Performance of Perforated Clay Bricks with Charcoal Waste as an Additive

In Rwanda, the traditional fired solid bricks embody high fuel consumption and quantity of clay during their molding. Traditional are also heavy compared to perforated bricks. This study aimed at investigating performance made soil (CS) mixed with charcoal waste (CW) as an additive. The physical, chemical mechanical properties CS 0, 10, 30, 40 50% CW were determined. extruded manually inclusion a varied number perforations: 4, 8, 12 15 perforations. analysis included determination organic carbon, exchangeable acidity components (through XRD) in matrix. depicted increase CaO proportions content. There was amounts cations. research found that perforations, weight loss is reduced. However, non-perforated least abrasion resistance, followed by 4 As content increased from 0 50%, perforations displayed highest resistance. concludes led linear shrinkage due calcium cations reduced magnesium soil. An optimum 30% identified for Bricks having below additive can be categorized category I (load-bearing)
