摘要
聚羧酸高效减水剂的掺量低,减水率高,可降低混凝土的用水量,节约胶凝材料。保持水胶比不变,还可提高强度,可抑制混凝土的坍落度经时损失,保持混凝土有一个良好的工作性,并且适合配置高性能、耐久性混凝土。随着聚羧酸高效减水剂的不断完善,它必定在高性能、耐久性混凝土方面有越来越广泛的应用。
Polycarboxylate superplasticizer dosage is low, water - reducing rate, can reduce the water consumption of concrete, eementitious material savings. To maintain constant water cement ratio, but also to improve strength, inhibit the slump of concrete by the time the loss, keep the concrete has a good workability, and is suitable for configuring high - performance, durability of concrete. With the polyearboxylate superplastieizer continuous improvement, it must be in high - performance, durability of concrete has become increasingly widely used.
