dc.description.abstract The utilisation of industrial waste products such as fly ash, blast furnace slag and fired claybrick, as supplementary cementing materials to produce blended Portland cement (PC) has increased worldwide in recent years. The incentive was directed towards the utilisation of wastes and industrial by-products in order to minimise PC consumption, thus reduce CO 2 emissions. This study aims to investigate the potential of magnesia (MgO) as a supplementary material in combination with alumina-silica rich fired clay brick waste fines. Compressive strength results showed adverse effects on the additions of brick waste fines and MgO. However, for blended PC with the addition of both brick waste and magnesia, an apparent synergy, indicating a minimising of strength reduction, was observed. X-ray diffraction (XRD) data revealed the presence of brucite, a hydration product of MgO, in the MgO blended PC suggesting a lack of pozzolanic activity of MgO.
