Abstract: The lack of technical information on the use of local building materials has driven the consumers to use industrializad construction materials. There is a lot of research on manufacturing concrete reinforced with agro-residues such as: coconut shell; sisal; sugar cane bagasse; bamboo; jute; wood; hemp; and bananama). But the fibre most used to reinforce cement has been the bamboo species. The giant reed (Arundo donax L.) is a plant with a hollow stem that resembles a bamboo. The purpose of this study was to use giant reeds to reinforce cement mortars in order to provide some technical data on the traditional building uses of this plant, and to manufacture a new product based on the ancient mediterranean building techniques.

Abstract: 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
