Detailed Webinar Instructions
Concrete mixtures can include lightweight coarse and/or lightweight fine aggregates. This presentation will explain the process of mining shale and expanding it into lightweight aggregate. Applications of products from expanded shale include bridge decks, slabs-on-deck in buildings, and internal curing. There is a section of the presentation that includes excerpts from the NYSDOT 2017 Bridge Manual that requires internal curing in the concrete for bridge decks, sidewalks, crash walls, and approach slabs. Also included are a few project profiles for bridge decks, concrete paving, and pervious concrete.
