Abstract - The construction industry is increasingly seeking
Fly ash is a fine powder that is a by-product of burning coal in power plants. It is made up of the non combustible parts of coal and a small amount of carbon that remains from incomplete combustion. Fly ash is usually light tan in color and consist mostly of glassy spheres that are silt-sized and clay-sized.
sustainable alternatives to traditional building materials to mitigate environmental impact. This study investigates the feasibility of partially replacing conventional aggregates in concrete with Mangalore tiles, fly ash, and cement alternatives. The aim is to develop a more environmentally friendly and resource efficient concrete mix without compromising structural integrity.
Overall, this experimental study provide insights into the feasibility and effectiveness of utilizing fly ash and mangalore tiles as partial replacements for cement, fine and coarse aggregate in concrete production. The findings of this research could potentially contribute to the development of sustainable construction practices, reducing the environmental impact associated with conventional concrete production while maintaining or improving the performance of concrete structures.
The study also investigates the impact of Mangalore tiles as a partial replacement for coarse aggregates, considering their lightweight and unique thermal properties. Fly ash, a byproduct of coal combustion, is explored as a supplementary cementitious material to reduce the dependency on traditional Portland cement, thereby lowering carbon emissions associated with concrete production.
This paper deals with experimental study on the compressive strength and split tensile strength of M25 grade concrete with the partial replacement of fine and coarse aggregate by using Mangalore tiles. The sample are casted with fine aggregate 3% , 6% , 9% and 12% replacement and coarse aggregate 20% replacement and also partial replacement cement by fly ash 20% tested for 7 and 28 days strength with proper curing. The results show that upto 9% replacement level of fine aggregate attained workable concrete with satisfactory strength.
Important aspects of the work is to strengthen the concrete economically for structural applications by decreasing the aggregate content.
Key Words Mangalore Tiles , Fly Ash , Chemical Admixture , Replacement material , Compressive Strength , Split Tensile Strength , Flexural Strength.
1. INTRODUCTION
The use of more and more concrete in construction not only results in scarcity of materials but also turns out to be expensive. One such approach involves the Partially Replacing Mangalore Tiles and Flyash, Cement in Concrete , respectively. There are nearly 74 tile factories in the whole Dakshina Kannada district producing about 6000 patented Mangalore roof tiles per factory per day, out of which about 2% results as wastage. Coarse aggregates which occupy nearly 70 to 75% volume of concrete are sometimes referred as ingredients in more than one sense. Aggregates are in general cheaper than cement and impart greater volume stability and durability to concrete.

Experimental Objectives
This work demonstrates the suitability of Mangalore tiles and fly ash as partially replacement of aggregates in concrete. Studying the behavior of concrete, replacing cement by fly ash in different replacement percentage to get optimum results and using it for M25 grade of concrete. Same done for fine and coarse aggregate replacing Mangalore tiles. Studying the cost analysis of conventional concrete and proposed concrete with the respective grade of concrete. To contribute to the conservation of natural resources by utilizing a waste byproduct in construction materials.
2. LITERATURE REVIEW Sivan Balasubramaniam.T.R. et_al (2018) : Have used mangalore tiles waste as coarse aggregate in concrete. Here they have used Fly ash as partially replacement to Ordinary Portland Cement. And compressive Strength and 15% the compressive strength has got increased. test (18.66 N/mm2 and 31.44 N/mm2 at 7 and 28 days) Split tensile strength test (3.02 N/mm2 and 3.92 N/mm2 at 7 and 28 days)
