Abstract
The goal of this study was to test the viability of using red clay brick waste (RCBW), concrete waste (CW) and glass waste (GW) to produce alkali-activated cements (AACs) that can be used to fabricate blocks, pavers, roof tiles and tiles. The alkaline activators used were solutions of either NaOH or NaOH and waterglass. Ordinary Portland cement (OPC) was mixed with RCBW and CW in proportions of up to 30% to create hybrid cements. The AACs obtained with the RCBW, the CW and the GW exhibited maximum compressive strengths (28days) of 102, 33 and 57MPa, respectively.
