A Comprehensive Exploration on Sustainable Supplementary Cementitious Materials Derived from Agro-Wastes

Concrete is one of the most popular construction materials in the present world. Cement is the binding material used in concrete and its production requires large quantity of natural raw materials and generates enormous volume of greenhouse gases like CO2 . In developing and under developed countries, the primary sector forms the crucial part of the economy. The management of waste generated from agricultural sector is becoming a major concern due to their negative impact on the environment. Under this scenario, several researchers have developed supplementary cementitious materials (SCMs) from these by products that can be used as a cement replacing material in concrete. Many of these materials have shown great performance and they enhanced the fresh and hardened properties of concrete. This paper is aimed at reviewing the performance of various SCMs from agricultural waste materials. Reviewing such materials helps to identify and develop new materials
