Specialty
White Stone Calcium’s rock and sand are key ingredients in architectural and decorative concrete. Our popular China White aggregate, regularly chosen for its brilliant appearance, is both functional and beautiful. Benefits include:

■ energy efficiency
■ low maintenance
■ high durability
This type of highly light reflective flooring is well suited for large buildings, providing cost effective benefits.

The high grade inherent in our white aggregate when mixed with white cement has the added benefit of early strength and faster set (about 3,000 psi at 3 days, with ultimate strengths of 6,000 pounds per square inch).

Other uses for our specialty rock products:

■ epoxy stone applications
■ tile
■ roof tiles
■ landscapes
■ retaining walls
■ building accents
■ sidewalks and driveways
■ interior and exterior flooring
■ exposed aggregate

■ pools and decks
■ counter tops
■ municipal
■ masonry
