The invention discloses a concrete water reducing agent for reducing slump. The concrete water reducing agent is prepared from the following raw materials in parts by weight: 40-60 parts of polycarboxylate superplasticizer mother liquor, 2-3 parts of polyoxyethylene polyoxypropanolamine ether, 2-3 parts of a catalyst, 6-12 parts of lignosulfonate, 1-3 parts of nitrate, 2-3 parts of sodium gluconate, 10-16 parts of an organic acid retarder, 10-25 parts of microcrystalline white mica powder, 3-5 parts of a dispersing agent, 5-10 parts of a concrete defoaming agent and 30-45 parts of water. According to the invention, polycarboxylate superplasticizer mother liquor, polyoxyethylene polyoxypropanolamine ether, catalyst, lignosulfonate, nitrate, sodium gluconate, organic acid retarder, microcrystalline white mica powder, dispersing agent, concrete defoamer and other materials do not contain harmful elements, have the effect of enhancing the strength of concrete, have obvious effect on reducing the slump of concrete, and further have the effects of absorbing ultraviolet rays and being high in durability and strength are achieved.
本发明公开了一种降低坍落度的混凝土减水剂，包括以下重量份的原料：聚羧酸减水剂母液40‑60份、聚氧乙烯聚氧丙醇胺醚2‑3份、催化剂2‑3份、木质素磺酸盐6‑12份、硝酸盐1‑3份、葡萄糖酸钠2‑3份、有机酸类缓凝剂10‑16、微晶白云母粉10‑25份、分散剂3‑5份、混凝土消泡剂5‑10份、水30‑45份。本发明通过聚羧酸减水剂母液、聚氧乙烯聚氧丙醇胺醚、催化剂、木质素磺酸盐、硝酸盐、葡萄糖酸钠、有机酸类缓凝剂、微晶白云母粉、分散剂、混凝土消泡剂等材料不含有有害元素，具有加强混凝土强度的作用，对降低混凝土坍落度效果显著，同时还具有吸收紫外线、耐用强度高的功效。
