Waste glass as a replacement for fine fraction in high-performance concrete

Abstract

Research project is focused on the experimental verification of high-performance concrete (HPC) with full replacement of fine fraction. This paper deals with HPC mixtures containing recycled glass materials (waste glass powder from municipal waste, waste glass powder from photovoltaic panels, grinding waste glass from jewellery). The research is based on the results of previous student grant. A recipe that was made during 2017 is used and optimized according to the waste glass powder properties. The influence of different local sources is monitored. The HPC mixtures are tested for mechanical properties (flexural strength, compressive strength) and compared with the results from the previous research. Flowability is tested and all the mixtures are workable. The mixture with grinding glass (GG) showed the highest results in flexural and compressive strength compared to the reference sample, the use as a substitute for fine fraction in HPC is conceivably attitude. The municipal waste glass mixture and the mixture with the waste glass from photovoltaic panels is not usable as HPC.
