This experiment was conducted to determine the utility of substituting cement with the recycled glass powder (RGP) in mortar mixtures. A total of 21 mortar mixtures were produced using various RGP (FG) ratios (CG), and fly ash (FA) powders. The mortar mixtures were used to prepare cubes which were tested for 7-and 28-day compressive strength. The substitution of cement with FG and CG in mortar resulted in reduced 7-and 28-day compressive strength values. However, the amount and type of RGP substituted for cement plays a crucial role in the determination of mortar strength. Above contraction in compressive strength was observed at an initial maturity than at the final maturity. Further, replacement of cement with Fly Ash showed increase in compressive strength up to certain content. More research and testing for the optimal percentage and size of waste glass powder that can be used is required in flowable fill.

Engineered cementitious composite (ECC) is conventionally made up of high content fly ash (FA) combined with Portland cement (PC) as a binder. However, the growing call for sustainability is leading to continuous decommissioning of various coal power plants around the world thereby limiting the supply of fly ash available for ECC production. Therefore, it is of high importance to find alternative materials that can be incorporated into ECC as a partial replacement of the conventional binders. This experimental investigation was carried out to investigate the feasibility of incorporating glass powder (GP) as binder into ECC mixtures. The mechanical performance in terms of its compressive, tensile, and flexural properties was evaluated. Results from this study showed that 25% FA can be replaced with GP without any significant reduction in the mechanical performance of ECC mixtures. Microstructural investigations of the mixtures incorporating GP show good bonding between the cementitious matrix and the fibres.

This research examined the effect of mix proportions namely, water to cementitious (w/c) ratio and glass content, on the flowability and compressive strength of controlled low-strength (CLSM) mixtures. A total of 20 mixes containing different proportions of cement, sand, class C fly ash, coarser glass, finer glass and water were prepared and tested. Results showed that both flowability and strength are dependent on w/c ratio and type and percent of glass content. Strength of mixes containing high volume of coarser glass was found more sensitive towards w/c ratio. Further strength was found to improve with increase in finer portion of the glass powder. Density was also found to correlate well with the moisture content of CLSM specimens. Specimens with lower moisture content produced denser CLSM structure. The results of this study would be useful in establishing mix proportions for CLSM incorporating recycled glass, fly ash, sand and cement for commercial applications

The compounding of polyvinyl chloride (PVC) with two types of fillers and some additives were studied for the manufacturing of acid resistant tile. Various concentrations of two types of fillers namely; calcium carbonate and recycled glass powder were used along with different additives generally categorized as plasticizers, stabilizers, and lubricants were mixed in the standard concentration unit parts per hundred resins (phr) with the PVC as base polymer. The effects of filler materials on acid resistant towered different acids like sulphuric, nitric and hydrochloric at different concentration were studied. Samples which passed the test were further checked for dielectric strength and mechanical properties. It was found that the recycled glass powder is very suitable filler for preparing PVC composites materials for flooring tile, where most samples undergo negligible change in weight and maintained its shape and flexibility during the acid resistant test.

In order to value glass in the production of cement and concrete. We have verified the effect of the progressive substitution of 10% to 50% of the volume of cement by glass powder and silica fume on the mechanical properties of hardened mortars, we have also verified their inhibitory effect of the Alkali Silica Reaction (ASR) by studying the variation of mass, expansion, opening and density of cracks as well as the loss of mechanical performance of mortars undergoes a test that accelerates the ASR by autoclave. We have concluded that the use of these mineral admixtures can improve the mechanical performance of mortars, and it can reduce expansions and mechanical performance losses due to ASR.
