In this work, leftover foundry sand and vermiculite were used as partial replacements for fine and coarse aggregates in hybrid fibre reinforced concrete (HFRC). The study also concentrated on HFRC mix percentage optimization to achieve desired attributes. By creating multiple HFRC mixtures with varied ratios of used foundry sand and vermiculite. The mechanical characteristics of the HFRC were assessed. Tests on the HFRC’s permeability, water absorption, and chloride ion penetration were used to evaluate its durability. In comparison to ordinary concrete, the study shows that adding foundry sand and vermiculite to HFRC increased its mechanical and durability attributes. It was discovered that HFRC has stronger compressive, splitting tensile, and flexural strengths than regular concrete. In comparison to conventional concrete, HFRC also showed less water absorption, permeability, and chloride ion penetration. The research also determined the HFRC mix ratio that produced the maximum flexural strength, splitting tensile strength, and compressive strength. Vermiculite made up 10% of the mix’s coarse aggregate replacement, while discarded foundry sand made up 20% of the mix’s fine aggregate replacement. Sustainable development now requires that waste materials be used in building. This study uses waste foundry sand (WFS) and vermiculite to assess the mechanical properties.
