Because of the molecular gravity of cement particles, cement slurry can form flocculation structure after mixing with water, which can not participate in free flow and lubrication, thus affecting the fluidity of concrete mixtures. After adding naphthalene sulfonate, cement particles can disperse and destroy the flocculation structure, releasing part of water wrapped to participate in the flow. Thus effectively increasing the fluidity of concrete mixture.
The hydrophilic polarity of naphthalene sulfonate water reducer is very strong, which can effectively reduce the sliding resistance between cement particles and further improve the fluidity of concrete. Naphthalene sulfonate superplasticizer can improve the dispersion effect of cement particles and control slump loss.
