Experimental Study on Compressive Strength of the Cement Mortar Cubes with Partial Replacement of Fine Aggregate Using Polyvinyl Chloride (PVC) Plastic

Mortar is a material that consists of cement and sand with a range of applications in the construction industry. However, the plain mortar materials are usually brittle and often crack and fail more suddenly than reinforced mortar. This experimental study is about the compressive strength of cement mortar stabilised with the use of the polyvinyl chloride (PVC) plastic powder. Generally the compressive strength of cement mortar of mix proportion (1:3) is 33 N/mm² to 53 N/mm² has been obtained after 28 days curing. The cement mortar ratio is 1: 3 respectively. The PVC powder is added along with the sand with percentages of 0%, 2.5%, 5%, 7.5%, 10% respectively. And the water cement ratio is 0.5 with volume. The moulds of 70×70×70 mm size were used for the cube test, and the cubes were tested on the Compressive testing machine to determine the strength of cube for 3, 7, 28 days of time period respectively. The main aim of f this study to determine the compressive strength of cement mortar (1:3) of sand added with PVC powder,
