The role of microsilica in sustainable concrete

Abstract

This paper reviews at the way we approach sustainability with concrete construction. It looks at the current thoughts on how to achieve this and asks if we are trying to be too green and actually potentially causing problems for the future. It reviews projects around the world that are using multiple cementitious blends to achieve long term durability and reduced construction costs. The point is raised that despite a drive to be green and be sustainable, the criteria for many projects is still the cost per cubic metre.
