Concrete based on co-doped hybrid fibers and production process thereof
The invention relates to the technical field of concrete, in particular to concrete based on co-doped hybrid fibers and a production process of the concrete. The concrete is prepared from the following raw materials in parts by weight: 480 to 550 parts of Portland cement, 200 to 230 parts of fly ash, 800 to 1000 parts of gravel, 1000 to 1100 parts of sand, 200 to 280 parts of expanded perlite, 20 to 30 parts of nano titanium dioxide, 40 to 70 parts of wollastonite, 25 to 40 parts of kaolin, 15 to 25 parts of carbide slag powder, 30 to 50 parts of composite fiber, 6 to 10 parts of functional additive, 15 to 25 parts of silane coupling agent, 5 to 10 parts of water reducing agent and 260 to 300 parts of water. Wherein the composite fiber is formed by mixing modified basalt fiber and modified polyvinyl alcohol fiber according to the ratio of (1-1.5): 1; the concrete produced by the invention not only has excellent mechanical properties, but also has very good corrosion resistance, and the service life of the concrete is prolonged to a certain extent while the quality of the concrete is ensured.
本发明涉及混凝土技术领域，具体为一种基于复掺混杂纤维的混凝土及其生产工艺；所述混凝土由如下重量份原料组成：480～550份硅酸盐水泥、200～230份粉煤灰、800～1000份碎石、1000～1100份砂、200～280份膨胀珍珠岩、20～30份纳米二氧化钛、40～70份硅灰石、25～40份高岭土、15～25份电石渣粉、30～50份复合纤维、6～10份功能助剂、15～25份硅烷偶联剂、5～10份减水剂及260～300份水；其中，所述复合纤维由改性玄武岩纤维及改性聚乙烯醇纤维按1～1.5：1混合而成；本发明所生产的混凝土不仅具有优良的力学性能，还具有很好的抗腐蚀性能，保证了混凝土质量或品质的同时也在一定程度上延长了其使用寿命。
