High-strength concrete and preparation process thereof
The invention relates to the technical field of concrete, in particular to high-strength concrete and a preparation process thereof. According to the preparation method, 1, 7-dibromoheptane, cyanobiphenol, hexadecanol and 1-ethyl-2-methylimidazole are taken as main raw materials, and the nucleating agent is obtained. Adding the nucleating agent into a cellulose solution, spinning and extruding, and physically mixing with the high-strength fiber to obtain the high-strength fiber. Dipping the high-strength fiber into the mixed solution obtained by adding the modified nano titanium dioxide, and drying to obtain the composite fiber. And taking methyl allyl polyoxyethylene ether, pyromellitic acid, methoxy polyethylene glycol, methacrylic acid and the like as main raw materials to obtain the polycarboxylate superplasticizer. Finally, cement, slag powder, a silane coupling agent YDH171, coarse aggregate, a polycarboxylate superplasticizer, the composite fibers and water are mixed to obtain a mixed material, and the mixed material is subjected to die filling and curing to obtain a finished product. The finished product obtained by the invention has good ultraviolet aging resistance and mechanical strength, thereby having wide application prospects.
本发明涉及混凝土技术领域，具体是一种高强度混凝土及其制备工艺。本发明以1,7‑二溴庚烷、氰基联苯酚、十六醇和1‑乙基‑2‑甲基咪唑为主原料，得到成核剂。再将该成核剂添加至纤维素溶液中，喷丝挤出、与高强纤维进行物理混合，得到高强纤维。再将高强纤维浸渍于添加改性纳米二氧化钛得到的混合液中，经烘干后得到复合纤维。再以甲基烯丙基聚氧乙烯醚、均苯四甲酸、甲氧基聚乙二醇、甲基丙烯酸等为主要原料，得到聚羧酸减水剂。最后将水泥、矿渣粉、硅烷偶联剂YDH171、粗骨料、聚羧酸减水剂、复合纤维和水混合得到混料，再经装模、养护，得到成品。本发明得到的成品具有良好的抗紫外老化性能和力学强度，因此具有广阔的应用前景。
