Abstract

The aim of this paper is to present compressive strength characteristics under air-dry, sealed and soaked conditions of portland cement mixtures containing a complete range of combinations of dihydrate phosphogypsum (by-product of the phosphate fertilizer industry) and fine aggregate (crushed lime rock). Cylindrical specimens were prepared according to the Modified Proctor procedure (impact compaction). Based on these results, strength comparisons are made for selected constituent proportions in the cases of: 1) consolidation by static compaction; 2) consolidation by high-frequency vibration; 3) site consolidation by vibratory roller compactor; 4) substitution of the dihydrate phosphogypsum with the hemihydrate form (other available by-product). It is shown that consolidation by compaction is particularly advantageous because of the contribution of phosphogypsum to strength development. Laboratory compacted samples of the by-product alone indicate that strengths of over 1,000 psi (6. 89 MPa) can be achieved.
