INVESTIGATION AND COMPARISON OF MATERIAL PROPERTIES AND NORMAL CONCRETE WITH WASTE PLASTIC AGGREGATE AND REPLACED COARSE AGGREGATE CONCRETE

Abstract

For developing countries like Pakistan, waste disposal and management is one of the important issues which
need to be addressed urgently. Today, in Pakistan a large quantity of waste accumulated in cities and towns. This is a big
challenge for the government to safely dispose-off these waste so that to provide a good and healthy environment.
Plastics are stable material and are not biodegradable material. Their open disposal creates problems in surrounding
environment. In this scenario research studies are going on all over the world for the effective use of plastic waste as an
addition and partial replacement of coarse aggregates in plain concrete and reinforced concrete as well for many
reasons [1, 2]. This research study will help in contributing the effective utilization of plastic waste in RC concrete
structural members in order to minimise the environmental pollution. Three types of concrete are made with 0%, 5% &
10% replacement of coarse aggregate with palletized coarse aggregate. The properties of materials were individually
found out in laboratory & compared with plastic aggregates. The mix proportion is prepared on the basis of the
properties of materials for concrete of 3000 psi compressive strength. The resulting reference concrete with all natural
aggregates is then compared coarse aggregate replaced concretes for compressive strength & tensile strength. It was
found that the compressive strength & tensile strength are reduced but the concrete can be used at places of low strength.
This research also gave the basic data for effective utilization of plastic aggregate in concrete with basic guidelines.
