Materials such as ASTM C150 cement and Class F Fly Ash have been proven for decades to produce quality concrete. Recent changes to environmental policy and new sustainability goals within the concrete industry has led to changes in the types of materials available to produce concrete. With these changes comes uncertainty on the ability to produce quality concrete. This report summarizes available alternative cementitious materials and supplementary cementitious materials. It compares the fresh and hardened properties of concrete made with these materials. It also identifies the relevant ASTM documents that can be used to test and specify these materials.\", \"distribution\": [{\"@type\": \"dcat:Distribution\", \"accessURL\": \"https://data.usbr.gov/catalog/6395/item/72442\", \"description\": \"Landing page for \\\"S&T Project 19142 Final Report: Alternative Cementitious Materials for Increased Concrete Durability\\\"\", \"mediaType\": \"text/html\", \"title\": \"RISE Item Details Page URL for \\\"S&T Project 19142 Final Report: Alternative Cementitious Materials for Increased Concrete Durability\\\"\"}, {\"@type\": \"dcat:Distribution\", \"description\": \"\\\"S&T Project 19142 Final Report: Alternative Cementitious Materials for Increased Concrete Durability\\\" as a PDF file\", \"downloadURL\": \"https://data.usbr.gov/rise/content-rise-public/rise/catalog-item/binary/FINAL ST-2022-19142-01_Final 508.pdf\", \"mediaType\": \"application/pdf\", \"title\": \"PDF File for \\\"S&T Project 19142 Final Report: Alternative Cementitious Materials for Increased Concrete Durability\\\"\"}], \"identifier\": \"https://datainventory.usbr.gov/rise/item/72442\", \"keyword\": [\"Concrete Durability\", \"Fly Ash\", \"Portland Limestone Cement\", \"Sustainability\"], \"landingPage\": \"https://data.usbr.gov/catalog/6395/item/72442\", \"modified\": \"2022-10-03T11:19:09Z\", \"publisher\": {\"@type\": \"org:Organization\", \"name\": \"Bureau of Reclamation\"}, \"spatial\": \"{\\\"type\\\":\\\"Polygon\\\",\\\"coordinates\\\":[[[-105.12484,39.72238],[-105.1217,39.72366],[-105.1199,39.72123],[-105.12164,39.72052],[-105.12285,39.72213],[-105.12431,39.72153],[-105.12484,39.72238]]]}\", \"title\": \"S&T Project 19142 Final Report: Alternative Cementitious Materials for Increased Concrete Durability\"}","source_transform":null,"status":"error"}
