从China供应商批发进口Air-Entraining And Retarder Superplasticizer — FOB条款

This liquid superplasticizer from Beijing Ruidisi Building Materials Co., Ltd combines polycarboxylate ether (PCE) chemistry with air-entraining and set-retarding agents to deliver a multi-functional admixture for concrete. It conforms to ASTM C494 and EN 934-2, suitable for ready-mix, mass concrete, and high-performance applications where extended workability and freeze-thaw resistance are critical. Supplied as a concentrate in 200L drums or IBC totes, it is designed for hot-weather pours and long-distance transport without segregation.

The formulation introduces controlled micro-air voids (typical 4-6% air content) while reducing water demand by up to 25%, improving strength and durability without compromising slump retention. The retarder component extends initial setting time by 1-3 hours, depending on dosage and ambient conditions. Standard compatibility covers Portland, slag, and fly-ash cements, with chlorine-free composition to prevent corrosion in reinforced structures.

Primary buyers include ready-mix producers, infrastructure contractors, and precast manufacturers requiring consistent performance in large-volume pours. The product is sourced from ISO-certified facilities and shipped from Beijing, with trade terms negotiable per project. Buyers should confirm dosage trials for mix-specific optimization and verify compliance with local standards for air-void stability and setting characteristics.

Beijing Ruidisi Building Materials Co., Ltd operates from No. 600, Chaichangtun Village, Yongledian Town, Tongzhou District, Beijing, with a focus on high-performance concrete admixtures. The company’s profile indicates an imported supplier tier and harbor trust tier, though response metrics are currently unrecorded. Its product line centers on specialty chemicals for construction, including superplasticizers with multi-functional properties.

The supplier positions itself as a provider of ASTM and EN-compliant admixtures, emphasizing ISO-certified sourcing for its formulations. While the profile does not detail production capacity or export history, the stated address and product range suggest a focus on serving domestic and international contractors through bulk liquid shipments. Buyers are advised to confirm certification validity and production lot consistency directly with the supplier.
