Self-compacting concrete ( SCC ) is able to flow without segregation and without the addition of energy. It was developed in Japan in 1988, and European development began in Sweden in the 1990s. SCC requires accurately graded aggregate and high powder contents to enhance cohesiveness. This is usually achieved by the addition of ground blast furnace slag, pulverised fuel ash or inert materials such as limestone. Relatively little skill is required for pouring, and the properties are generally similar or superior to those of the equivalent conventional concrete. Organisations researching, producing and using SCC in Europe are given. 60 refs.
