2020-6-7The standard consistency test of cement paste is used in the determination of watercement ratio for the initial setting time final setting time and soundness test of cement and compressive strength of cement. This actually helps you to decide how much water we should add to gain strength and chemical reaction to develop.

Read More >2010-10-7The strength of cement is determined by TS EN 196-1 in Turkey that is the same for all types of cements. However, American cement producers use different standards for testing the strength of Portland cement and blended cements. The main difference is the amount of water utilized in producing the cement mortar.

Read More >The test for compressive strength is generally carried out by crushing cubes of hardened cement-sand mortar in a compression machine. The compressive strength of the cubes is determined by the highest stress applied to a cube specimen that causes it to fracture.
Read More >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 ...
