Research on the Influence of Additive Quantity on Properties of Silica Aerogels/Glazed Hollow Beads Composite Thermal-insulating Mortar

Abstract

The effects of the content of fly ash, redispersible latex powder and methyl cellulose on the properties of thermal insulation mortar were studied. The results showed that the incorporation of fly ash was beneficial to the mechanical properties and pore structure of hardened paste; redispersible emulsion powder improved the workability of thermal insulation mortar, and enhanced the bonding force between inorganic cementitious material and lightweight aggregate; methyl cellulose significantly reduced the dry density of thermal insulation mortar.
