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.

RC-J Superplasticizer Series

This series of products comprises compound polycarboxylate superplasticizers. They can be tailored to meet specific project requirements, providing customers with optimized, personalized products and technical solutions. The product performance indicators fully comply with the requirements of relevant standards such as GB 8076 and TB/T 3275. The products are categorized into the following types: early-strength, standard, retarding, and clay-tolerant. They feature a high water reduction rate, excellent slump retention, and low sensitivity to variations in raw materials. These superplasticizers are suitable for high-strength and high-performance concrete, ready-mixed concrete, and are particularly recommended for producing commercial concrete and high-fluidity concrete, among other high-performance applications.

RC-A Series High-Efficiency Grinding Aids

The RC-A Series High-Efficiency Grinding Aid is a new grinding product specifically developed for cement enterprises, aiming to enhance cement quality, optimize particle size distribution, improve grinding efficiency, and achieve cost reduction and efficiency improvement.

RC-RM Series High-Efficiency Composite Raw Meal Grinding Aids

Runchang® RC-RM Series High-Efficiency Composite Raw Meal Grinding Aids are core energy-saving and consumption-reducing products developed by our company for modern new dry process cement production lines. Its mechanism is a multi-functional synergistic system spanning the entire grinding and sintering process. It adsorbs onto material particle surfaces and crack tips via polar groups, significantly reducing surface energy and micro-hardness, utilizing the Rebinder effect to enhance grinding efficiency, and inhibiting particle re-agglomeration through steric hindrance and electrostatic repulsion, optimizing particle size distribution and fluidity.
