Abstract The effect of using waste glass with ceramic as partial replacement of fine aggregate on C30 concrete”. Concrete is a heterogeneous mixture composed of different ingredients such as cement, fine aggregate, coarse aggregate, water, and admixtures if needed. The concrete industry is helping the environment by using wastes and by-products in concrete mixes and considering these materials as resource materials. Modern specifications for cement and concrete are performance-based and allow the producers to choose appropriate concrete-making materials and mix compositions to produce concrete mixes to meet the specification requirements. In the construction industry and factories, waste ceramic and glass might be dangerous and have a detrimental effect because the wastes are non-degradable and consume fertile and usable land. To overcome the problems encountered by waste ceramic and glass, recycling those wastes into usable things is better to minimize the problems above. This study was discussed experimental results about the effects of partially incorporating waste ceramic tile combined with waste glass to partially replace fine aggregate in concrete production. Different tests such as fine aggregate and fresh and hardened concrete tests have been undertaken to investigate the effect of waste ceramic and glass as a partial replacement of fine aggregate in concrete production. In this study, crushed ceramic tile commonly replaces fine aggregate with 30% in all mixes, whereas crushed glass partially replaced fine aggregate at various percentages of 5%, 10%, 15%, 20%, and 25%. Seven different concrete mixes were cast. Each test result was taken by taking the average of three specimens. The study result shows a decrease in slump value as the percentage of waste ceramic and glass increases, and compressive strength and tensile strength decrease below the control mix to some extent and increase as its strength as glass percentage increases. The maximum strength was achieved at M6, 30% ceramic, and 25% glass yielding 45.23 MPa. Thus, depending on this study, partially replacing fine aggregate using 30% crushed ceramic and 25% crushed glass was the optimum percentage yielding maximum strength.
