Concrete containing polycarboxylic acid super-retarding water reducing agent and preparation method thereof
The invention relates to the field of concrete, and particularly discloses concrete containing a polycarboxylic acid super-retarding water reducing agent and a preparation method of the concrete. The concrete containing the polycarboxylic acid super-retarding water reducing agent is prepared from a concrete mixing material. The concrete mixing material comprises the following components in parts by mass: water, cement, fly ash, sand, stone and the polycarboxylic acid super-retarding water reducing agent, wherein the polycarboxylic acid super-retarding water reducing agent is a compound of triethanolamine oleate, tetrapolyethylene glycol monooctyl ether, polyethylene glycol monooleate and polyoxyethyl glyceryl ether. The preparation method comprises the following steps: 1) uniformly mixing the cement, the fly ash and the polycarboxylic acid super-retarding water reducing agent to obtain a premix; 2) uniformly mixing the premix, sand and stone to obtain a mixture; 3) uniformly mixing the mixture and water to obtain a concrete mixture; and (4) pouring the concrete mixture into a template, and successively carrying out curing and demolding. The concrete provided by the invention has the advantage that the plasticity of the concrete mixing material can be kept for a longer time.
本发明涉及混凝土领域，具体公开了一种含聚羧酸超缓凝减水剂的混凝土及其制备方法，含聚羧酸超缓凝减水剂的混凝土，由混凝土拌和料制成；所述混凝土拌和料包括以下质量份数的组分：水、水泥、粉煤灰、砂、石、聚羧酸超缓凝减水剂，聚羧酸超缓凝减水剂为油酸三乙醇胺、四聚乙二醇单辛醚、聚乙二醇单油酸酯、聚氧乙基甘油醚的复配。制备方法包括以下步骤：1）水泥、粉煤灰、聚羧酸超缓凝减水剂混合均匀，得预混物；2）预混物、砂、石混合均匀，得混合物；3）混合物、水混合均匀，得混凝土拌和料；4）混凝土拌和料浇筑至模板中，养护，脱模。本发明具有使混凝土拌和料在更长时间内保持可塑性的优点。
