Engineering Properties of Concrete made with Brick Dust Waste

This research work reports the potential of using Brick Dust Waste (BDW) as a partial substitute for Portland Cement (PC) in the development of concrete. BDW is a recycled waste materials that is sourced from the demolishing of fired clay brick buildings or the discarded by-product materials from the cutting of fired clay bricks into shape and sizes for the construction of chimneys, and other uses needing the use of fired bricks. This results in the disposal of BDW as an environmental problem of concern. BDW has pozzolanic properties that enables it play an important role in the strength and durability of concrete, its use in concrete will alleviate the increasing challenges of scarcity and high cost of cement and will help to strike a balance between the sustainability of the environment and the demand on construction due to the increase in population growth worldwide. In order to investigate the Cement replacement potential of BDW, four types of mixes were designed at varying BDW replacement levels—10%, 20%, 30% and 40% with a water binding ratio of 0.6 and tested at 7, 14, and 28 days. The testing programme included material characterisation, the determination of slump value and compressive strength
