The invention relates to the technical field of concrete admixtures, and relates to an early strength water reducing agent and a preparation method thereof. The early strength water reducing agent comprises the following components by mass: 65-85 parts of deionized water, 50-55 parts of a polycarboxylic acid water reducing agent, 15-20 parts of tree ash powder, 10-16 parts of sepiolite powder, 3-7parts of triethanolamine and 1-3 parts of an antifoaming agent; the preparation method comprises the following steps: S1, mixing corresponding parts by mass of deionized water, the polycarboxylic acid water reducing agent and triethanolamine, and uniformly stirring at 30-35 DEG C for 5-10 minutes to obtain a mixture A; S2, adding corresponding parts by mass of tree ash, sepiolite powder and hollow glass beads into the mixture A while stirring to obtain a mixture B; S3, adding corresponding parts by mass of the antifoaming agent into the mixture B, and stirring to obtain the early-strength water reducing agent; the early strength water reducing agent provided by the invention has the advantage of good dispersibility, and can improve the effect of improving the early strength of concrete.
本发明涉及混凝土外加剂技术领域，它涉及一种早强减水剂及其制备方法，包括以下组分及质量份：去离子水65‑85份、聚羧酸系减水剂50‑55份、树木灰烬粉末15‑20份、海泡石粉10‑16份、三乙醇胺3‑7份和消泡剂1‑3份；制备步骤：S1、将相应质量份的去离子水、聚羧酸系减水剂以及三乙醇胺混合，在30‑35℃的条件下均匀搅拌5‑10min，得到混合物A；S2、边搅拌边往混合物A添加相应质量份的树木灰烬、海泡石粉以及空心玻璃微珠，制得混合物B；S3、往混合物B添加相应质量份的消泡剂，搅拌制得早强减水剂；本发明提供的早强减水剂具有分散性好的优点，能提高对混凝土早期强度的提升作用。
