Property enhancement and mechanism of cement-based composites from the perspective of nano-silica dispersion improvement

Case Studies in Construction Materials
Nano-silica (NS) exhibits significant potential for enhancing the properties of cement materials. However, its effectiveness in improving the properties of cement-based materials is hindered by the poor dispersion of NS within the cement matrix.

Synthesis and performance of polycarboxylate superplasticizer with ester monomers

ce/papers
AbstractRelevant studies have shown that ester monomers improve concrete mud resistance, slump retention, fluidity and so on more obviously. In this paper, a series of polycarboxylate superplasticizer were prepared by using polyglycol maleic anhydride (PGA), phosphoric acid ester of capped amide (PCA), and methoxy polyglycol acrylate (PGMA) as the ...

Experimental evaluation of a new phosphonate-based superplasticizer for concrete

, 2012
The paper deals with the effectiveness of an innovative phosphonate-based superplasticizer (PHN) for ready mixed concrete. Concrete specimens were manufactured by considering a constant initial workability, equal to 220 mm slump at the end of the mixing ...

Effects of Lithium Carbonate and Superplasticizer on Ultra-Early Strength of Alite-Ye’elimite-Belite-Ferrite Cement

Alite-ye’elimite-belite-ferrite cement (AYBFC) integrates the advantages of calcium sulfoaluminate cement and Portland cement, but its ultra-early strength needs to be further improved when applied to rush repair and construction works.
