According 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? Concrete is a macro content with Sand, Cement, & Coarse aggregate as its micro-ingredient (Mix Ratio) and gains its strength over time at the hardened state.
Apr 08, 2014· under step:3,u have mentioned in the table that the standard deviation for design mix of the grades of concrete from M30 to M55 as 6,whereas the IS-456:2000 has specified the standard deviation 5 only for the above grades of concrete.please verify and correct the same.
The various factors affecting the mix design are: 1. Compressive strength It is one of the most important properties of concrete and influences many other describable properties of the hardened concrete. The mean compressive strength required at a specific age, usually 28 days, determines the nominal water-cement ratio of the mix. The other

Concrete Mix Design Calculation : M20, M25, M30, M40 Grade Concrete Concrete mix design is a procedure of selecting the suitable ingredients of concrete and their relative proportions with an objective to prepare concrete of certain minimum strength, desired workability and durability as economically (value engineered) as possible.
Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate.
