Polycarboxylate Superplasticizer(PCE), also called water reducer, is an innovative and advanced chemical additive used in concrete and mortars. It significantly improves the flowability<\/strong> <\/em>without increasing the water content. This allows for high-strength<\/strong><\/em>, high-performance concrete and mortar with lower water-to-cement ratios. Also, it can accelerate the early strength development<\/strong><\/em> of concrete or mortar.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

  • Reduce Water Content: PCE-based superplasticizers can significantly reduce water content by up to 40% at low dosages of around 0.12% to 0.22% without compromising fluidity.<\/span><\/li>
  • Improve Strength: Polycarboxylate Superplasticizer could accelerate the early strength development of concrete and mortar. <\/span><\/li>
  • Slump Retention: Polycarboxylate Superplasticizer ensures concrete consistency and workability. With a higher slump rating, concrete can be more fluid and pumpable, especially for projects involving long-distance pumping and bulk construction.<\/span><\/li><\/ul><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

    The PCE molecules absorbed onto cement particles have an electrostatic repulsion and steric effects. This can prevent cement particles from holding together due to electrostatic force. As a result, cement can be evenly dispersed in water. Such a dispersion allows the concrete to flow more easily with less water.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

    • Compatibility: Polycarboxylate Superplasticizer is well compatible with various gypsum and cement including quick-setting and low-heat cement. It can be used with other chemical additives, such as anti-foaming agents and gypsum retarders.<\/span><\/li>
    • Environmentally Friendly: The production of PCE uses no formaldehyde, free of toxic, public nuisance, or any pungent odor.<\/span><\/li>
    • Save Costs: Thanks to Polycarboxylate Superplasticizer, it is viable to replace cement with slag or fly ash which are much cheaper.<\/span><\/li>
    • Low Content of Chloride and Alkali: PCE could reduce steel corrosion to improve the durability of concrete and mortar.<\/span><\/li>
    • Flexible Molecular Structure: The comb-like structure of the Polycarboxylate Superplasticizer is designed to achieve tailored performance for various concrete and mortar. By adjusting the chemistry and length of the main chain and, the length and density of the side chain, PCE could have a specific water reduction rate, workability, rheological behavior, strength, air content, and working time.<\/span><\/li><\/ul><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t
