Retarding type water reducing agent for high-performance concrete and use method of retarding type water reducing agent
The invention provides a retarding type water reducing agent for high-performance concrete and a use method of the retarding type water reducing agent. The retarding type water reducing agent comprises the following components: a polycarboxylic acid water reducing agent, a straw alkali-soluble substance, sodium gluconate, sodium tripolyphosphate, lignosulfonate and an odor camphor super plasticizer. The doping amount of the polycarboxylic acid water reducing agent and the lignosulfonate accounts for 0.5-0.7% of the mass of the concrete; the doping amount of the straw alkali-soluble substance, the sodium gluconate, the sodium tripolyphosphate and the stink camphor superplasticizer accounts for 2-2.5% of the mass of the concrete; by optimizing the mass ratio of the straw alkali-soluble substance to the sodium gluconate, the sodium tripolyphosphate, the lignosulfonate and the smelly camphor superplasticizer, the synergistic effect of all the components is exerted, the water reducing and retarding effects of the water reducing agent are further enhanced, and meanwhile the flowability of concrete can be kept.
本发明提供了一种用于高性能混凝土的缓凝型减水剂及其使用方法，包括以下组分：聚羧酸类减水剂、秸秆碱溶物、葡萄糖酸钠、三聚磷酸钠、木质磺酸盐、臭樟脑超塑化剂；所述聚羧酸类减水剂与木质磺酸盐的掺杂量为占混凝土质量的0.5～0.7％；所述秸秆碱溶物与葡萄糖酸钠、三聚磷酸钠、臭樟脑超塑化剂的掺杂量为占混凝土质量的2～2.5％；通过优化秸秆碱溶物与葡萄糖酸钠、三聚磷酸钠、木质磺酸盐、臭樟脑超塑化剂的质量比，发挥各组分之间的协同作用，进一步增强减水剂的减水以及缓凝作用，同时还能保持混凝土的流动性。
