Mechanical properties of hybrid fibre reinforced quaternary concrete
Abstract
Quaternary blending cement concrete with fibres is studied in terms of compressive, split tensile, and flexural strength properties, and impact resistance. Fly ash, rice husk ash, and limestone powder, are used as partial replacement of cement. Steel, carbon, and polypropylene fibres, are used in different fractions. The results show that the steel-carbon and steel-carbon-polypropylene hybrid fibre reinforced concretes perform better with regard to compressive, split tensile, and flexural strength properties, and impact resistance.
