Concrete water reducer
The invention belongs to the technical field of constructional engineering, and particularly relates to a concrete water reducer, which is prepared by compounding the following raw materials and water: 160 kg of a water reducing master batch, 40 kg of a slump retaining master batch, 30 kg of sodium gluconate, 5 kg of cellulose, 5 kg of a defoaming agent and 5 kg of an air entraining agent, wherein the total of the raw materials and water is 1000 kg, and the water reducing master batch is a polycarboxylic acid water reducer mother liquor containing HPEG, TPEG and S-PEGs. In the water reducing master batch, the slump retaining property and adaptability of the water reducing agent are ensured by using the TPEG, and part of the HPEG and the S-PEGs are adopted, so that the production cost is further reduced.
本发明属于建筑工程技术领域，具体涉及一种混凝土减水剂，由以下原料和水复配而成：减水母料160kg、保坍母料40kg、葡萄糖酸钠30kg、纤维素5kg、消泡剂5kg份、引气剂5kg份，其中原料和水总计1000kg，所述的减水母料为包含HPEG、TPEG和S‑PEGs的聚羧酸减水剂母液。本申请的减水母料中，在使用TPEG的保证减水剂的保坍性和适应性同时，采用了部分HPEG和S‑PEGs，从而使得生产成本进一步降低。
