High-toughness anti-freezing concrete block for high-altitude infrastructure engineering and preparation method of high-toughness anti-freezing concrete block
The invention relates to the field of high-altitude infrastructure engineering, and discloses a high-toughness anti-freezing concrete block for high-altitude infrastructure engineering and a preparation method of the high-toughness anti-freezing concrete block. The preparation method of the concrete block comprises the following steps: preparing the modified rubber basalt fiber and the modified basalt ore sand; after cement and a water reducing agent are fully mixed, mixing water is added for continuous mixing to an obvious adhesive state, then river sand and modified basalt ore sand are added for mixing to prepare mortar, a thickening agent is added into the mortar for adjusting the consistency of the mortar, then modified rubber basalt fibers are added into the mortar for uniform mixing, and concrete slurry is prepared; and molding the concrete slurry to obtain the high-toughness anti-freezing concrete block for the high-altitude infrastructure project. Orthogonal test design and analysis and mix proportion optimization are carried out, the concrete optimal mix proportion with the optimal bending strength and bending toughness index is obtained, and the toughness of the concrete block is further improved.
本发明涉及高海拔基建工程领域，公开了一种高海拔基建工程用高韧性抗冻混凝土砌块及其制备方法。所述混凝土砌块的制备方法包括：制备改性橡胶玄武岩纤维、改性玄武岩矿砂；将水泥、减水剂充分混合后，加入拌合水持续混合至明显胶粘状态，然后加入河砂、改性玄武岩矿砂混合制得砂浆，将增稠剂加入砂浆中调整砂浆稠度，再将改性橡胶玄武岩纤维加入砂浆中混合均匀，制到混凝土浆料；将混凝土浆料成型，即得高海拔基建工程用高韧性抗冻混凝土砌块。本发明进行正交试验设计和分析以及配合比优化，得到了具有最佳抗弯强度和弯曲韧性指数的混凝土最优配合比，进一步提高了混凝土砌块的韧性。
