WebDuring the mortar mixture, a homogeneous mixture is obtained which covers the surface of the perlite grains. It creates micro air bubbles in cement mortar and reduces cement consumption. Thanks to micro air bubbles, it increases the thermal insulation values of perlite concrete and facilitates its processing. WebJun 13, 2024 · The mixture with 30% expanded perlite presented a 1.58% higher density in a 0.9 kp/cm 2 vacuum index compared to that obtained in 0.7 kp/cm 2. For the mixture with 20% expanded perlite in the mass, the density increase in the respective vacuum index values was 2.85% and for 100% clay material this increase was 4.1%.
