Heat Resistance of Concrete Incorporating Magnesium Oxide and Fly Ash in Portland Cement Binder System

Abstract

AbstractA cement binder containing around 30% reactive magnesium oxide (MgO) has the potential to reduce its carbon footprint because reactive MgO is produced at 600°C–700°C, whereas clinker requires a much higher temperature of 1,450°C. In this study, ...Practical ApplicationsIn this work, a reduction in CO2 emissions was achieved through the partial replacement of OPC with low-carbon reactive MgO and fly ash derived from coal industry waste. However, the resulting binder concrete was found to require ...
