Title: Autoclaved Alumina-silica Rich Industrial Waste Cement Systems Incorporating Reactive Magnesia
Appears on pages(s):
Abstract:The utilisation of industrial waste products as supplementary cementitious materials to produce blended Portland cement has increased worldwide in recent years. This study aims to investigate physical and mechanical properties of the addition of claybrick waste and reactive magnesia (MgO) as a low-emission alternative to ordinary Portland cement (OPC) binders in autoclaved calcium silicate based building products. The addition of clay-brick waste was found to be beneficial for drying
shrinkage reduction but had an adverse effect on strength development. The addition of reactive MgO also showed a decrease in compressive strength but had some positive effects on bulk density. For the combined addition of clay-brick waste and magnesia an apparent synergy was observed which has been explained by the complementary physical and chemical effects.
