Arcosa Lightweight is a leading supporter of research, independent testing and field studies and we maintain an extensive library of case studies that detail the beneficial uses of our product.
The superior qualities of expanded shale, clay and slate lightweight aggregate are effective and economical in many applications. ARCOSA, Inc. is a diversified industrial company that owns market-leading businesses providing products and services to the energy, transportation, chemical, and construction sectors.
Structural lightweight concrete made with rotary kiln produced structural lightweight aggregate solves weight and durability problems in buildings and exposed structures. Structural lightweight concrete achieves strengths comparable to normal weight concrete, while being 20% to 30% lower in density.
Walls constructed with lightweight concrete masonry units — or concrete block — are a time-tested, proven construction system, delivering benefits that range from structural, to thermal, to aesthetic.
Many coastal areas have lost thousands of acres of shoreline to erosion. Previous hurricanes have led to vast areas of land just disappearing. Storms, along with the loss of marsh grasses and other vegetation, have taken a toll. To maintain what’s left and bring back what was lost, Arcosa Lightweight aggregate is being used to help in coastal protection and restoration efforts.
Internal curing offers benefits of improved hydration, reduced chloride ingress, and reduced early age cracking, which helps concrete achieve its maximum potential as a sustainable building material by extending its service life.
For innovative, cost-effective, long-term solutions for horticulture projects, professionals often turn to lightweight aggregates. From creating an ideal planting media to designing a soil for an athletic field, Arcosa Lightweight is the logical solution.
Arcosa Lightweight's expanded shale and clay lightweight aggregate can reduce the density of compacted geotechnical fills by up to one-half. This advantage, coupled with its predictable high internal friction angle, can also reduce lateral forces by more than one-half.
Combining lightweight aggregates with varying amounts of organic matter creates a lightweight planting media for intensive and/or extensive rooftop gardens. These designer soils can be created or altered to meet design specifications or address precise project requirements. Designer soils are often required for rooftop gardens, raised planters, containers and urban tree plantings.
First introduced to the asphalt market over forty years ago, the use of lightweight aggregate in the United States exceeds 3,000 miles of asphalt pavement annually.
