White Damavand currently offers two Polycarboxylate Superplasticizers: GLSEN and RIVERTEX.
Polycarboxylate superplasticizer (PCE) is a major raw material of ‘concrete admixtures’, which becomes critical element of concrete. PCE was firstly developed over 20 years ago in Japan. PCE can greatly reduce water demand and cement contents by both effects of electrostatic and steric repulsion. PCE also maintains the fluidity of concrete much longer than normally observed with Naphthalene based polymers and Melamine based polymers without excessive retardation.
✓ Mechanical StreNgth
Higher water reduction
✓ Delivery Time
Longer slump retention
How does it work?
The main chain of PCE is polyethylene and its graft chain is composed of PEO (polyethylene Oxide) and carboxyl group. Cement particles go through physical adsorption process. At the same time, dispersion draws both electrostatic and steric repulsion and gives PCE high water reduction effect and workability.
