XRD Chemical is a professional Polycarboxylate Ether (PCE) manufacturer and supplier in China, offering high-quality PCE high slump-retention mother liquor with 40-50% solids content for formulating extended-workability concrete admixtures.
This high slump-retention type mother liquor features a specially designed comb-like molecular structure with controlled-release side chains that provide sustained cement dispersion over extended periods. Unlike standard mother liquor that prioritizes initial water reduction, this grade is engineered to maintain concrete workability for 2-4 hours after mixing. The polymer architecture gradually exposes additional carboxylate anchoring groups in the alkaline cement environment, continuously dispersing cement particles and compensating for hydration-related slump loss.
As a base polymer, it provides exceptional flexibility for formulators developing finished admixtures for ready-mix concrete with long haul times, large continuous pours, high-temperature concreting, and self-compacting concrete. It is supplied as a clear to pale yellow viscous liquid at 40-50% solids with a pH of 4-7. It can be blended with defoamers, retarders, and other modifiers to create finished products optimized for specific local conditions and application requirements.
