One of the main causes of the annual worldwide CO2 emissions caused by human activity is through the manufacturing of cement. Numerous initiatives and research are taking in place to reduce these CO2 emissions. The study was conducted on cement mortar samples and with 10%, 20%, and 30% of different type of fly ash (class C and F) replaced in part. The study examined the effect of immediate accelerated carbonation after casting (12 and 24 h), delayed accelerated carbonation (6 h of air curing followed by 6 and 18 h of CO2 curing after casting), and standard water curing on compressive strength of mortar samples. In addition, X-ray diffraction (XRD) was done for comparing carbonation curing and water curing results.

摘要

One of the main causes of the annual worldwide CO2 emissions caused by human activity is through the manufacturing of cement. Numerous initiatives and research are taking in place to reduce these CO2 emissions. The study was conducted on cement mortar samples and with 10%, 20%, and 30% of different type of fly ash (class C and F) replaced in part. The study examined the effect of immediate accelerated carbonation after casting (12 and 24 h), delayed accelerated carbonation (6 h of air curing followed by 6 and 18 h of CO2 curing after casting), and standard water curing on compressive strength of mortar samples. In addition, X-ray diffraction (XRD) was done for comparing carbonation curing and water curing results.
