UHPC suitable for long-term sewage environment and preparation process thereof
The invention provides UHPC suitable for a long-term sewage environment and a preparation process thereof. The UHPC comprises the following components: water, cement, fine aggregate, a mineral admixture, metal fibers, an additive and an antibacterial agent, wherein the antibacterial agent is beta-type phthalocyanine blue with a particle size of 0.005-0.015 [mu]m, and the cement is a mixture of ordinary Portland cement and calcium aluminate cement. According to the invention, the antibacterial agent phthalocyanine blue matched with UHPC is creatively introduced, and the high performance of the UHPC is combined, so that the material has good biological corrosion resistance, and the flowability and the strength of the material are improved; part of calcium aluminate cement is used for replacing ordinary Portland cement, so that the UHPC has a relatively low biological erosion rate, and the erosion-resistant period of the UHPC is further prolonged; and the UHPC is more suitable for serving under the working condition of sewage and waste treatment, the corrosion resistance of components can be greatly improved, the service life of the structure is prolonged, the later maintenance cost is reduced, and the UHPC has wide market prospects.
本发明提供了一种适用于长期污水环境下的UHPC及其制备工艺，该UHPC的组分包括水、水泥、细骨料、矿物掺合料、金属纤维、外加剂和抗菌剂；其中抗菌剂是粒径为0.005～0.015μm的β型酞菁蓝，水泥为普通硅酸盐水泥和铝酸钙水泥的混合物。本发明创造性的引入与UHPC相匹配的抗菌剂酞菁蓝，结合UHPC的高性能，使其具有良好的抵抗生物腐蚀的性能，同时提高其流动性和强度；使用部分铝酸钙水泥代替普通硅酸盐水泥，使得UHPC具有较低的生物侵蚀速率，进一步提高其耐侵蚀的期限。本发明的UHPC更适合在污废处理工况下服役，可大大提高构件耐各种腐蚀的性能，延长结构使用寿命，降低后期维护成本，有广阔的市场前景。
