Experimental study on influence of aggregate gradation on properties of silica aerogel-glazed hollow beads composite insulation mortar

Taking the defects of narrow range particle gradation glazed hollow beads and low mechanical strength silica aerogel into consideration, bead have been mixed for composite aggregate insulation mortar. Some measures, such as gradation, were taken to optimize properties formulation, analyzing kinds factors that influence on mortar thoroughly, properties, thermal fire-resistance properties. Under condition 60vol% content, it was found compositing 35vol% 65vol% optimum producing samples with suitable
