Fosroc are the pioneers in providing a range of concrete admixtures, liquid additive, added to concrete to enhance the quality and properties of concrete in both the plastic and hardened stages, which eventually help in achieving the desired durability in concrete structures. Our products comply with IS 9103, IS 2645, ASTM C 494 BSEN 934-2, BS 5057. Types of Admixtures: On Monday 14th January 2019, the Polavaram Dam project in Andhra Pradesh entered the Guinness Book of World Records for pouring 32,315m3 of concrete in 24-hour period. Fosroc, as the official supplier of admixture for the event, dispatched 100MT of Conplast SP430 on time to help set the world record. View the Polavaram Dam project video. Water is the first and foremost consumed substance in the world. Construction industry consumes the highest water for production of concrete and for curing. Concrete is the second most used commodity after water. Fosroc concrete admixtures can reduce the use of water up to 40% and at the same time improves the properties of concrete and enhance durability.

Pavement quality concrete in road laying require high compaction designed specifically for achieving the desired flexural strength. It is essential that the concrete is able to support itself in the shape moulded for PQC applications with very low slump.
Product Range - Auramix 300, Auramix 350 PQC and Conplast SP430 ITPQ.
In critical applications such as in diaphragm/ retaining walls, basements, roofs and roofs overlays, wet areas and water retaining structure, casting waterproofed concrete is of utmost importance to achieve water resistance.
Product range - Conplast WL Xtra, Conplast WP90 and Conplast Crystalline.
For highly congested reinforcement in columns, beams and rafts, where regular concrete placement is not possible, free-flow, self-compacting concrete (SCC) is designed so that there is no need of any vibrators. Special admixtures for SCC prevent any segregation or bleeding although fine contents which occur high during concreting.
Product range - Auramix 400, Auramix V200 and Auramix 300 Plus.
Concrete poured in shear walls and retaining walls must have high slump retention while being cohesive to give a firm finish.
Product range - Auramix 300 Plus and Auramix 450.
Concrete pours in dams needs low slump while effectively avoiding cold joints between each pour. For such specific needs, our air entraining and retarding plasticisers are ideal.
Product range - Conplast R, Conplast AEA and Conplast PA21S.
Concrete for precast railway sleepers, Paver blocks, masonry bricks, and aerated concrete blocks, have different mix designs and workability requirements. Our range of admixtures are designed to meet the various requirements of these industry.
Product range - Auracast 50, Conplast SD110, Conplast F297 and Conplast NC.
The New Austrian Tunnel Method (NATM) uses the geological stress of the surrounding mass to stabilize the tunnel itself. The excavation is immediately protected with a layer of sprayed concrete (wet) with accelerators that enable quick setting properties to provide an Initial Setting Time (IST) as low as 5 minutes. Fosroc’s range of accelerating admixtures are used for fast setting of concrete and to attain the required slump and pumpability.
Product range - Sprayset HBL, Sprayset HBLM, Sprayset HBP, Sprayset SL, Conplast SP430G8 and Auramix 300.
