Plasticizers for Concrete: The Complete Guide to Benefits, Types, and Applications
ByN Lavanya Posted onNovember 25, 2023February 21, 2026 February 21, 2026
Plasticizers, or water-reducing admixtures, are chemical agents added to concrete mixes. They slash water content by 5-30% without losing workability or slump. This technique boosts compressive strength 20-50%, cuts permeability, and slashes cement needs by 10-15%—key for sustainable 2026 builds. Benefits: Higher durability against chemicals/frost. This allows for the use of self-compacting concrete (SCC) in complex forms….

As per IS 456-2000, what is the maximum free water to cement ratio of an M20 grade reinforced concrete under mild exposure conditions?
ByN Lavanya Posted onNovember 22, 2023
a) 0.50 b) 0.45 c) 0.60 d) 0.55 As per Cl. 8.2.2, Table 2 of IS 456:2000, the maximum free water-cement ratio is specified based on the exposure condition and concrete grade. For an ordinary reinforced concrete of M20 grade under mild exposure condition, this ratio should not exceed 0.55. Therefore, option d) 0.55 is…
