Due to the day by day innovations and development in the construction field, the use of natural aggregates is very high and at the same time production of solid wastes from the demolitions of constructions is also very high. Because of these reasons the reuse of demolished constructional wastes came into the picture to reduce the solid waste and to reduce the scarcity of natural aggregates. Crushed waste Mangalore tiles are used as a replacement to the coarse aggregates. The waste crushed tiles were replaced in place of coarse aggregates by 100% without changing the mix design. M20 grade of concrete was designed to prepare the conventional mix. An experimental investigation like Compressive strength test and Water absorption test for concrete mixes with hundred percentages of waste crushed after 7, 14 and 28 days curing period. Variations in the workability for these different mixes were studied and observed that, an increase in the percentage of replacement of crushed Mangalore tiles.

Due to the day by day innovations and development in construction field, the use of
natural aggregates is very high and at the same time production of solid wastes from
the demolitions of constructions is also very high. Because of these reasons the reuse
of demolished constructional wastes came into the picture to reduce the solid waste
and to reduce the scarcity of natural aggregates. Crushed waste Mangalore tiles are
used as a replacement to the coarse aggregates. The waste crushed tiles were replaced
in place of coarse aggregates by 100% without changing the mix design. M20 grade
of concrete was designed to prepare the conventional mix. Experimental investigation
like Compressive strength test and Water absorption test for concrete mixes with
hundred percentages of waste crushed after 7, 14 and 28 days curing period.
Variations in the workability for these different mixes were studied and observed that,
increase in the percentage of replacement of crushed Mangalore tiles.
