Aggregate in Concrete - The Concrete Network

Aggregates are generally thought of as inert filler within a concrete mix. But a closer look reveals the major role and influence aggregate plays in the properties of both fresh and hardened concrete. Changes in gradation, maximum size, unit weight, and moisture content can all alter the character and performance of your concrete mix.

Design Ideas for Exposed Aggregate - The Concrete Network

Broadcast decorative polished glass, stone, or luminescent material into the concrete to achieve a shimmery effect. Incorporate a stamped pattern or artistic design into the concrete by imprinting the design while the concrete is still pliable and then exposing the aggregate around it once the concrete is hard enough to withstand washing.
