Abstract
Immediate estimation of compressive strength of concrete at the standard curing age of concrete of 28 days being not affected by the weathering of cement used in the concrete is carried out by the addition of an alkali hydroxide as well as a setting accelerator to the mortar portion obtained by wet screening of fresh concrete.
