A Discussion Of The Paper “Use Of Zeolite, Coal Bottom Ash And Fly Ash As Replacement Materials In Cement Production” By F. Canpolat, K. Yýlmaz, M.M. Köse, M. Sümer, M.A. Yurdusev

This brief article comments on a research study (Canpolat et al, 2004) that used three different combinations of tests to investigate the effects of zeolite, coal bottom ash, and fly ash as Portland cement (PC) replacement materials. The study investigated properties including setting time, volume expansion, compressive strength, and water consistency of the mortar. Results showed that replacement materials have some effects on the mechanical properties of the cement. In this commentary, Un contends that some of the study authors' interpretations about zeolites are misleading. Indeed, Un maintains that the cements produced in this study are not appropriate for comparing the effect of zeolite on the initial strength of specimens. To investigate the clear effect of zeolite replacement, cements with similar fineness have to be produced.
