Self-compacting concrete mixtures can be used in different structures with heavy reinforcement such as bridges, walls and foundations, without bleeding and segregation. The utilization of new materials such as natural and by-product materials that could probably decrease the CO2 emission of cement factories, is the main goal of this study. In this study in order evaluate the results of fresh and hardened properties of self-compacting concrete, Portland cement was replaced by (5%, 10% and 15%) natural zeolite and (20%, 30% and 40%) slag in the binary mixtures. The mixtures incorporating ternary cementitious blends (ZS20, ZS30 and ZS40) were made with 10% zeolite and (20%, 30% and 40%) slag. These materials are acting both as the cementitious admixtures as well as the fine filler in self-compacting concrete. Properties such as slump flow, J-ring, V-funnel and T50 were investigated for evaluating the fresh properties of self-compacting concrete mixtures. Also mechanical test such as compressive strength of hardened concretes was carried out. Replacement of supplementary cementitious materials improved the compressive strength of mixtures especially at later ages. At 180 days, the highest compressive strength of mixtures containing zeolite, slag and ternary mixtures belonged to Z10, S30 and ZS30 with 58.5, 58 and 58.7 MPa respectively. https://ajce.aut.ac.ir/article_3329_ac8cd1808dc30460a81cab1b0e6652fa.pdf
