Abstract
Cement is the most important material for construction industry. Key raw material for cement Manufacturing is limestone and it’s a non-renewal source of material. The high demand and limited reserve of limestone create a challenge to use this non-renewal source in optimum way and to reduce the wastage. To counter this challenge, RMC has been developed. However in India, its usages are limited due to lack of studies of its effectiveness in sub-continental conditions. In this work a study is made to identify the quantum of wastages and effectiveness of RMC to reduce this wastage. Suggestive measures are also discussed to overcome the constraints in the use of RMC in India. This study shows that RMC may be proved a game changer in conservation of cement strength if more emphasis can be given on development of RMC industry and to educate the stack-holders about its benefits and way of use. It is concluded that masons have measured role in house construction so lot of education certified courses are needed to implement to educate them for usage of cement and concrete batching. Government, Cement companies and RMC industries need to focus on this account to prevent wastage of extra cement by volume batching (Nominal Mix) and need to promote concrete mix design by weight.
