Özet
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 28 days. When samples with limestone and calcite powder were immersed in chemical solutions, compressive strength of samples decreased and weight loss increased. (C) 2014 Elsevier Ltd. All rights reserved.
