The research and application of NF acyclic superplasticizer;

Study on synthetic technology of aliphatic hydroxy sulphonate condensate superplasticizer;

It was forecast that study and application of aliphatic water reducers had abright prospect for deployment.

Effects of content of reactants and species of sulfonating agents on dispersion of aliphatic water reducer were systematically studied and structure of self-made aliphatic water reducer was characterized by IR.

Study on hydrolysis process of synthesizing technology of naphthalene-based superplasticizer;

Study of thermal compounding of naphthalene-based superplasticizer and aminosulfonate-based superplasticizer was carried out Testing results showed that compared with compounding at normal temperature, thermal compounding at 55 ℃ could enhance water reduction of the compounded superplasticizer and its compatibility with cement, lower elapsed slump loss of concrete.

Owing to the situations of research and application of naphthalene-based, aminosulfonic - based superplasticizers and their compounding performance, firstly, the hydrolysis process of synthesizing technology of naphthalene-based superplasticizer was systematically investigated, which has hardly been studid from now on.

Research and application of polycarboxylate type superplasticizers;

Study of adsorbability of cement for superplasticizer with different clinker modulus and mineral composition;

Overview of research on modification of superplasticizer;

Study on a new polycarboxylate-tape of super plasticizer;

The development of super plasticizer with copolymerized carboxylic acid;

This paper presents a study on the preparation of the high volume fly ash (HVFA) concrete, which super plasticizer with carboxylic acid was used m the HVFA and dosage of fly ash is respectively 40%, 60%, and 70%.
