In the recent years,there has been an increasing demand for castable refractories that can be produced with less energy and equipment.Along with the decrease in the proportion of cement,which serves as the hydraulic binder in low and ultra-low-cement refractory concretes and thus,an according reduction in the amount of CaO in a mixture,thermomechanical properties have improved and therefore these have become the mostly preferred class among castable refractories.Low and ultra-low cement castables are mainly used in high temperature applications
近年来,人们已经越来越要求耐火浇注料可以生产出足够的能量较小,和设备.随着比例减少水泥,作为低,ultra-low-cement液压粘结剂耐火混凝土,由此降低了相应的金额混合物,中氧化钙的热力性能有长足的进步,因此,这已成为最优先阶级在浇注料耐火材料.低水泥浇注超低的主要是应用在高温应用
