The high-strength concrete is prepared from the following components in parts by weight: 180-200 parts of ordinary Portland cement, 100-200 parts of silica sand, 40-80 parts of modified bamboo fiber, 60-100 parts of basalt fiber, 200-240 parts of an active admixture, 6-10 parts of a water reducing agent, 8-12 parts of a preservative, 4-8 parts of a slow-release alkali agent and 180-200 parts of water, wherein the outer surface of the high-strength concrete is provided with an erosion isolating medium. The invention belongs to the technical field of concrete preparation, and particularly provides high-strength concrete and a preparation process thereof, and the high-strength concrete can prevent steel bars from being corroded by adding a preservative, so that the performance degradation and failure of a concrete structure are slowed down, and the strength of the concrete is improved.
本发明公开了一种高强度混凝土及其制备工艺，包括如下重量份数的组分：普通硅酸盐水泥180‑200份，硅砂100‑200份，改性竹纤维40‑80份，玄武岩纤维60‑100份，活性掺合料200‑240份，减水剂6‑10份，防腐剂8‑12份，缓释碱剂4‑8份，水180‑200份，所述高强度混凝外表面具有隔断侵蚀介质。本发明属于混凝土制备的技术领域，具体是提供了一种通过加入防腐剂，防止钢筋被腐蚀，从而减缓混凝土结构性能的退化和失效，提高混凝土的强度的高强度混凝土及其制备工艺。
