The role of cementitious materials in the next decade

Abstract

This paper presents a personal perspective on the potential impact of cementitious materials in the construction industry over the next decade. While it is true that today concrete and its derivatives are ubiquitous, their presence and use can only grow as academia and industry address the challenges of sustainability and resilience. The paper briefly discusses some of the topics that will fuel this growth and can be considered low-hanging fruits. They include: A) new classes of binders complementing portland cement; b) additives that transform fresh properties; c) non-corrosive reinforcement resulting in concrete without chloride limits; d) use of saltwater and recycled/alternative aggregates; and, e) brittle matrix composites for repair. Many other cutting-edge technologies such as nano-materials, ultra-high performance concrete, self-healing concrete, engineered cementitious composites and 3-D printing are not discussed as their impact will be most likely felt in the following decades. Advances and deployment of technology will make the concrete industry greener and more conscious of its environmental impact while, at the same time, providing means and methods to extend the useful life of existing concrete structures.
