Supplementary Cementitious Materials for Green Concrete
Journal Title: JOURNAL OF ADVANCED RESEARCH IN CONSTRUCTION AND URBAN ARCHITECTURE - Year 2017, Vol 2, Issue 1
Abstract
Concrete is the second most used material on the earth, after water. It is considered to be one of environmental-friendly materials of construction. Yet producing the Portland cement which binds concrete together is energy intensive and emits enormous amounts of carbon dioxide (CO2) which is known to be a greenhouse gas (GHG) that contributes to global warming. During the past few decades, the potential of Portland cement in terms of its effective utility has been realized. As a result, the use of new admixtures has increased significantly within the concrete industry. Properties of concrete can be modified by the use of mineral admixture with partial replacement of cement, to increases long term strength and durability. Green Concrete is capable for sustainable development which characterized by application of industrial waste such as coal fly ash, slag, rice husk ash, etc, to reduce consumption of cement, natural resource, energy and pollution of the environment. In this paper, brief overview is presented related to availability and necessity to use various industrial by-products as supplementary cementitious materials in concrete towards sustainable development.
