Abstract

Through out the world, the most widely used construction material is concrete, commonly
made by mixing Portland cement with sand, crushed rock, and water. As concrete is being
widely used for the construction of most of the buildings, bridges etc, it has been labelled as
the backbone to the infrastructure development of a nation. Currently our country is doing
major to improve and develop its infrastructure by constructing industrial and commercial
projects and National Highways which creats major economic problem. At present about 120
million ton of cement is being produced in India every year. That much amount of cement
is expected to reach close to 470 million ton by 2017[3]. Though the production of cement
is at comfortable level to meet, the rapidly increasing cost of production of cement is a
matter of concern. Hence, currently the entire construction industry is in search of suitable
and effective the waste product that would considerably minimize the use of cement and
ultimately reduce the construction cost. Few of such products have already been identified
like Rice Husk Ash (RHA), Fly ash(FA), Silica fume etc. Amongst them RHA is known to have
good prospects in minimizing the usage of cement.
