The invention belongs to the technical field of concrete additives, and provides a concrete additive and a preparation method thereof. The concrete additive is prepared from the following components in parts by weight: 10-15 parts of a water reducer, 0.05-0.1 part of a modified defoamer, and 0.02-0.06 part of a short fiber dispersant. When the concrete additive is prepared, the modified silicone oil is emulsified at first; the emulsified modified silicone oil has excellent chemical stability, heat resistance, cold resistance, weather resistance, lubricity, hydrophobicity and low surface tension; and when the concrete additive is applied to concrete preparation, the strength and impermeability of concrete are effectively improved.
本发明公开了混凝土外加剂技术领域，提供了一种混凝土添加剂及其制备方法，所述一种混凝土添加剂，由以下重量份的组分制成：减水剂10‑15份、改性消泡剂0.05‑0.1份、短纤维分散剂0.02‑0.06份。本发明在制备混凝土添加剂时，先对改性硅油进行乳化，乳化后的改性硅油具有优异的化学稳定性、耐热耐寒性、耐侯性、润滑性、憎水性和低表面张力，应用于混凝土配制中有效提高混凝土的强度和防渗性能。
