High-strength anticorrosive concrete and preparation process thereof
The invention relates to high-strength anticorrosive concrete and a preparation process thereof, and relates to the technical field of concrete preparation. The high-strength anticorrosive concrete comprises the following raw materials by weight: 180-200 parts of ordinary Portland cement; 1180-1220 parts of a coarse aggregate; 600-640 parts of a fine aggregate; 200-240 parts of an active admixture; 6-10 parts of a polycarboxylate superplasticizer; 8-12 parts of a preservative; 4-8 parts of a slow-release alkaline agent; 180-200 parts of water. The preservative is added to prevent the steel bars from being corroded, thereby slowing down the degradation and failure of the concrete structure performance and enhancing the strength of the concrete.
本发明涉及一种高强度防腐混凝土及其制备工艺，涉及混凝土制备的技术领域，其包括以下重量份计原料：普通硅酸盐水泥180‑200份；粗集料1180‑1220份；细集料600‑640份；活性掺合料200‑240份；聚羧酸减水剂6‑10份；防腐剂8‑12份；缓释碱剂4‑8份；水180‑200份。通过加入有防腐剂，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。
