  • Abstract:
  • This investigation focuses on emission of co2 coupled with non-absorption of the same on account of deforestation etc. has caused tremendous environmental pollution leading to global warming and other bad effects. It is estimated that about 7% of greenhouse gas is being emitted into the atmosphere annually on account of production of OPC alone. So it is a need of the time to find some substitute of cement. In order to reduce the environmental pollution .In this experimental investigation, we were replaced the cement by using magnesia for manufacturing of concrete along with coarse aggregate and fine aggregate. Magnesium deposits exist in abundance in every corner of the earth and cover roughly 8% of the world’s surface. Depending upon where they are mined, magnesium oxide and magnesium oxide/magnesium chloride cements require only 20%-40% of the energy required to produce Portland cement. Magnesium oxide is extracted from magnesium ore like as magnesium carbonate, dolomite, and magnesium sulphate. As compared to burning of limestone it will produce less amount CO2.So replacing the calcium oxide by magnesium- oxide. The magnesium have lower atomic radius than the calcium. Hence it has higher strength and denser. We were prepared cement by mixing of magnesia and un-calcined clay. In the sources of materials, to hydrate to form M-S-H gel. The M-S-H gel binds the loose coarse and fine aggregates to form concrete. M-S-H gel replaces the C-S-H gel in OPC cement. For this purpose along with a Control Mix, 45 cubes are prepared to study the compressive strength. Test on magnesia based cement and coarse aggregate, fine aggregate are conducted as per Indian standards. Results shows the strength of magnesia based cement concrete.
