Concrete glue reducing agent and preparation method thereof
The invention discloses a concrete glue reducing agent and a preparation method thereof, relates to the technical field of concrete admixtures, and is characterized in that the concrete glue reducingagent is prepared by diluting mother liquor and water, and the 100 parts of mother liquor is prepared from the following components in parts by weight: 45-55 parts of mixed alcohol amine, 4-6 parts ofanhydrous sodium metasilicate, 5-7 parts of lithium silicate, 15-20 parts of methyl sodium silicate and the balance of water. The concrete glue reducing agent disclosed by the invention has the advantages that the cement dosage can be reduced, and the fluidity of a concrete mixture and the coating property of cement on aggregate are improved, so that the workability of concrete is improved.
本发明公开了一种混凝土减胶剂及其制备方法，涉及混凝土外加剂技术领域，其技术方案要点是一种混凝土减胶剂，由母液与水稀释后制得，以100重量份母液计，包括如下组分：混合醇胺45‑55份、无水偏硅酸钠4‑6份、硅酸锂5‑7份、甲基硅酸钠15‑20份，余量为水。本发明的混凝土减胶剂，具有可以降低水泥用量、提高混凝土拌合物的流动性以及水泥对骨料的包裹性，从而改善混凝土的和易性的优点。
