MECHINICAL PROPERTIES OF SUSTAINABLE CONCRETE WITH WASTE PLASTIC BAGS

Abstract

Disposal of waste material like plastic bags is a large problem in a developing country such as
Iraq. Waste plastic bags (WPB) is a gentle of non-degradable material which leads to environmental
pollution. The present study covers the use of WPB as a volumetric alternative for fine aggregates for the
purpose of producing sustainable concrete. Three various percentages 10%, 20% and 30% of WPB had been
utilized like a volumetric alternative for fine aggregates within concrete. The features for concrete mixes that
include water absorbing, dry density, ultrasonic pulse speed, compressive strength as well as flexural strength
had been studied. The outcomes show that the inclusion of WPB makes a decrease within compressive
strength, flexural strength, dry density and ultrasonic pulse speed by 7 plus 28 days. Furthermore, the
outcomes refer to an increase within water absorbing at 7 days plus 28 day. The reducing ratio of
compressive strength to concrete comprising 10%, 20% plus 30% of WPB is 42.2%, 56.6% and 83.03%
respectively at 7 days, and 48.9%, 61.2% and 80.8% respectively at 28 days. The reducing ratio of flexural
strength to concrete comprising 10%, 20% plus 30% of WPB is 14.9%, 38.8% and 56.4% respectively at 7
days, and 31.9%, 52.2% and 61.4% respectively at 28 days. The use of WPB gives different benefits, among
such benefits is the use of WPB which produces a lightweight concrete and that depends upon WPB’s ratio
being utilized.
