Investigation of the use of non-biodegradable waste materials in concrete via experimental research

Abstract

Plastic trash disposal is a big problem in current time, since the usage of plastics is rising all the time, and plastic material took 100 years to degrade. There are several practical solutions for recycling and repurposing plastics being developed. This research investigates the use of non-biodegradable plastic aggregate generated from high density polyethylene (HDPE) waste in place of natural fine aggregate in concrete. To determine the best replacement, substitute fine aggregate weight by 10 %, 20 %, 25 %, or 30 %. Compressive strength, split tensile strength, and flexural strength tests are performed on hardened concrete as well as basic tests on fresh concrete, such as the slump cone test and compaction factor test, to determine the characteristics and behavior of concrete utilizing plastic aggregate. The results of concrete generated strength in the hardened condition of concrete and basic tests on fresh concrete, such as the slump cone test and compaction factor test, were taken care of after the casted specimens were tested for various days, such as the 7th, 21st, and 28th days. After testing for 7, 14, and 28 days, the outcomes of concrete made with plastic aggregate are contrasted with those of conventional concrete.
