Concrete for tunnel anti-collision wall as well as preparation method and application of concrete
The invention relates to the technical field of concrete, and particularly discloses concrete for a tunnel anti-collision wall as well as a preparation method and application of the concrete. The concrete for the tunnel anti-collision wall is prepared from the following components: 180 to 220 parts of cement, 70 to 110 parts of a carbon mineralized mineral material, 10 to 15 parts of hollow glass beads, 1 to 1.6 parts of a foaming agent, 0.4 to 0.7 part of a foam stabilizer, 3 to 9 parts of a water reducing agent, 0.6 to 2 parts of fibers and 130 to 180 parts of mixing water, the preparation method of the carbon mineralized mineral material comprises the following steps: taking 100-300 parts by weight of mineral material and 10-50 parts by weight of water, injecting 20-100% CO2 at the flow rate of 1-3 L/min, and grinding for 20-60 minutes at the speed of 400-600 rpm; and drying to constant weight, smashing and sieving to obtain the traditional Chinese medicine composition. The concrete for the tunnel anti-collision wall has long-term stable collapse energy absorption, and is excellent in impact toughness and freeze-thaw resistance.
本申请涉及混凝土的技术领域，具体公开了一种隧道防撞墙用混凝土及其制备方法和应用。本申请的隧道防撞墙用混凝土包括以下组分：水泥180~220份、碳矿化矿物材料70~110份、空心玻璃微珠10~15份、发泡剂1~1.6份、稳泡剂0.4~0.7份、减水剂3~9份、纤维0.6~2份、拌合水130~180份；碳矿化矿物材料的制备方法为：取矿物材料共100~300重量份，水10~50重量份，注入20%~100%CO2，CO2流速为1~3L/min，以400~600rpm研磨20~60min；烘干至恒重，捣细过筛，即得。上述隧道防撞墙用混凝土具有长期稳定的溃缩吸能，且抗冲击韧性和抗冻融性能优异。
