Abstract
Strength properties of the concrete and shrinkage reducing effect using non-iron slag fine aggregate were investigated. As a result, it was found that concrete with non-iron slag was higher strength characteristics and shrinkage suppression effect than those with the natural aggregate. In addition, it was suggested that the specific surface area of the aggregate and reaction layer volume formed between the aggregate and the matrix paste would be factor of the shrinkage suppression effect. Authors proposed equations to evaluate the effects of non-iron slag fine aggregate on the compressive strength and shrinkage strain.
