  • Roller-Compacted Concrete Slabs Using Phosphogypsum

    The use of phosphogypsum, a phosphate mining solid waste, was investigated as an aggregate in construction of various roller­ compacted concrete (RCC) slabs. Several phosphogypsum-based concrete mixtures were prepared in three different mixing pro­ cedures and were compacted using a self-propelled vibratory roller.
