Preparation method of epoxy resin modified high-strength recycled concrete
The invention discloses a preparation method of epoxy resin modified high-strength recycled concrete. The method specifically comprises the following steps: (1) crushing waste concrete blocks, and screening after crushing to obtain concrete blocks with the maximum particle size of not more than 40mm; (2) classifying and screening the concrete blocks to obtain recycled concrete coarse aggregate of 5-30 mm and recycled concrete fine aggregate of 0-5 mm; and (3) blending the recycled concrete coarse aggregate, the recycled concrete fine aggregate, ordinary Portland cement, a water reducing agent, a water-borne epoxy resin emulsion, a curing agent and water, fully mixing to obtain a recycled concrete mixture, and pouring and molding the recycled concrete mixture. The recycled concrete is subjected to epoxy resin modification, so that the compressive strength and corrosion resistance of the recycled concrete can be effectively improved, and the application range of the recycled concrete is widened.
本发明公开了一种环氧树脂改性高强度再生混凝土的制备方法。该方法的具体操作为：(1)将废弃混凝土块进行破碎处理，破碎完成后通过筛分得到最大粒径不大于40mm的混凝土块；(2)通过对混凝土块分级筛选，得到5‑30mm的再生混凝土粗集料和0‑5mm的再生混凝土细集料；(3)将再生混凝土粗集料、再生混凝土细集料、普通硅酸盐水泥、减水剂、水性环氧树脂乳液、固化剂和水进行掺配，经充分拌合后可得到再生混凝土混合料，将再生混凝土混合料浇筑成型。本发明通过对再生混凝土进行环氧树脂改性，能有效提高再生混凝土的抗压强度和抗腐蚀性能，从而提高再生混凝土的使用范围。
