EXPERIMENTAL INVESTIGATION ON STRENGTHENING INTERLOCKING HOLLOW BLOCK WITH POLYESTER STRAP WASTE

Production of blocks used for wall construction have different techniques adopted which could be in form of hollow or solid blocks produced in varying shapes laid with mortar. An improved form of mortar-less blocks which is an innovative structural component for masonry building construction called interlocking block .This brings about economical production, reduced cost of labour and appreciation of available local materials for construction of structures for both rural and urban development in the world today, thereby eliminating the use of mortar in laying of blocks. The blocks are neatly fixed through the aid of grooves and protrusion on the blocks to restrain movement when assembling the interlocking block from top and or bottom of one to another forming safe, stable, economical and aesthetic bonding for walls. It can be widely used for both temporary and permanent structures. The assembling does not require much skill, and more so, faster, neater with improved efficiency. The dismantling in the case of temporary wall is also, easier, faster and economical which do not involve destroying any part of the wall. Now days, hollow concrete blocks and bricks are becoming very popular. These blocks are being widely used in construction of residential buildings, factories and multi-storied buildings. These hollow blocks are commonly used in compound walls due to its low cost. The blocks and bricks are made out of mixture of cement, crusher powder and stone chips. By adding polyester strap waste of 0.1to 0.12% we can increase the strength of hollow concrete block Hollow blocks construction provides facilities for concealing electrical conduit, water and soil pipes. It saves cement in masonry work, bringing down cost of construction considerably
