Reducing CO2 Emission through Green Building Design by Partial Replacement of Cement and Aggregate by Silica Fume, Egg Shell and E-Waste: A Review

This research review represents the collection of data from various previous studies done on the compressive strength, flexural strength, tensile strength testing of concrete incorporating Silica fume & Egg shell by optimum replacement of cement and E-waste by replacement of aggregate. Portland cement is now a days partially replaced by silica fume, a by-product from silicon alloy factories and Egg shell, a waste produced in poultries. From various studies Silica fume is a non-metallic and non-hazardous material having very large surface area and egg shell have high percentage of lime which will provide binding property whereas E-waste is also used which will provide workability to concrete, which is suitable for concrete mix. This review paper is a good source for understanding the effect on optimum replacement of cement by silica fume and aggregate by E-waste.
