Cost-effective concrete using superplasticiser and partial replacement of crushed stone with brick chips

Key Points

• The aim is to determine the effectiveness of using superplasticisers and brick chips in concrete for cost reduction.
• Evaluated different mixes of concrete incorporating superplasticisers and varying proportions of brick chips as a replacement for crushed stone.
• Conducted strength tests to analyze the mechanical properties of the modified concrete against standard concrete.
• Concrete with 20% brick chip replacement showed similar compressive strength (30 MPa, p<0.05) compared to conventional concrete.
• Cost savings of 15% were observed when using modified concrete mixes, enhancing economic feasibility.
