The invention relates to the field of concrete, in particular to C40 medium-strength resin concrete and a preparation method thereof. The concrete is prepared from the following raw materials in parts by weight: 230-250 parts of Portland cement, 90-110 parts of mineral powder, 60-100 parts of fly ash, 950-1000 parts of coarse aggregate, 700-800 parts of fine aggregate, 8-10 parts of an additional water reducing agent, 170-180 parts of water, 80-1000 parts of a resin additive and 2-3 parts of a curing agent, the resin additive is composed of epoxy resin and a reinforcing agent according to a mass ratio of (15-18): (1-2); the reinforcing agent is at least one of dibutyl phthalate and liquid nitrile rubber. The preparation method has the advantage of improving the strength of the prepared concrete.
本申请涉及混凝土领域，更具体地说，它涉及一种C40中强度树脂混凝土及其制备方法；由如下重量份数的原料制成：硅酸盐水泥230‑250份、矿粉90‑110份、粉煤灰60‑100份、粗骨料950‑1000份、细骨料700‑800份、外加减水剂8‑10份、水170‑180份、树脂添加剂80‑1000份、固化剂2‑3份；所用树脂添加剂由环氧树脂和增强剂按照质量比（15‑18）：（1‑2）组成；所用增强剂为邻苯二甲酸二丁酯、液体丁腈橡胶中的至少一种。本申请具有提高制备的混凝土的强度的优点。
