Slump Retention Masterbatch‌ is a polycarboxylate-based high-performance concrete admixture designed to maintain workability over extended periods. It ensures stable slump and flow retention during transportation and pumping, especially under high-temperature conditions or long-distance delivery.

Key Advantages

‌1、Exceptional Slump Retention‌:Effectively prevents slump and flow loss for ‌2–6 hours‌, ensuring consistent workability from batching plant to placement site, minimizing risks of blockage or construction delays.

2、‌High Compatibility and Stability: Works well with various cement types (e.g., P·O 42.5) and supplementary materials (e.g., fly ash, slag), and shows strong tolerance to aggregate variations (such as fluctuating clay content), enhancing overall admixture system stability.

3、‌Superior Construction Performance: Ideal for ‌mass concrete, self-compacting concrete, and high-rise pumping applications‌ where high flowability is critical, significantly improving construction efficiency and structural uniformity.

4、Tunable Molecular Structure:Incorporates ester-based slow-release monomers (e.g., hydroxyethyl acrylate) to achieve gradual dispersion, avoiding excessive initial fluidity that may lead to segregation or bleeding—enabling "‌smooth release, sustained slump retention‌". ~229%;7d 达160%~200%;28d达147%~187%。

5、Environmentally Friendly:Non-toxic and pollution-free during production and use, compliant with international environmental standards such as ‌ISO 14000‌.

Versatile Applications

Compatible with various types of cement and aggregates, it is widely used in mass concrete, self-compacting concrete, and long-distance pumping construction scenarios, featuring high water reduction rate, strong stability, and green environmental protection properties.
