Trinity Lightweight offers the ability to provide a variety of grading options to suit your particular needs. Use this versatility to specify the optimum material for any given application. As with ordinary aggregates, the engineering properties of expanded shale and clay lightweight aggregate vary depending on aggregate source and grading.
Be sure to consult Trinity Lightweight during the conceptual design phase, for precise information on the aggregate properties needed for your project. Whether you need a specific grading, bulk density (unit weight), in-place compacted density, angle of internal friction, thermal conductivity, or other property for a geotechnical fill project, or low density, high strength concrete for your building or parking structure, Trinity Lightweight can help.
