High-toughness concrete material for quickly repairing sewage pool building and preparation method
The invention discloses a high-toughness concrete material for quickly repairing sewage pool buildings, and the material comprises the following raw materials in parts by mass: 20-25 parts of ordinaryPortland cement, 80-100 parts of sulphoaluminate cement, 20-180 parts of water, 50-250 parts of ceramsite powder, 25-400 parts of microspheres, 2-5 parts of nano SiO2, 0.05-0.1 part of a shrinkage reducing agent, 0.1-10 part of a water reducing agent, 0.5-30 part of synthetic fibers, 1-10 parts of rubber powder and 0.1-1 part of a water repellent. The anti-cracking concrete has excellent anti-cracking performance, high bonding strength with a matrix, high toughness and high chloride ion and sulfate corrosion resistance, and through detection, the thermal expansion coefficient of the anti-cracking concrete is close to that of concrete and harmonious and consistent with the deformation of the matrix concrete, the 28d anti-abrasion strength is greater than or equal to 30h/(kg/m<2>), the anti-cracking index is 100%, and the chloride ion penetration grade is IV; the quality assurance rate after sulfate corrosion resistance is 98%, and the ultimate tensile value is 1%-3%. The invention alsohas the advantages of simple and convenient construction process, wide sources of raw materials, convenient purchase and the like.
本发明公开了一种污水池建筑快速修补的高韧性混凝土材料，其原料按照质量份计算，包括：普通硅酸盐水泥20~25份，硫铝酸盐水泥80~100份，水20~180份，陶粒粉50~250份，微珠25~400份，纳米SiO₂8~25份，减缩剂0.05~0.1份，减水剂0.1~10份，合成纤维0.5~30份，胶粉1~10份，憎水剂0.1~1份。本发明具有优异的抗裂性能，与基体粘结强度高，韧性性高，抗氯离子和硫酸盐侵蚀性能高，经检测，本发明的热膨胀系数与混凝土的接近，与基体混凝土的变形协调一致，28d抗冲磨强度≥30h/（kg/m2），抗开裂指数100%，抗氯离子渗透等级为IV级，抗硫酸盐侵蚀后质量保证率为98%，极限拉伸值1%~3%。本发明还具有施工工艺简单、方便，原材料材料来源广泛，方便购买等优点。
