Product Description
ZHUOJUN® Polycarboxylic Acid Superplasticizers (PCEs), also known as ZHUOJUN® high range water reducers (HRWR), are external additives, which can greatly reduce water demand and cement contents by both effects of electrostatic repulsion and entropic stabilization. ZHUOJUN® PCEs can also achieve higher strength of concrete and maintain the fluidity of concrete much longer than normally observed with Naphthalene based polymers and Melamine based polymers without excessive retardation.
They are widely applied in construction projects, like high-rise buildings, large dams, bridges, tunnels, and national defense projects.
Main Mechanism
As a surfactant, ZHUOJUN® PCEs belong to anionic surfactants. It adsorbs on the surface of cement particles to show the electrical properties of the particles. Particles are mutually exclusive due to the same charge in order to disperse the cement particles to release excess water between the particles to reduce in water content. On the other hand, After adding the ZHUOJUN® PCEs, the adsorption film is formed on the surface of the cement particles, which affects the hydration speed of the cement, makes the growth of the cement stone crystal more perfect, reduces the capillary gap of water evaporation, and makes the network structure more compact. Thus the hardness of the cement mortar is improved and the compactness of cement mortar structure is improved.
