What is permissible value of depth of water penetration in normal concrete. How much this value could be reduce in Ultrafine concrete.
According to Indian Standards (IS 456:2000), the maximum depth of water penetration in typical concrete is 50mm after 72 hours of immersion.
Ultrafine concrete, also known as high-performance concrete, is created with the goal of having better features such as high strength, durability, and low permeability. As a result, as compared to regular concrete, the depth of water penetration in ultrafine concrete can be greatly reduced.
However, the amount to which the value may be lowered in ultrafine concrete will be determined by a variety of parameters such as mix design, curing conditions, and material quality. It is advised that the permitted depth of water penetration be determined by consulting the applicable ultrafine concrete standards and recommendations.
According to the Spanish structural code, depending on the exposure class, the maximum water penetration must be less than 50 mm.
