Due to scarcity of natural stone, a large number of residential building in Bangladesh are constructed using crushed clay brick aggregate. Since production of brick aggregate consume large amount of energy and hence emit higher quantity of CO2, environmental impact from brick aggregate would justifiably be different from concrete made from natural stone aggregate. It is, therefore, of interest to know how choosing either of the two types of aggregate affects the overall CO2 emission in a building construction project. To this end, in this paper, a comparative study is conducted between CO2 emission of identical brick and stone aggregate concrete six storied residential building located in Dhaka, Bangladesh. For this, the construction materials, their quantities and respective CO2 emission are estimated and tallied. All the processes involved from production, transportation to the site, installation etc are considered while estimating CO2 emission from each construction material. Total CO2 emission from the two different types of concrete building is later compared. Comparison shows that brick aggregate concrete building emit approximately 28% higher CO2 than natural stone aggregate concrete building.
