Durability and flexibility characteristics of latex modified ferrocement in structural development applications

Purpose: The purpose of this paper is to discuss the durability and flexibility characteristics of latex modified ferrocement in comparison with conventional ferrocement particularly when exposed to severe environmental conditions. Design/methodology/approach: The research programme encompasses the laboratory investigation on the structural, the deformation behaviour and characteristic of latex modified ferrocement elements cured in air and salt-water environments. The tests include determination of load and deflection characteristics, moments, crack widths, crack spacing, and the number of cracks when subjected to static flexure. Findings: Test result indicates a significant improvement in reducing and bridging micro cracks, especially in the pre-peak load region. Fracture toughness and deformability increased significantly. However, the post peak behaviour was quite similar to conventional ferrocement. Originality/value: The results show that latex modification has improved the mechanical properties of cement mortars, particularly their flexural strength.
