Abstract: In this study mechanical properties and permeability of cement mortar produced with waste
glass powder (WGP) were investigated up to 28 days by means of destructive and non-
destructive test methods to evaluate the pozzolanic activity of WGP. Particle size distribution
and chemical composition of WGP were determined and found to be comparable to the
commonly used cementitious materials. Standard mortar specimens (RM) were cast with
Portland cement (CEM I 42.5R) in addition to WGP mortar specimens incorporated with 5%
(GP1), 10% (GP2), 15% (GP3) and 20% (GP4) WGP by weight as cement replacement. Water
reducing admixture was added to obtain a flow of 160±10 mm in 25 drops. Isothermal
calorimetry, setting time, compressive strength, flexural strength, capillary water absorption
and chloride migration tests were performed and results were compared with ultrasonic wave
speed and surface resistivity measurements. In general, use of WGP up to 15% has no
significant effect on the development of compressive strength, ultrasonic wave speed and
surface resistivity, and the results were comparable with the standard mortar specimens.
Replacement 20% of cement exhibited inadequate strength, especially at early ages; however,
considering the reduced impact on the environment by less accumulation of waste and increased
natural resource preservation, using WGP at high levels might be beneficial. Future studies
focusing on improving the general performance of WGP mixtures with larger amount of cement
replacement (>GP4) and testing for longer periods will be invaluable.
