![]() Introducing a new class of materials called semi-cementitious: A smarter, less expensive, faster & better way to build with one-step environmental materials
To builders, wood and cement are old friends, which come together
in WoodBrikTM. For that reason, this new product is both an alternative and a primary building product. Alternative because it departs from what seems conventional, yet primary because it uses some of nature's oldest materials: natural cement called pozzolans, and wood, as waste scraps. The use of such familiar waste byproducts makes WoodBrikTM THE material of choice for earth-friendly yet high quality construction components.
This patented material is described as semi-cementitious because it shows at the same time the virtues of both wood and natural cement in a 100% waste product.
Semi-cementitious products are designed to take the place of wooden studs, concrete block, adobe, man-made insulation, gypsum drywall, and siding in structural walls. With formula changes, other building products such as shingles and panels are feasible, and under development.
With such multiple functions, semi-cementitious material has the effect of signficantly reducing pressure on the world's environmental resources. Its use can:
Developed by Midway Environmental Associates, Inc., of Arvada, Colorado, products fabricated from such material can be nailed, screwed and sawed like wood, yet they are formed and harden like concrete. They are lightweight, weather and water resistant, self-insulating, noncombustible, and capable of bearing significant structural loads.
Semi-cementitious material can be molded into interlocking shapes and be assembled without mortar (walls being bolted from foundation through top plate). Chief among Midway's semi-cementitious products is the tradename, WoodBriktm, a block which comprises an exterior wall system which is less expensive in finished form than any other system now in use.
The controlling U.S. patent, "Structural Products Manufactured From Fly Ash," was issued July 9, 1996, as patent No. 5,534,058.
