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/m3 and a water-to-binder (w/b) ratio
of 0.35. Also fly ash content
of the concrete batch was 110 kg/m3 . 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
(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.
