Novel early-strength polycarboxylate superplasticizer
The invention relates to a novel early-strength polycarboxylate superplasticizer. The novel early-strength polycarboxylate superplasticizer comprises a polycarboxylate superplasticizer, a retarder, unsaturated acid, a chain transfer agent and water. A synthesis method for the novel early-strength polycarboxylate superplasticizer is simple in process , easy to operate and high in water-reducing rate, can greatly reduce a water-cement ratio and ensures concrete strength; and the novel early-strength polycarboxylate superplasticizer is low in shrinkage rate, and can effectively improve the durability of concrete.
一种新型早强型聚羧酸减水剂,包括聚羧酸系减水剂、缓凝剂、不饱和酸、链转移剂、水。本发明工艺合成方法简单,易操作,减水率高,可大幅降低水灰比,确保混凝土强度;收缩率低,能有效提高混凝土的耐久性能。
