SUPERPLASTICIZED FLOWING CONCRETE STRENGTH AND DEFORMATION PROPERTIES

This paper investigates superplasticized high-workability concrete. The properties described are those of strictly flowing concrete in the hardened state and include: compressive strength, drying shrinkage, thermal expansion, elastic deformation, creep, creep recovery and post-creep- recovery elastic deformation and strength. It is shown that flowing concretes made with superplasticizers of categories a and b exhibit similar properties. In comparison with the corresponding normal concrete, flowing concrete, for a given strength, is likely to require a slightly higher cement content, it exhibits higher shrinkage, slightly higher elastic modulus and lower creep, whilst its creep recovery and post-creep-recovery elastic deformation and strength properties are generally comparable. With regard to the various mix, curing and testing parameters considered, both normal and flowing concretes appear to respond in a similar manner for the properties studied. (Author/TRRL)
