ABSTRACT

 

The project is a study of the use of recycled plastic in the form of granules to replace certain amount of aggregates in concrete. Concrete of various plastic proportions was tested to find the strength and workability curves. The aim is to optimise the substitution amount of plastic, based on strength and workability criteria of different proportions of substitution. Such concrete could be used for low strength applications; some of these being footpaths, slabs of foot over bridges, road fenders, support moulds and shallow foundations of electricity and light poles. Currently, for all the above applications conventional concrete is used, of which, only a part of its bearing capacity is utilised. The plastic substitute will save on the amount of aggregates used, while more importantly reducing plastic waste. There have been substitutions and additions in concrete mainly for increasing its strength, such as fibre reinforced concrete, but the proposed project focuses on utilising waste plastic which is an environmental concern.
