In this study, poly-silicon sludge was used in replacement with Portland cement as SCMs. Poly-silicon sludge has an ability to improve the durability to the concrete system. Thus, the chloride penetration test of PS specimens was conducted for the confirmation of the durability. From the results, The penetration depth of the plain specimens is deepest, and gradually decreases as PS substitution rate increases.
