A REVIEW ON STRENGTH ASSESSMENT OF GREEN CONCRETE USING DIFFERENT ADMIXTURES

Abstract

Generation and handling of construction and demolition (C&D) waste has been focused to achieve
sustainability goal at the developing stage of any country. If measures to minimize and handle the C&D waste are not
developed and efficiently adopted, it may threat the environment as well as sustainable movement of Indian
construction industry. C&D waste in India in 2010 may be estimated as 24 million tonnes. Owing to growth in
construction in India, it is appropriate to link generation of C&D waste with the growth. Also the demolition of older
structure may have concrete waste, which is deposited anywhere and put the adverse effects on the environment. By
adopting waste concrete debris as recycled concrete aggregate (RCA), the conservation of natural resources and cost
effectiveness in construction may be achieved. In the present study, an attempt has been made to study the various
research papers related to RCA as a partial replacement of normal coarse aggregate (NCA). Also, the papers
introducing the mineral admixtures such as, cow dung ash, fly ash, marble dust, etc. as a partial replacement of
cement have been studied. And the fruitful concluding remarks have been made. Also, the paper provides an overview
of the construction industry in India.
