Preparation of sustained-release type and superplasticizer for precast superplasticizer. Powder preparation technology superplasticizer Haimen polycarboxylate water reducer, superplasticizer compatibility with other additives Haimen Polycarboxylate polycarboxylic acid water reducing engineering agents, structural characteristics and properties of the ceramic industry with superplasticizer and its preparation method, CWS industries with Polycarboxylate dispersants. Appendix also lists the relevant standards and determination of superplasticizer. The book is rich in content, advanced technology, practical, superplasticizer for production, sales, applications, and research provide a useful reference, and for college related professional undergraduate and graduate teaching reference books. Recognized as the world's excellent performance superplasticizer, polycarboxylate superplasticizer exhibited a series of very good performance. Usually mainly in the following aspects: (1) content of low Haimen polycarboxylate water reducer, high dispersion. Water reduction up to 30%, at 0.2% -0.5% of the content can be given to concrete and mortar of high liquidity; (2) the slump is good, within 90min slump substantially without loss; (3) In the same liquidity situation, little effect on the cement setting time, can be a good solution to reduce water, air entraining, retarding, bleeding and other problems; (4) and cement, blending materials and other types of concrete admixtures phase compatibility is very good, with traditional superplasticizer such as aliphatic superplasticizer compound can produce a good additive effect; efficient Polycarboxylate _ high-strength building materials (online consultation) _ Haimen Polycarboxylate by the Linyi City high-strength building materials Limited.
