Abstract :The aim of this study is to investigate the effects of using polyvinyl chloride dust on the compressive strength and shrinkage behavior of self-compacting concrete. Self-compacting concrete mixtures with polyvinyl chloride dust content were designed with a total binder content of 550 kg/m 3 and a water-to-binder insert ignore into journalissuearticles values(w/b); ratio of 0.35. Also fly ash content of the concrete batch was 110 kg/m 3 . Polyvinyl chloride dust was   added in place of Portland cement at replacement levels of 0%, 5%, 10%, 15%, 20%, and 25% by weight in all mixtures. Six mixtures insert ignore into journalissuearticles values(one is selected as control mixture); were used in the study. According to test results, the compressive strength of the concrete samples   significantly decrease with increasing polyvinyl chloride dust content. Dry shrinkage decreses when the percentage of polyvinyl chloride dust in the self-compacting concrete mixture increases. Similar to the drying shrinkage test results, self-compacting concrete incorporated with    polyvinyl chloride dust exhibite lower weight loss in comparison with the control mixture. Also restrained shrinkage rate   of   self-compacting concrete specimen decreases when the percentages of polyvinyl chloride dust   in specimen increse.
