. While these methods can produce satisfying results mathematically, they are not necessarily the best choices for safety, health, or the environment. The ideal option is to include thermal insulation in the concrete mix, like that found in CLC that has been air-cured.Foam concrete used in clc has a thermal conductivity of about 0.05-0.15 Kcal/mh, which is 20–30 times higher than regular concrete.
- Weight reduction: Because CLC Blocks are only 1/3 as heavy as traditional bricks, handling and shipment are simple.The building's structure will need less steel and RCC thanks to this lightweight material.
- Fire Resistant: Air-embedded in the CLC contributes to the CLC's high fire-rating and fire resistance. A wall that is 13–14 cm thick and with a density of 1200 kg/m3 can withstand fire for 5 hours. A 400 kg/m3 layer of CLC that is only 10 cm thick causes the same delay. Other than that, CLC is non-combustible.
- Work Execution: Unskilled labour is generally used and a minimum skilled staff is required.Because bricks are lightweight, they can be built in two and a half times as fast as cement blocks and clay bricks.
- Environmentally friendly: It doesn't waste resources or produce pollution.
