Effects of Fly Ash, Calcium Carbonate Fillers on Mechanical, Moisture Absorption Properties in Poly Vinyl Chloride Resin

In recent years the demand and applications of synthetic resin (PVC) has got increased manifold. This study is aimed at the enhancing the properties of PVC by adding tillers like fly ash and calcium carbonate with it. There after the synthesized composite has been tested for moisture absorption property, compression property, hardness and hygrothermal ageing. The moisture content test is conducted as per ASTM D570 standard, where the specimen under study has been heat treated and cooled in desiccators. Then the weight of the specimen is measured and thereby calculating the moisture absorption characteristic of the material. The test setup for compression a follows the ASTM D790 standards in which the load with standing property is conferred by means of UTM (Universal Testing Machine). Hardenability of specimen is evaluated (as per ASTM D2240 standards) by shore D hardness test in durometer scales. The hygrothermal test procedure is similar to that of moisture content test where the ability of the specimen to transfer heat is measured. The results from the test indicate that the PVC resin with 33.05 percent fly ash is the most suitable for practical applications. (C) 2019 Published by Elsevier Ltd.
