Abstract

This study discusses the properties of Phosphogypsum-based roller compacted concrete. The described demonstration project indicates that phosphogypsum-based RCC is suitable for the construction of parking facilities. Phosphogypsum, without being detrimental to strength, contributes to good mix compactability and surface finish as a result of its fine grading. Two additional advantages are: (a) set retardation for a better bond at construction joints; and (b) drying shrinkage compensation to limit the occurrence of cracking when saw cut joints are not provided. The quality of aggregates plays an important role in strength properties of RCC and concrete in general and especially for roller compacted concrete pavements.
