THE EFFECT OF CEMENT ADDITIVES IN PVC MATERIALS
Journal Title: International journal of research -GRANTHAALAYAH - Year 2017, Vol 5, Issue 11
Abstract
The aim of the present paper is to show the effect of cement modifier behaviors in PVC materials. The PVC and the Portland cement are important materials in the industrial area. It can reach excellent properties if mixing the two materials with each other. The cement worked as filler in PVC, as shown the mechanical tests. The oxygen index was determined, accordingly the result show higher oxygen index value. That means the blend shows higher fire resistance comparing to neat PVC. The cement worked as a structural modifier, it caused modification in the blends structure and properties. From the mechanical tests, such as impact-, tensile-, flexuraland hardness tests the blend gives similar mechanical properties to neat PVC. The research presented in this paper shows that the cement mixed with PVC shows higher stability, fire resistance and similar mechanical properties as rigid PVC.
