Spatial Steric Resistance Of Water-reducing Agent
Aug 21, 2018

In the structure of water-reducing agent, the hydrophilic branched chain is extended in aqueous solution to form a hydrophilic solid adsorption layer with a certain thickness on the surface of the adsorbed cement particles. When the cement particles close, the adsorption layer began to overlap, that is, in the cement particles in the space between the role of resistance, overlap, the greater the space resistance repulsion, the cement particles in the cohesion of the greater obstacles, so that the concrete slump to maintain good.
