Hydration Studies of Non-Portland Blended Cements made from Bag House Dust of Calcium Carbide Furnace

Abstract

Hydration studies were made of non-portland blended cements made from bag house dust and a number of industrial and agricultural waste materials exhibiting pozzolanic properties. The results have shown that the blended cements made from rice husk ash fired at 700°C have the best cementing properties. When bag house dust is mixed with granulated blast furnace slag, it is observed that there is an optimum amount of bag house dust which exhibits the best cementing properties. It has further been observed that in super-sulphated cements, bag house dust is a better activator of granulated blast furnace slag than lime. The overall hydration studies have shown that the blended cements reported in this communication can work as masonry cements in rural areas for non-structural work
