Ultrahigh-toughness marble-imitated ultrahigh-performance concrete and preparation method thereof
The invention relates to the field of building materials, and particularly discloses ultra-high-toughness marble-imitated ultra-high-performance concrete and a preparation method thereof. According to the prepared ultra-high-performance concrete with ultra-high toughness, marble-imitated material and white system, the metakaolin is used as a synergistic dispersion matrix, the nano-scale cellulose fibers are fully dispersed in the matrix, the performance advantages of the nano-scale cellulose fibers can be fully played through the method, the agglomeration problem of nano-scale cellulose is solved, and the super-high-performance concrete with the ultra-high toughness, marble-imitated material and white system is obtained. The homogeneity of the concrete is improved. The bridging effect of the nanoscale cellulose fibers is more effectively exerted, so that the breaking strength and the toughness of the ultra-high performance concrete are greatly improved. The used synergistic dispersion metakaolin is white, the color of the concrete is not influenced after the metakaolin is doped, the prepared concrete is highly similar to marble, and the surface of the concrete is free of pores and defects. The application can effectively supplement application deficiency of a white ultra-high performance concrete synergistic dispersion system.
本发明涉及建筑材料领域，具体公开了一种超高韧性仿大理石超高性能混凝土及其制备方法。本发明制备的一种超高韧性、仿大理石材质、白色体系的超高性能混凝土，以偏高岭土为协同分散基体，将纳米级纤维素纤维充分分散于该基体中，通过该方法，可充分发挥米级纤维素纤维的性能优势，解决纳米级纤维素的团聚问题，提高混凝土的均质性。更加有效发挥纳米级纤维素纤维的“桥连”作用，进而大幅提高超高性能混凝土的抗折强度和韧性。且使用的协同分散体偏高岭土为白色，掺入后不影响混凝土的颜色，制备的混凝土与大理石高度相似，且表面无气孔、缺陷。该申请可有效补充白色超高性能混凝土协同分散体系的应用缺失。
