About polycarboxylic acid superplasticizer polycarboxylic acid superplasticizer is a concrete admixture that can reduce the consumption of water for mixing without essentially changing the concrete slump. Most of them are anionic surfactants such as lignosulfonate, naphthalenesulfonate formaldehyde polymer. After adding the concrete mixture, it can disperse cement particles, which can improve its workability, reduce unit water consumption, and improve the fluidity of the concrete mixture. Or reduce unit cement consumption and save cement. Appearance morphology is divided into liquid and powder. The solid content of water is generally 20%, 40% (also known as mother liquor), 60%, and the solid content of powder is generally 98%. Depending on the polycarboxylic acid superplasticizer / enhancing capacity of the water-reducing agent. It is divided into a normal polycarboxylic acid superplasticizer (also called a plasticizer and a water-reducing rate typified by lignosulfonate of 8% or more) and a high-performance water-reducing agent (also called a high-performance water-reducing agent). Will be. , Naphthalene, melamine, sulfamate, aliphatic, etc. are represented by a water reduction rate of 14% or more, and a high-performance water reduction agent (water reduction rate of 25% or more, including polycarboxylic acid). It can be divided into water reducing agent), early strength type, standard type, […]
