The invention discloses acid and alkali corrosion resistant concrete for tunnel construction and a preparation method of the acid and alkali corrosion resistant concrete. The acid and alkali corrosion resistant concrete comprises the following components in parts by weight: 120-140 parts of water, 100-120 parts of cement, 80-90 parts of kaolin, 30-50 parts of a fiber mixture, 35-45 parts of porous microspheres, 30-40 parts of coarse aggregate, 30-40 parts of fine aggregate and 30-40 parts of silica fume. By arranging water, cement, kaolin, a fiber mixture, porous microspheres, coarse aggregate, fine aggregate and silica fume, the strength and acid and alkali resistance of the concrete can be enhanced through the fiber mixture, and by arranging the porous microspheres, the weight per unit area of the concrete can be reduced while the strength of the concrete is ensured. Finally, the concrete has good impact resistance and acid and alkali resistance.
本发明公开了一种用于隧道施工的耐酸碱侵蚀的混凝土及其制备方法，包括以下重量份组分：水120‑140份，水泥100‑120份，高岭土80‑90份，纤维混合物30‑50份，多孔微珠35‑45份，粗骨料30‑40份，细骨料30‑40份，硅灰30‑40份。本发明通过设置有水，水泥，高岭土，纤维混合物，多孔微珠，粗骨料，细骨料，硅灰，能够通过纤维混合物增强混凝土的强度以及耐酸碱性能，通过设置的多孔微珠，能够在保证混凝土强度的同时降低其单位面积的重量，最终使得混凝土具有良好的耐冲击性能以及耐酸碱性能。
