EXPERIMENTAL STUDY ON INTERNAL CURING OF HIGH STRENGTH CONCRETE

Self - curing concrete is provided to absorb water from atmosphere and then release to concrete to achieve better hydration of cement which solves the problem of lowered cement hydration because of improper curing, and thus unsatisfactory properties of concrete. The present investigation involves the use of self - curing agent, Solid paraffin wax (SPW) melted at 70 o C of dosages ranging between 0.1 to 2% by weight of cement added to water along with Super - Plasticizer (Master Rheo - build). Comparative studies were carried out for Water retentivity, Compressive strength, Split Tensile strength and Flexural Strength tests after 28 days for convention al cured and self - cured concrete
