Abstract

This research aims to study the properties of mortars containing car broken glass at 0, 10, 20, 30, 40, 50, 60, 80, and 100% by volume. The physical, mechanical, and thermal properties of mortars were studied. The test results showed that the use of car broken glass to replace natural sand had no effect on the workability, compressive strength, porosity, water absorption, density, and ultrasonic pulse velocity of mortars. This was due to the similar size distribution of car broken glass and natural sand. The thermal conductivity coefficient significantly decreased with the increasing of car broken glass contents. This result pointed out that the car broken glass exhibited thermal insulating property. The developed mortars containing car broken glass in this study were appropriate for use as thermal insulating composites in construction and building materials.
