ABSTRACTIn the study, the textile wastes consist of polyster and viscose taken from the textile and apparel manufacturers. These wastes were cut into 2 to 6cm lengths and mixed with Portland cement according to the textile-to-cement ratio of 1%,2%,3% and 4% by the cement weight. Water was added corresponding to 0.40 water-to-cement ratio. The composites were cured in water and then tested for compressive, flexural and split tensile strength test at the age of 3, 7 and 28 days respectively. Upto 3% of textile waste give more split tensile strength and flexural strength compare to conventional concrete.

INTRODUCTIONConcrete is one of the most widely used construction material in the world. It can be cast in diverse shapes. Concrete is a composite material formed by the combination of cement, sand, coarse aggregate and water in a particular proportion in such a way that concrete produced meet the needs as regards its workability, strength, durability and economy. Although fabric wastes are commonly recycled into practical goods, they do not stay usable long enough before they return to being wastes once again.

This is a big drawback since the price of raw materials such as cotton and the cost of processing textiles are very expensive. Hence, implementing textiles as part of building material are most welcome especially in this era when waste recycling is the most discussed issue world-wide. This will not only minimize the total amount of textile waste being dumped in the landfill. But will also eliminate the pollution threats exposed by the process.

OBJECTIVESThe objectives of this research are as stated below: To utilize textile waste as cementitious composites To evaluate the Physical properties of textile waste cementitious composites To suggest suitable applications of textile waste cementitious composites To study the strength of composite concrete by the adding fabric.To compare the results made of composite concrete with conventional concrete.

RESULTCompressive strength of cube has increase up to 2% with the addition of textile waste.Flexural strength of prism has increase up to 3% with the addition of textile waste.Split tensile strength of cylinder has increase up to 3% with the addition of textile waste.

CONCLUSIONThe concrete ingredients such as cement, fine aggregate & coarse aggregates chemical and physical properties was successfully studied.Textile waste in the concrete generally increases the strength of the concreteThe compressive strength, flexural strength and split tensile strength test of concrete at 3,7 and 28 days has determined and discussed.When we increase the addition of textile waste the volume of concrete also increases and accupies more space and hence the strength of the concrete decreases.
