It is often said that there are two types of concrete: concrete that has cracked and concrete that is going to crack. Unfortunately, this is true all too frequently. Many of these unwanted cracks develop shortly after the concrete is placed and in addition to being unsightly these cracks can contribute to reduced long-term durability. This cracking may be attributed to the fact that unlike many other materials that are prepared in factories under relatively well controlled conditions, a large proportion of concrete is cast on site under a wide range of climatic conditions (wind, temperature, relative humidity). This article discusses some promising research that is reengineering conventional concrete mixtures to make them more robust (i.e., defined by Websters Dictionary as capable of performing without failure under a wide range of site conditions) for field construction.
