Get PriceProperties of concrete - Wikipedia. In very high-strength concrete mixtures (greater than 70 MPa) the crushing strength of the aggregate can be a limiting factor to the ultimate compressive strength. In lean concretes (with a high water-cement ratio) the crushing strength of the aggregates is not so significant.

Get PriceIn order to produce concrete with a lower water-to-cement ratio, chemical admixtures can reduce the required amount of mixing water and still obtain the desired fresh properties to facilitate the placement and consolidation of the concrete. One of the key parameters in producing high-strength concrete is the use of a low w/c ratio.

Get PriceTo design a concrete mix of the desired strength with available materials, the strength of cement is required at 7 days (IRC:44-2008) 4 or at 28 days (IS:10262-1982) 5. Based on the strength values of cement, w/c ratio is directly read from the available charts given in IRC-44 & IS-10262.

Get PriceAccording to Wikipedia, Compressive Strength of concrete is defined as the Characteristic strength of 150mm size concrete cubes tested at 28 days. Why do we test at 7, 14 & 28 days?
