Specialty precaster Sonoma Cast Stone has added to its product line an egg-shaped, 500-gal.-capacity fermentation tank. A composite of two distinct mixes, the tank comprises an outer shell of fiber-reinforced, recycled concrete and an inner layer of conventional concrete, creating a 3_-in.-thick wall enclosing a 56?-in.-diameter cavity. Because the face mix Û trademarked as EarthCrete Û is available in a range of colors and finishes, the egg can be produced in various tints without risk of pigmented material coming in contact with the tank’s contents. An optional heating/cooling tubing system embedded in the shell casting maintains the desired temperature.
According to its Petaluma, Calif.-based producer, EarthCrete used in the tanks’ fabrication offers the benefits of concrete, as it surpasses the performance of conventional mixes. Like traditional concrete, the proprietary material conforms to virtually any shape, accepts embedded materials, and provides strength and durability, as well as a warm, organic appearance. Additionally, EarthCrete is environmentally sustainable to an exceptional degree: 21 percent recycled content qualifies for LEED points; and, 60 percent less portland cement is required than for standard-thickness wet cast. Compared to traditional concrete, moreover, its colors are more controllable, air pockets do not form, and longer sections without seams can be achieved. More rapid fabrication also is possible, owing to elimination of steel rebar for reinforcement, simplified form making, and less curing time. Plus, faster production, easier form-making, and less shipping weight contributing to cost effectiveness.
The EarthCrete formula provides the basis as well for Sonoma’s NuCrete, a stainless concrete introduced three years ago. Since it resists discoloration even by lemons, wine, and tomatoes, the producer affirms, NuCrete provides an ideal material for the company’s kitchen countertops. Sustainable benefits include countertops that weigh up to 75 percent less than standard-thickness wet cast, reducing carbon output in both manufacturing and shipping; and, zero river rock content and 87 percent less river and delta sand, minimizing impact on local waterways. Also available from Sonoma Cast Stone are concrete tiles, pavers, custom fireplaces, and bath tubs. Û www.sonomastone.com
