Abstract

Glass powder of various particle sizes (2, 5, 10 and 15 μm) has been assessed as a possible cement substitute for mortars. Different replacement rates of cement (5%, 10%, 15%, and 20%) have been considered for all particle sizes. The accessible porosity, compressive strength, gas permeability and microstructure have been investigated accordingly. The results have shown that adding glass powder up to 20% has a significantly negative effect on the porosity and compressive strength of mortar. The compressive strength initially rises with a 5% replacement and then decreases. Similarly, the gas permeability of the mortar displays a non-monotonic behavior; first, it decreases and then it grows with an increase in the glass powder content and particle size. The porosity and gas permeability attain a minimum for a 5% content and 10 μm particle size. Application of a Nuclear magnetic resonance (NMR) technique has revealed that incorporating waste glass powder with a certain fineness can reduce the pore size and the number of pores of the mortar. Compared with the control mortar, the pore volume of the waste glass mortar with 5% and 10 μm particle size is significantly reduced. When cement is partially replaced by glass powder with a particle size of 10 μm and a 5% percentage, the penetration resistance and compressive strength of the mortar are significantly improved.
