RC-JM Polycarboxylate Ether Superplasticizer Base Liquids

Our company's Polycarboxylate Ether (PCE) Superplasticizer Base Liquids are produced using polyether macromonomers as the primary raw material, employing advanced free radical catalytic polymerization technology at ambient or low temperatures. Designed with specific ionic functional groups and a rigid molecular conformation, they provide steric hindrance and strong electrostatic repulsion. This effectively enhances the adsorption-dispersion capability and compatibility with various concrete raw materials. The products are characterized by high water reduction, excellent slump retention, and broad adaptability. The series includes Water-Reducing, Slump-Retaining, and Viscosity-Reducing/Comprehensive types.

RC-SW Type Solid-Waste Low-Carbon Cementitious Admixture

This product is a high-performance grinding aid and super-dispersant specifically designed for micro-nano grade ultrafine supplementary cementitious materials and solid waste-based low-carbon cementitious materials. Through multiple action mechanisms, it effectively addresses core challenges in ultrafine grinding processes such as low efficiency, high energy consumption, easy agglomeration, and insufficient activation. It is a key chemical additive for achieving high-value and resourceful utilization of solid waste.

RC-LC LC-P Type Low-Carbon Cement Activator

The LC Type Powder Activator is a dry powder composite material made from modified sulfates, alkaline components, and functional additives through scientific proportioning and fine grinding. It is strictly designed according to the requirements of the Chinese Building Materials Industry Standard JC/T 2475-2023 "Gypsum-Slag Cement". Specifically intended for gypsum-slag-clinker composite systems, it is added at a recommended dosage of 2% of the total cementitious material mass and co-ground with clinker, gypsum, and slag powder. It efficiently activates slag activity and significantly optimizes cement performance, serving as the core material for producing green, low-carbon cement that fully complies with national standards.
