Polycarboxylate superplasticizer for recycled aggregate concrete
The invention provides a polycarboxylate superplasticizer for recycled aggregate concrete. The polycarboxylate superplasticizer comprises water, a polycarboxylic acid water reducing mother solution, a polycarboxylic acid slump retaining mother solution, sodium gluconate and an air entraining agent. The polycarboxylate superplasticizer for the recycled aggregate concrete is prepared from three basic raw materials including the water reducing mother solution, the slump retaining mother solution and the sodium gluconate, the optimal titration sequence and the optimal component proportion are determined, and on the basis that the performance of the recycled aggregate concrete is guaranteed, the cost is lowest, and the profit rate is maximum.
本发明提供了一种用于再生骨料混凝土的聚羧酸减水剂，所述减水剂包括水、聚羧酸减水母液、聚羧酸保坍母液、葡萄糖酸钠和引气剂；该用于再生骨料混凝土的聚羧酸减水剂，由减水母液、保坍母液、葡萄糖酸钠三种基本原料为组分，确定最佳滴定顺序及最优成分配比，在保证再生骨料混凝土性能的基础上，成本最低，利润率最大。
