State of the art review on Supplementary Cementitious Materials in India – I: An overview of legal perspective, governing organizations, and development patterns

Abstract

Growing concern over the environment has led the Indian Construction Industry towards Sustainable Development and Circular Economy. As a part of the solution, a part of clinker, the primary constituent of cement, is replaced by industrial by-product, waste ash, or similar fine materials, collectively known as Supplementary Cementitious Materials or SCM. Several organizations are actively engaged towards development, dissemination and promotion of technologies on SCM utilization. In Indian construction industry utilization of SCM is contingent on the existing legal framework, which includes relevant directives, standards, and technical guidelines. Literature shows directives have the highest influence followed by standards on the utilization of SCMs. Although provisions exist for utilization of SCMs in the absence of a relevant standard, they are rarely utilized. This makes knowledge of existing legal framework imperative for integrating studies on SCM utilization with industrial practices and subsequent development in the legal framework. The manuscript provides a state of the art review on existing legal policies, organizations influencing SCM utilization and an overview of development pattern. The manuscript will serve as a support tool for industry professionals, at the time of industrial application of SCM, and as an outline for the research community, for analysis of legal barriers. The manuscript will promote the utilization of SCM in the Indian construction industry through a better understanding of legal barriers. © 2020 Elsevier Ltd
