MgO-Based Cementitious Composites for Sustainable and Energy Efficient Building Design

Concrete made with Portland cement is by far the most heavily used construction material in world today. Its success stems from fact that it relatively inexpensive yet highly versatile and functional widely available raw materials. However, many environments, concrete structures gradually deteriorate over time. Premature deterioration of a major problem worldwide. Moreover, production energy-intensive releases lot CO2; this compounded its ever-increasing demand, particularly developing countries. As such, there an urgent need to develop more durable concretes reduce their environmental impact improve sustainability. To avoid such problems, researchers are always searching for lightweight structural materials show high performance during both processing application. Among various candidates, Magnesia (MgO) seems be promising attain target. This paper presents comprehensive review characteristics developments MgO-based composites applications cementitious energy-efficient buildings. starts characterization MgO terms processes, calcination temperatures, reactivity, micro-physical properties. Relationships between different building designs were established. Then, influence incorporation on properties indoor quality was summarized. Finally, future research directions discussed.
