Abstract

Owing to the growing road network needed for increasing developmental activities, massive burden is being posed to the environment in terms of direct products and by-products. Cement is the prime construction material for rigid pavement, and its huge production to meet out the demand is of great concern for environmentalists. During the production of cement, various harmful gases are emitted, out of which CO2 is of prime concern. Several materials, viz., fly ash, rice husk ash, GGBS, silica fume and metakaolin can be used as partial replacement of cement in construction. The use of supplementary cementitious materials in construction not only improves the mechanical property of the cement matrix but also reduce the burden of the environment. In this paper, an attempt has been made to explore the possibility of using rice husk ash as a partial replacement of cement in the rigid pavement to lower down the carbon footprint.
