Assessment of Mechanical Properties of Concrete Using Waste Plastic Gel as Replacement of Water-Cement
Subject area: Science,Engineering and Technology · Area of research: Material Testing

Abstract
Concrete is a fundamental engineering material used in modern construction. The use of plastic waste in concrete as a binding material can reduce the use of cement and help to reduce plastic waste in the environment. This study aims to replace water cement with waste plastic gel. Plastic gels were prepared by heating mixed waste plastic in a container at high temperatures with sand and aggregate. 150 mm x 150 mm concrete Testing cubes are prepared. This study investigates the optimum quantity of waste plastic gel with different mix ratios (1:3:6, 1:2.5:5, 1:2:4, 1:1.75:3.5, and 1:1.5:3) and found that mix ratio (1:1.75:3.5) gives maximum compressive strength. Samples were tested in 3 days, 7 days, 14 days and 28 days and compressive strength was almost constat. Water absorption is also minimum in waste plastic concrete.
