Phosphogypsum micro-expansion lightweight aggregate ultra-high performance concrete and preparation method thereof
The invention belongs to the technical field of building materials, and discloses ardealite micro-expansive lightweight aggregate ultra-high performance concrete and a preparation method thereof.The ardealite micro-expansive lightweight aggregate ultra-high performance concrete is prepared from 600-750 kg/m < 3 > of cement, 150-200 kg/m < 3 > of fly ash microbeads, 150-200 kg/m < 3 > of silica fume, 550-700 kg/m < 3 > of ardealite micro-expansive lightweight aggregate, 300-350 kg/m < 3 > of quartz sand aggregate and 3-6 kg/m < 3 > of temperature sensitive fibers. 20-30 kg/m < 3 > of fine copper-plated short steel fibers, 20-30 kg/m < 3 > of a water reducing agent and 150-200 kg/m < 3 According to the invention, high-valued application of the phosphogypsum in the ultra-high performance concrete is realized, and the problem that the mechanical property and the structural stability of the ultra-high performance concrete are reduced is solved while light weight of the ultra-high performance concrete is realized.
本发明属于建筑材料技术领域，公开了一种磷石膏微膨胀轻骨料超高性能混凝土及其制备方法，该磷石膏微膨胀轻骨料超高性能混凝土，包括以下原料：水泥600～750kg/m3，粉煤灰微珠150～200kg/m3，硅灰150～200kg/m3，磷石膏微膨胀轻骨料550～700kg/m3，石英砂集料300～350kg/m3，温度敏感型纤维3～6kg/m3，微细镀铜短钢纤维20～30kg/m3，减水剂20～30kg/m3，水150～200kg/m3。本发明不仅实现了磷石膏在超高性能混凝土中的高值化应用，而且在实现超高性能混凝土轻质化的同时，解决了其力学性能和结构稳定性下降的问题。
