AN EXPERIMENTAL STUDY ON THE USE OF RECYCLED AGGREGATES IN RIGID PAVEMENT (KEY IJP************443)
Concrete is one of the most widely used construction materials in the world, mainly due to its favorable features such as durability, versatility, satisfactory compressive strength, cost effectiveness. But with the depleting natural resources and the huge amount of concrete waste produced, it becomes essential to identify an effective way to solve the need of the moment. In this rapid industrialized world, recycling construction material plays an important role to preserve the natural resources. In this research, Recycled Coarse Aggregates (RCA) from demolished slab pieces was used. These demolished slab pieces are crushed to suitable size and reused as recycled coarse aggregate. Natural sand used as fine aggregate. Concrete industry, uses 12.6 billion tons of raw materials each year, is the largest user of natural resources in the world. The environmental impact of production of raw ingredients of concrete (such as cement and coarse and fine aggregates) is considerable. In this paper The mix design has been done by trial and error method. The mix proportions are calculated as per IS code. The design procedure as per IS code and IRC: 44-2008 is used in mix design of M30 grade cement concrete. The wc ratio is taken 0.5% for all the mixes. Hence, Coarse aggregates was replaced in percentages of 0%, 20%, 40 %, 60 %, 80 %, 100 % with recycled coarse aggregates 150 150 150mm, Beam and Cylinder moulds were used for casting.
