Preparation process of high-performance anti-crack concrete
The invention relates to the technical field of concrete, in particular to a preparation process of high-performance anti-crack concrete, which comprises the following steps: preparing the preparation raw materials of a high-performance anti-crack concrete primary mixture: 160-220 parts of Portland cement, 80-120 parts of fly ash, 50-70 parts of slag, 30-50 parts of silica fume and 28-35 parts of fine aggregate; the concrete is prepared from the following raw materials in parts by weight: 28-35 parts of coarse aggregate, 18-26 parts of a composite expanding agent, 16-22 parts of a fiber anti-cracking agent and 250-400 parts of water. Preparing a high-performance anti-crack concrete primary mixture; the high-performance anti-crack concrete primary mixture is taken out and poured, and a wear-resistant material is spread on the surface of the poured high-performance anti-crack concrete primary mixture layer for wear-resistant treatment; and curing the concrete layer subjected to wear-resistant treatment. According to the preparation process of the high-performance anti-crack concrete, the preparation process is simple, the raw materials are easy to obtain, the cost is low, the prepared concrete has the advantages of being high in wear resistance, high in strength, easy to clean and the like while having excellent anti-crack and anti-seepage performance and high hardening strength, and the application range of the concrete is widened.
本发明涉及混凝土技术领域，尤其为一种高性能抗裂混凝土的制备工艺，包括以下步骤：准备高性能抗裂混凝土初混物的制备原料：硅酸盐水泥160‑220份、粉煤灰80‑120份、矿渣50‑70份、硅灰30‑50份、细骨料28‑35份，粗骨料28‑35份、复合型膨胀剂18‑26份、纤维抗裂剂16‑22份、水250‑400份；制备高性能抗裂混凝土初混物；将高性能抗裂混凝土初混物取出并进行浇筑，往浇筑后的高性能抗裂混凝土初混物层表面撒布耐磨材料进行耐磨处理；对耐磨处理后的混凝土层进行养护。本发明所述的一种高性能抗裂混凝土的制备工艺，制备工艺简单，原料易得、成本低廉，制备得到的混凝土在具有优良的抗裂防渗性能，硬化强度高的同时，具有耐磨性强、强度高、易清洁等优点，扩大了混凝土的使用范围。
