20150210594 | METHOD FOR PRODUCING AGGREGATE AND CALCIUM CARBONATE FROM CONCRETE COMPOSITE MATERIALS, AND A DEVICE FOR CARRYING OUT SAID METHOD - The invention relates to a method for producing aggregate and calcium carbonate from concrete aggregate, and a device for carrying out said method. | 07-30-2015 |
20140033638 | REINFORCED WALL SYSTEM AND METHOD - A method of constructing a wall to meet an applicable building code, and a wall created by this method. The method may include placing insulating concrete forms, having a cavity, where the wall is to be constructed; placing a limited quantity of metal reinforcement steel within the cavity, such that the limited quantity of reinforcing steel is insufficient to meet the applicable building code; and pouring a mix of aggregate, sand, cement, fly ash, and mineral fibers into the cavity; and allowing the mix to cure, thereby meeting the applicable building code without additional metal reinforcement. The mix may between 45 and 50% stone, between 30 and 35% sand, between 10 and 12% Portland cement, between 5 and 8% fly ash, between 1 and 2% mineral fibers, and between 0 and 1% admixtures by weight. The mix may contain mineral fibers of different grades and/or dimensions. | 02-06-2014 |
