Abstract

Internal curing technology is an effective means to improve the crack resistance of concrete. A kind of high strength concrete internal curing agent TD-1 is prepared by monomer polymerization with porous powder quartz as carrier. By comparison with reference concrete samples, adding 0.2% internal curing agent to ordinary concrete can slow down the evaporation rate of concrete surface, and reduction of heat release rate during hydration of concrete, and the cumulative heat release of concrete decreased by 11.1%, and Improvement of crack resistance of concrete. Although the porosity increased by 18.8% and the early strength decreased slightly, the pore size distribution of concrete is more uniform, and 56 d compressive strength of concrete increased by 6.7%, and the durability of concrete is also improved. The practical application shows that the self-made TD-1 internal curing agent has good ability to restrain concrete cracking. It has a good prospect of popularization and application.
