Preparation method of workability regulator for machine-made sand concrete
The invention discloses a preparation method of a workability regulator for machine-made sand concrete, and belongs to the field of processing of building material admixtures. Comprising the following steps: acidizing, hydrolyzing and chemically modifying the waste cotton fabric, and performing ultrasonic treatment to obtain regenerated hydrolyzed cellulose; the preparation method comprises the following steps: dissolving unsaturated polyoxyethylene ether, adding regenerated hydrolyzed cellulose, gamma-methacryloxypropyltrimethoxysilane and unsaturated carboxylic acid, heating to 75-85 DEG C, stirring for 30-60 minutes, heating to 80-100 DEG C, dropwise adding the material A, the material B and the material C at a constant speed, and stirring for 60 minutes after dropwise adding is finished, so as to obtain the machine-made sand concrete workability regulator. The workability regulator prepared by the method can significantly improve workability of machine-made sand concrete, improve homogeneity and stability of the concrete, and ensure construction performance, strength performance and durability of the concrete.
本发明公开了一种机制砂混凝土和易性调节剂的制备方法，属于建筑材料外加剂加工领域。包括以下步骤：将废旧棉织物酸化水解、化学改性后进行超声处理，得再生水解纤维素；将不饱和聚氧乙烯醚溶解，加入再生水解纤维素、γ‑甲基丙烯酰氧基丙基三甲氧基硅烷、不饱和羧酸，升温至75‑85℃后搅拌30‑60min，再升温至80‑100℃，匀速滴加A料、B料、C料，滴加结束后搅拌60min，即得到机制砂混凝土和易性调节剂。本发明方法制备的和易性调节剂可以显著改善机制砂混凝土和易性，提高混凝土匀质性和稳定性，保证混凝土的施工性能、强度性能和耐久性能。
