Concrete synergist and preparation method thereof
The invention discloses a concrete synergist which specifically comprises the following raw materials in parts by weight: 2-4 parts of modified polymeric alcohol amine, 0.1-0.5 part of diethanolisopropanolamine, 0.1-0.5 part of ethylene glycol, 0.1-0.5 part of a defoaming agent, 0.5-1.5 parts of sodium nitrate and 45-93.5 parts of water. According to the invention, a synthesis technology of macromolecular chain grafted functional groups is adopted, a more stable novel macromolecular polymeric alcohol amine structure is obtained, innovation in principle is achieved, and the concrete synergist is a product prepared by mixing a polymeric alcohol amine material with other functional materials. Aiming at the characteristics of various materials of concrete and water reducing agents, the invention particularly develops a novel concrete admixture which is mainly used for enhancing the strength of concrete, enhancing the durability of the concrete and improving the workability of the concrete.The concrete synergist can stimulate the activity of cement in the concrete, so that cement particles in the concrete are more dispersed, agglomeration of the cement particles is prevented, the hydration process of the cement is further accelerated, the early strength and the later strength of the concrete are obviously improved, and the later strength of the concrete is not shrunk.
本发明公开了一种混凝土增效剂，具体包括以下原料份数，其中改性聚合醇胺2‑4份，二乙醇单异丙醇胺0.1‑0.5份，乙二醇0.1‑0.5份，消泡剂0.1‑0.5份，硝酸钠0.5‑1.5份，水45‑93.5份。本发明采用大分子链嫁接官能团的合成技术，获得更加稳定的新型高分子聚合醇胺结构来实现的，做到了从原理上的创新，是聚合醇胺材料与其他功能材料混合后制备的产品，针对混凝土各类材料和减水剂的特性，特别开发出的增加混凝土强度、提高混凝土耐久性和改善混凝土和易性为主导目的的新型混凝土外加剂，该混凝土增效剂可激发混凝土中水泥的活性，使混凝土中水泥颗粒更加分散，防止水泥颗粒团聚，进而加速水泥水化过程，对增加混凝土早后期强度有明现的提升效果，混凝土后期强度无倒缩现象。
