Lightweight Concrete

Lightweight concrete from County Materials is ideal for reducing structural load without compromising performance, and is commonly used in bridge decks, piers, beams, wall elements in multi-story buildings, parking structures, topping slabs, and composite slabs on metal decks. The use of porous aggregates, such as shale, clay, or slate, lowers the density of the mix to 90-115 pounds per cubic foot, compared to normal weight concrete with a density of 140-150 pounds per cubic foot. Lightweight concrete maximizes cost savings and improves thermal properties for foundations, reinforcement, and formwork. The economical advantages of lightweight concrete make it a preferred solution for engineering applications that require lower density as well as strength, durability, and structural integrity.

Lightweight Concrete Offers Exceptional Strength and Durability

Engineers rely on lightweight concrete because it maximizes cost savings for a wide range of applications, from commercial and transportation to residential and multifamily projects.

2026_CMC_Lightweight_Concrete_Building_Components_Application_Image_1

Commercial Developments

Lightweight concrete is made with porous aggregates to lower the overall density of the mix, which reduces costs and improves thermal properties for foundations, reinforcement, and formwork. It uses less reinforcing steel and a lower volume of concrete than standard concrete while maintaining strength, durability, and structural integrity. Lightweight concrete from County Materials is often specified in commercial developments because of its economical advantages.

Parking Structures

Often specified in parking structures because of its economical advantages, lightweight concrete from County Materials is made with porous aggregates to lower the overall density of the mix. This lower density enhances thermal performance in foundations, reinforcement, and formwork while helping reduce construction costs. Lightweight concrete uses less reinforcing steel and a lower volume of concrete than standard concrete while maintaining strength, durability, and structural integrity.

2026_CMC_Lightweight_Concrete_Bridges_Application_Image_1

Bridge Decks and Piers

Lightweight concrete from County Materials contains porous aggregates that decrease the overall density of the mix, which reduces costs and increases the thermal resistance of foundations, reinforcement, and formwork. With more efficient strength-to-weight ratios for smaller load-bearing elements such as footings and columns, lightweight concrete uses less reinforcing steel and a lower volume of concrete while maintaining strength, durability, and structural integrity. Lightweight concrete is often specified for piers and bridge decks.

Transportation Structural Components

Often used for structural components in transportation applications, like bridge decks and piers, lightweight concrete is made with porous aggregates to reduce the overall density of the mix. This lower density saves money while enhancing the thermal performance of foundations, reinforcement, and formwork. Lightweight concrete from County Materials maintains strength, durability, and structural integrity, and needs less concrete and less reinforcing steel than standard concrete does.

The Benefits of Lightweight Concrete

Lightweight concrete is uniquely suited for building and parking structure components such as bridge decks, beams, and wall elements due to a variety of benefits.

Low Material Density

Density ranges from 90-115 pounds per cubic foot, compared to normal weight concrete with a density of 140-150 pounds per cubic foot.

Enhanced Insulation

Porous aggregates such as shale, clay, and slate add to the thermal properties of lightweight concrete.

Reduced Project Costs

Efficient strength-to-weight ratios for smaller load-bearing elements require less reinforcing steel and a lower volume of concrete.

Long-Lasting Durability

Slabs, beams, and other building components made from lightweight concrete will endure decades of stress and wear.

Higher Fire Ratings

Lightweight concrete has fire ratings up to three hours along with higher R-values than standard concrete
