| dc.description | Abstract: This study consisted of a preliminary geological and engineering evaluation of natural brick and cement materials on St. Croix, U. S. Virgin Islands. The analyses of geological literature, maps, and aerial photographs revealed that the Kingshill Marl (Miocene) should be investigated as a source for cement and that the Jealousy formation (Oligocene) and Quaternary alluvium be investigated as possible source material for bricks. Geological field work and sampling were conducted at selected sites·where these geologic units were exposed. The classification tests conducted on the collected samples included mechanical analyses, Atterberg limits, chemical, and mineralogical. The tests used to determine suitability as brick material included extrudability, shrinkage, and green and dry strengths. The constraints to commercial manufacture of brick and cement were studied in terms of material properties, volume and variability, and land use. The Kingshill Marl was found to be highly calcareous material totally lacking deleterious constituents and possessing a composition suitable for the manufacture of cement. The Quaternary alluvium and the Jealousy formation are plastic clays containing predominantly smectite and calcite. These clays, particularly the Quaternary alluvium, were found to be highly suitable for brick manufacture in terms of extrudability and fired strength. Shrinkage and lime hydration are manageable constraints to the use of these clays in brickmaking. The volume of potential cement and brick materials is believed to be sufficient for commercial operations. The vertical and horizontal variability is not known and must be determined. The studied brick and cement materials occur in areas that have been zoned for agriculture or are on public land. Zoning is not considered a serious restraint. | - |
