Abstract

This paper presents a comprehensive experimental program on the development of ductile, sustainable, and low-cost TRC composites for structural or repair applications. For this purpose, a range of ternary and quaternary blended cement mixes made of Ordinary Portland Cement, Fly Ash, Limestone and Silica Fume (with 70% to 80% cement replacement levels) with a target compressive strength of 30 MPa and a slump of > 300 mm were developed. The most suitable mixes were then used for the development of AR-glass-based TRCs with and without the addition of 2% PP, AR-glass and PVA short fibres. The performance of the developed TRCs was investigated in terms of cost, sustainability, flexural behaviour, bond behaviour, drying shrinkage and compressive strength. The results showed that the developed TRCs show a significantly higher flexural strength and deformation capacity while having a lower drying shrinkage, cost and environmental impact than those available in the literature.
