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.

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.

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.

The results show that latex modification has improved the mechanical properties of cement mortars, particularly their flexural strength.
