•We investigated the engineering properties of the new binding materials.•The volume expansion of samples were increased with amount of stone powders.•The strength of samples were decreased with increasing amount of stone powders.•With addition of FA were increased the strength of samples after 28days.•Mass loss and damage have not been observed in any of the samples with FA addition. In this study, a new binding material obtained by mixing limestone, calcite powders and fly ash in various ratios were used instead of mineral admixture in CEM II/B-M. Mechanical and physical properties of the samples were tested. Results showed that an increase which agreed with the standard requirements was observed in the setting times and volume expansion of paste samples with increasing amount of limestone and calcite powder. Also, the compressive strength of mortar samples decreased with increasing the amount of limestone and calcite powder. Compressive strength of samples with fly ash had a significant increase after 28days. When samples with limestone and calcite powder were immersed in chemical solutions, compressive strength of samples decreased and weight loss increased.
