The Preparation Research of Powder Polycarboxylate Superplasticizer

Applied Mechanics and Materials, 2011
This paper uses centrifugal spray drying process to prepare powder polycarboxylate superplasticizer. The best spray drying process: speed of centrifugal atomizer is 16000r/min, feed liquid temperature is 30°C, import / export air temperature of drying chamber is 200°C/80°C. It achieves a high concentration of polycarboxylate superplasticizer to prepare

Preparation and Properties of New Polycarboxylate-Type Superplasticizer

Advanced Materials Research, 2011
A modified polycarboxylate superplasticizer was synthesized by copolymerization of polyethylene glycol monomethyl ether methacrylate (MPEG-MA), β–Cyclodextrins grafted maleic anhydride (MAH-β-CD), methacrylic acid (MAA) and methallyl sulfonic acid (MAS). The excellent superplasticizer was obtained at the molar ratio of n(MAH-β-CD) : n(MAS) : n(MAA) : n(

Comparison of ester-based slow-release polycarboxylate superplasticizers with their polycarboxylate counterparts

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2022
Abstract Ester-based slow-release polycarboxylate superplasticizers (PCT) exhibit high fluidity and a good slump retention effect on concrete slurries. Hence, in this study, a previously prepared unsaturated triethyl citrate (as the functional monomer) and acrylic acid and isoprenyloxy polyethylene glycol (as the primary raw materials) were employed ...
