Acoustically Diffuse & Absorbent Lightweight Aerated Concrete
ADALAC—Acoustically Diffuse & Absorbent Lightweight Aerated Concrete, receives Architect R+D Award
“Designed for use on walls and ceilings, ADALAC panels can reflect, diffuse, and absorb sound frequencies related to everyday speech. Designers and manufacturers often address acoustical needs with materials that provide either absorption or diffusion, but not both”, says Daniel Butko, AIA, associate professor of architecture at OU’s Christopher C. Gibbs College of Architecture. The panels are formed in a modular sawtooth pattern and made of concrete with a powdered aluminum admixture, that reacts to produce hydrogen gas. The gas bubbles create pockets and voids in the concrete as it sets. This process gives the concrete panel a significantly better absorption coefficient. This project is by Daniel Butko and his collaborators, including Zachary Maggia, AIA (TAP).
