Super-tough concrete for prefabricated members and preparation method of super-tough concrete
The invention relates to super-tough concrete for a prefabricated member and a preparation method thereof, wherein the super-tough concrete for the prefabricated member comprises the following components in parts by weight: 120-500 parts of cement, 200-1000 parts of aggregate, 50-250 parts of a polyhydroxy compound aqueous solution and 0.1-20 part of a superplasticizer, wherein the mass concentration of the polyhydroxy compound aqueous solution is 0.01-10%. According to the invention, the polyhydroxy compound can significantly improve the flexural strength and toughness of the concrete, so that the concrete has the functional characteristics of high toughness, abrasion resistance, high damping and the like compared with a traditional concrete material, can be used as special concrete for sleepers, pavements, roadblocks, beam columns and other parts, and is used for shock absorption, energy dissipation and improvement of structural safety, durability and applicability.
本发明涉及预制构件用超韧性混凝土及其制备方法，所述的预制构件用超韧性混凝土按照重量份计，包括水泥120~500份、骨料200~1000份、多羟基化合物水溶液50~250份和高效减水剂0.1~20份；所述的多羟基化合物水溶液质量浓度为0.01%~10%。多羟基化合物可以显著提高混凝土的抗折强度和韧性，使本发明较传统混凝土材料具有高韧性、耐冲磨、高阻尼等功能特性，可作为特种混凝土用于轨枕、路面、路障、梁柱等部位，用于减震、消能，提升结构安全性、耐久性、适用性。
