UTILIZATION OF UNPLASTICIZED POLYVINYL CHLORIDE (UPVC) WASTE IN MASONRY MORTAR

Abstract

This article presents the using of wasted unplasticized polyvinyl chloride (UPVC) plastic from cutting process of doors and windows made from UPVC in masonry work mortar to reduce the plastic disposal to environmental. Wasted fine crushed UPVC was replaced to sand in percentage of 0, 5, 10, 15 and 20 %wt. Flow of mortar was controlled at 115±5% by using water adjustment. The result showing the mortar in addition of used percentage UPVC having the reduction of density from 2150 kg/m³ to 1820 kg/m³, increasing of water absorption due to higher porosity, and decreasing of compressive strength from 468 to 410, 341, 254 and 180 kg/cm². The compressive strength of UPVC-mortar presented higher value from Thai industrial standard. Moreover, the using of 5-10% of UPVC in mortar can reduce the drying shrinkage. It can be note that the masonry mortar can compose wasted fine crushed UPVC in quantity of 10%wt with maintain acceptable mechanical property related to Thai industrial standard. And using of UPVC in construction material is reduce the wasted disposal to environmental and promote value of industrial waste and mortar work to green construction material.
