Partial Replacement of Cement by Brick Dust: A Review

Abstract

Due to the increase in construction activity, the demand of cementing material is increased. In 2010 based
on survey of world coal association, over 3.3 billion tons of cement was used. However, the increase in production of
the cement causes the environment problem due to emission CO2. In order to control the environmental impact, it is
necessary to partially replace the cement material by other cementing material. Several researchers are working on
the partial replacement of cement by other cementing materials in cement mortar. This review is presenting the
previous research on the partial replacement of cement by different cementing materials. On the other, huge amount
of broken bricks are wasted during construction activities. Several investigations are made regarding partial
replacement of cement and/or sand by these bricks in concrete and mortar. The objective of this study is to analyse the
effect of brick powder in cement in concrete and mortar. This paper presents a review and the comparison of the
results presented by the earlier researchers. It was observed that the replacement of cement by up to 10% of the brick
dust gives better result as compared to higher percentage. However, further study to justify the strength gain is
required as the brick duct was found to have lower percentage of CaO. But the percentage of SiO2 and Al2O3 was
found higher in brick dust as compared to cement.
