As a new generation of water reducing agent, polycarboxylic acid water reducing agent is widely used in concrete engineering, but there are still some problems in the process of use that are difficult and difficult to solve. Therefore, some matters should be brought to our attention during use.

In the early 19th century, dispersive admixtures were used. However, in the 1960s, sulphonated melamine formaldehydes and analogous naphthalene derivatives were introduced. Nowadays, new admixtures based on polycarboxylate ethers are being developed. Polycarboxylate ethers possess structural characteristics that provide more fluid concrete, which is more resistant to segregation and exudation as compared to that prepared with the previously known superplasticizers. Polycarboxylate ethers have been commonly utilized to enhance the flow ability of cementitious materials. Moreover, polycarboxylate ether is one of the most effective types of plasticizers, water reducer, and disperser which promotes excellent flow ability, high strength, workability, and pump ability, and efficient dispersion for gypsum, cement, and ceramic materials.

TPEG polyether water reducer has better performance than APEG in terms of the effect on polycarboxylate superplasticizer Under the same synthetic process conditions, the performance of polycarboxylate superplasticizers prepared by TPEG polyethers of different manufacturers in accordance with national standards is significantly different. TPEG polyether has a great influence on the cement adaptability of polycarboxylate superplasticizer and concrete performance.

TEA) polymerization to obtain intermediate M, and then with isoprenol polyoxyethylene ether (TPEG), acrylic acid (AA) polymerized under aqueous conditions to obtain polycarboxylic acid - Alkanolamine cement grinding aids,

Polyether monomer in the Chinese market mainly refers to methoxy polyethylene glycol (MPEG), allyloxy polyethylene glycol (APEG), tresylated polyethylene glycol (TPEG) and isobutylene alcohol polyoxyethylene ether (HPEG). The field in which polyether monomer finds most application comes to polycarbo
