Abstract

Reinforced concrete slabs are designed as per limit state of serviceability to ensure its performance not degrading till it's service life. However, the durability of the structure is not ensured with design, it largely depends on quality of materials and work. The aim of this paper is to address those serviceability issues like cracking, excessive deflections, concrete spelling, etc. In this paper, RCC slabs of dimension 35cmx35cm is casted with M25 grade of concrete and are retrofitted with two types of wire meshes viz. Chicken wire mesh and sieve wire mesh. The prepared specimen is tested in universal testing machine, supports are given by I beams and point load is applied at the centroid of top surface. Similarly, retrofitted slabs are tested in the Same set up. The results showed that slab retrofitted with chicken wire mesh and sieve wire mesh showed good performance.
