Abstract :

The concrete is a cement-based material which has become most popular and widely used in construction field such as highways, flyovers, buildings, dams etc. Now a days the consumption of concrete increased exponentially and structure without concrete cannot be imagined. Durability of concrete mainly depends upon the climatic condition which may likely to damage the concrete structures. To enhance the life against such problems it is necessary to improve the mechanical properties of the concrete. The use of pozzolanic in concrete and mortar was started with a view to reduce the cost, overcome the adverse effects of OPC and utilize waste products and by products of industrial activities which were providing harmful to environment, natural resources etc. Also, the use of pozzolanas improves several properties of mortar and concrete viz. workability, strength, resistance to cracks permeability and durability. Further the use of pozzolanas has resulted in the production of high- performance concrete. Owing to globalization, privatization and liberalization, the construction of important infrastructure projects are increasing in developing countries like India. Such development activities require large quantities of natural resources. This leads to faster depletion of natural resources on one side and manifold increase in cost of construction of structures on the other side, which is a major problem in construction sector today. In view of this people have started searching for suitable alternate materials which can be used either as an additive or as a partial replacement to conventional ingredients of concrete. Use of tile dust as partial replacement for cement in concrete is one such economical method. In the laboratory tests were conducted by partially replacing cement in concrete by tile dust as 0%, 10%, 20%, 30%, 40% & 50%. The development of compressive strength, split tensile strength and flexural strength of concrete at the age of 7, 28, 56 days are investigated. These strengths are compared with conventional concrete of the same mix proportions.
