AN INVESTIGATION ON STRENGTH CHARACTERISTIC OF CONCRETE CONTAINING RECYCLED AGGREGATES OF MARBLE WASTE

The results obtained from the present investigation on strength characteristics of concrete containing natural aggregates and natural aggregates with partial replacement by marble waste aggregates in different percentages have been presented. Various specimens were cast and tested .The cubes were used to determine compressive strength, cylinder for determining split tensile strength and beams were cast to determine flexural strength. In the series of test conducted when natural aggregates were replaced by marble waste aggregates in percentages varyinf from 10% to 40% and the effect of replacement on the compressive strength, split tensile strength and flexural strength were observed. The compressive strength, split tensile strength and flexural strength of specimens were tested for mixes containing marble waste recycled aggregates increased for replacement upto 30%. However for the 40% replacement of marble waste aggregate with natural aggregate a marginal decrease in compressive, split and flexural strength is recorded. Therefore it can be concluded that the production of concrete of normal strength is feasible and viable by replacing the natural aggregates by the marble waste aggregates without compromising the strength characteristics.
