Jul 14, 2017· This makes it difficult to ascertain the exact compositions of the two phases. The cubic form generally contains 4% substitution of SiO 2, 5% substitution of Fe 2 O 3, and about 1% each of Na 2 O, K 2 O, and MgO. The orthorhombic form has similar levels, but with a greater (~5%) substitution of K 2 O. Also Read: How to Check Quality of Cement on Site? 4.

Dependence of compressive strength on mix parameters. The w/c is the single most important factor governing the strength of concrete. High w/c implies high porosity, and thus lowered strength. The trend shown in Figure 1 for the dependence of compressive strength on the w/c is true for most concretes.

Concrete 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 ...
