Suitability Assessment of Fly-Ash GGBS Based Rammed Earth Material A-Sustainable Construction Building Material – A-Review

Abstract

Rammed earth is an construction technique which is very ancient , as this technique has capacity to produce environmentally sustainable construction materials  due to which this has been gaining attention  of the researchers . A rammed earth construction  technique is a monolithic construction made by compacting processed soil in progressive layers in a rigid formwork. The requirement of soil type in construction of rammed earth is lateritic soil. However, this type of soil is not available in many regions of India. Therefore, an attempt has been made to study the suitability of locally available non swelling soil blend with industrial wastes in form of GGBS (Ground granulated blast furnace slag) and fly ash for rammed earth construction. Fly ash is a by-product from burning pulverized coal in electric power generating plants. GGBS is obtained from blast furnace slag, a by-product from the manufacture of iron. Waste materials utilization is not only the promising solutions for disposal problem, but also saves construction cost. This paper gives details about the various studies carried out on stabilized rammed earth materials  by utilizing different industrial wastes  cementetious materials like, lime, ground granulated blast furnace slag, and rice husk ash. The paper also explains the state of the art of utilizing stabilized rammed earth blocks.
