Reducing Agent

We respectively conduct performance contrast test on cement paste, cement mortar, and high-performance concrete which have been added naphthalene water-reducing agent and polycarboxylate water-reducing agent. Studies show that naphthalene water-reducing agent can better improve the performance of concrete and increase the fluidity of concrete to ensure its keeping slump. Meanwhile, the age strength and the growth rate of strength of concrete with mixing polycarboxylate water-reducing agent has been significantly improved than those of naphthalene water-reducing agent, which can better meet the strength requirements of concrete and get a bright application prospect that naphthalene water-reducing agent can not reach.
