Abstract
Concrete is the most widely used man made construction material. In the present study the recycled plastics were used to prepare concrete there by providing a sustainable option to deal with the plastic waste.
Experimental investigations were performed to study Fresh properties (slump and density) and mechanical properties (compressive strength, flexural strength, splitting tensile strength).
It is to conclude that Waste plastic can be effectively re-used without affecting the mechanical properties considerably (5- 10%). With increase in the percentage of plastic there has been a sudden decrease in early strength but the strength developed to the value as that of the conventional M25 concrete when 28 day tests were performed.
As the Mix M4 for 6% of waste plastic, the strength has been developed at 39.38 N/mm2 in compressive strength at 28 days.
It is observed that for more percentage addition of plastics i.e 6% in the present case, the 7 day strength has been increased when compared with conventional concrete. The Mix M4 for 6% of waste plastic, the strength has been developed at 4.38 N/mm2 in flexural strength of concrete. For Mix M4 for 6% of waste plastic, the strength has been developed to about 3.54 N/mm2 in split tensile strength in 28 days. For less percentage addition (2-4%) of plastic, there is no considerable variation in 7 day, and 28 day compression strength and split tensile strength.
Concrete with plastic waste can be used for less important works where concrete is not going to bear more loads.
