GOING WITH THE FLOW

The paper reviews a technology, first developed in Japan in the 1980s, that uses advances in admixtures and mix proportions to create self-consolidating concrete (SCC). The key to creating SCC is production of mortar with a low yield value with a high enough viscosity to support the coarse aggregate. Polycarboxylate ether based superplasticizers have been found to produce the desired flowability through production of the best water reduction and slower slump loss. Also discussed is the need to establish standard test methods to measure the relevant properties of fresh SCC and to set performance requirements for the material.
