Anti-cracking and anti-seepage concrete and preparation process thereof
The invention relates to the technical field of concrete, and discloses anti-cracking and anti-seepage concrete and a preparation process thereof, and the anti-cracking and anti-seepage concrete comprises the following substances by weight: 300-360 parts of cement; 1050 to 1100 parts of stone; 10-15 parts of waste gypsum ceramic mold powder; 0.5-1 part of a reinforcing agent; 0.010 to 0.05 part of a defoaming agent; 0.010 to 0.05 part of a hydrophobic surface active agent; 15 to 20 parts of quartz fiber; 160 to 190 parts of water; and 1-2 parts of a polycarboxylate superplasticizer. According to the invention, an effective isolation layer is formed on the concrete surface, so that water evaporation can be reduced, good plastic shrinkage surface crack resistance is achieved, crack control is carried out in the concrete setting and hardening process, the concrete hydration heat release rate and pore solution surface energy can be effectively improved, and the effect of eliminating concrete temperature stress and shrinkage cracks is achieved.
本发明涉及混凝土技术领域，公开了一种防裂抗渗混凝土及其制备工艺，本发明包括由以下重量份数的物质组成：水泥300‑360份；石子1050‑1100份；废旧石膏陶瓷模具粉10‑15份；增强剂0.5‑1份；消泡剂0.010‑0.05份；憎水性表面活性剂0.010‑0.05份；石英纤维15‑20份；水160‑190份；聚羧酸减水剂1‑2份。本发明通过凝土表面形成有效的隔离层，能降低水分蒸发，具有良好的防塑性收缩表面裂缝性能，从混凝土凝结硬化过程中进行裂缝控制，能有效改善混凝土水化放热速率和孔溶液表面能，实现消除混凝土温度应力及干缩裂缝的作用。
