Synthesis and Properties of a Polycarboxylate Superplasticizer with a

Polycarboxylate superplasticizers (PCEs) emerged as one of the most important superplasticizers for concrete due to their superior performance. (1,2) Compared to other products like polycondensates, they fluidize cement even at low water to cement ratios, require relatively low dosages, and exhibit a long slump retention capability. (3?5) The hi...

Progresses in Synthesis of Polycarboxylate Superplasticizer - Hindawi

Introduction Polycarboxylate superplasticizer (PCE) was synthesized by unsaturated monomers of carboxylic acid, alkane macromonomers of long chains, and others. It was an excellent cement dispersant which would make great performance in concrete [ 1 ].

Polycarboxylate ether/ester (PCE) superplasticizers are widely used due to their molecular structural designability, low dosage and high efficiency. However, their high sensitivity and strong interactions with clays in concrete reduce their dispersion and water-reduction capability, which can affect the performance of concrete seriously.

Adsorption properties of polycarboxylate ether-based superplasticizer

Abstract The cement dispersion performance of a polycarboxylate (PCE)-based superplasticizer is highly related to their adsorption behaviors as a function of time. This study evaluated effects of PCEs on rheological properties of cementitious materials.

Effect of molecular architecture of polycarboxylate ethers on

A range of anionic and cationic polycarboxylate ether (PCE) plasticizers with different molecular architectures (molecular weights, side chain lengths, and ratios of side chain density to backbone charge) are synthesized and tested to determine their effects on the rheological properties of fresh alkali-activated slag (AAS) pastes. A higher density of long side chains in the lower molecular
