Abstract

Foamed concrete bricks (FCB) have high levels of porosity to sequestrate atmospheric CO 2 in the form of calcium carbonate CaCO 3 via acceleration of carbonation depth. The effect of density and curing conditions on CO 2 sequestration in FCB was investigated in this research to optimize carbonation depth. Statistical analysis using 2 k factorial and response surface methodology (RSM) comprising 11 runs and eight additional runs was used to optimize the carbonation depth of FCB for 28 days (d). The main factors selected for the carbonation studies include density, temperature and CO 2 concentration. The curing of the FCB was performed in the chamber. The results indicated that all factors significantly affected the carbonation depth of FCB. The optimum carbonation depth was 9.7 mm, which was determined at conditions; 1300 kg/m 3 , 40 °C, and 20% of CO 2 concentration after 28 d. Analysis of variance (ANOVA) and residual plots demonstrated the accuracy of the regression equation with a predicted R 2 of 89.43%, which confirms the reliability of the predicted model.
