For instance, C10 has the strength of 10 newtons, C15 has the strength of 15 newtons, C20 has 20 newtons strength and so on. Different mixes (M) come in various mix proportions of the various ingredients of ... cube size is 150x150x150, because it has been set as standard size, the value of compressive strength of which has been standardized at 28 days.We can also use 200mm cube, but you have to convert the compressive strength of 200mm cube to the equivalent of 150mm cube to know the actual strength of the concrete.

Aug 11, 2018· When the aggregate is sieved through 4.75mm sieve, the aggregate retained is called coarse aggregate. Gravel, cobble and boulders come under this category. The maximum size aggregate used may be dependent upon some conditions. In general, 40mm size aggregate used for normal strengths and 20mm size is used for high strength concrete. High-strength concrete is specified where reduced weight is important or where architectural considerations call for small support elements. By carrying loads more efficiently than normal-strength concrete, high-strength concrete also reduces the total amount of material placed and lowers the overall cost of the structure.
