e-GRC是对混凝土行业的一项很重要的和最新的贡献,代表纳米技术在GRC中的第三次成功应用,从而使其他的常用建材难以与GRC相媲美。当一种材料的颗粒尺寸降低至纳米级时,往往可出现新的性能或者增进其原有的性能。二氧化钛纳米粒子的典型特性是,即使它与水泥相混合仍然具有光触媒活性,使水泥基材料的外表面有强光触媒效应,从而通过“去污”作用而使之呈现相当好的外观,并显著降低周围空气中污染物的浓度。
e-GRC is a significant and recent contribution to the concrete industry and represents the third successful application of nanotechnology in GRC, making it difficult for other commonly used building materials to compete with GRC. When the particle size of a material is reduced to nano-scale, new properties can often appear or enhance its original properties. Titanium dioxide nanoparticles are typically characterized by their photocatalytic activity even when they are mixed with cement to provide a strong photocatalyst effect on the outer surface of the cementitious material to give it a fairly good appearance by “decontamination” and Significantly reduce the concentration of pollutants in the surrounding air.
