Compressive strength of concrete cube test provides an idea about all the characteristics of concrete.By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures.

Get Price28/10/2013· Specifying concrete strength is normally done with a minimum compressive strength (psi) at a certain age (days). Specified concrete compressive strength is the minimum compressive strength at which the concrete should fail in standard tests of 28-day-old concrete cylinders. A typical concrete compressive strength specification requires 4,000 to

Get PriceConcrete compressive strength does not depend on the full hydration of its cement particles but essentially on their closeness. 10,11 In a concrete having a water/cement ratio lower than 0.42, hydration stops when there is no more water to hydrate the cement particles. Below this critical value of 0.42, very fine cement particles can be fully hydrated but only the surface of the coarsest ones

Get PriceThe compressive strength of concrete is given in terms of the characteristic compressive strength of 150 mm size cubes tested at 28 days (fck). The characteristic strength is defined as the strength of the concrete below which not more than 5% of the test results are expected to fall.

Get PriceConcrete strength. Many factors influence the rate at which the strength of concrete increases after mixing. Some of these are discussed below. First, though a couple of definitions may be useful: The processes of 'setting' and 'hardening' are often confused: Setting is the stiffening of the concrete after it has been placed. A concrete can be 'set' in that it is no longer fluid, but it may
