Read MoreConcrete rated at 6000 psi or higher is considered highperformance concrete and is used for heavyduty commercial applications. Some specialty projects use 10000 psi concrete and two skyscrapers in Seattle Washington incorporate highperformance concrete rated at 19000 psi according to the Portland Cement Association.
Read MoreThe ratio of the water to cement is the chief factor for determining concrete strength. The lower the watercement ratio the higher is the compressive strength. The capacity of concrete is reported in psi pounds per sq. inch in US units and in MPa mega pascals in SI units.
Read More2019922 Concrete is a strong hard building material composed of sand and gravel and cement and water. It is used for making buildings roads bridges vessels pipes etc etc etc. As the concrete formulations develop concrete is increasing its range of applications such that it is making inroads into those presently monopolised by metals.
Read MoreGrading limits and maximum aggregate sie are specified because these properties affect the amount of aggregate used as well as cement and water requirements workability pumpability and durability of concrete. In general if the watercement ratio is chosen correctly a wide range in grading can be used without a major effect on strength.

Read MoreCement and water form a paste that coats each particle of stone and sandthe aggregates. Through a chemical reaction called hydration the cement paste hardens and gains strength. The quality of the paste determines the character of the concrete. The strength of the paste in turn depends on the ratio of water to cement.
Read MoreConcrete Mix Design As Per Indian Standard Code The nominal mixes of fixed cementaggregate ratio by volume vary widely in strength and may result in under or overrich mixes.

Read More201993 The reason you cant find a prescribed mix ratio for C40 is it doesnt exist. BS5328 only goes up to 25N and anything above 20N cant be mixed with all in ballast. Thats not to say you couldnt end up with a mix higher than 25N just that its not predictable based on the mix ratio. The only way to guarantee 40N is readymix.
