20140116295 | CARBON DIOXIDE TREATMENT OF CONCRETE UPSTREAM FROM PRODUCT MOLD - Fresh concrete is treated with carbon dioxide prior to delivery to a product mold for forming concrete products. Carbon dioxide gas is directed through a manifold, which may be coupled to a feedbox or a hopper, upstream from the product mold. Treating the fresh concrete with the carbon dioxide gas while it is in a loose state prior to placement in the product mold may generally promote uniform and enhanced carbon dioxide uptake. | 05-01-2014 |
20140197563 | CARBON DIOXIDE SEQUESTRATION IN CONCRETE ARTICLES - Concrete articles, including blocks, substantially planar products (such as pavers) and hollow products (such as hollow pipes), are formed in a mold while carbon dioxide is injected into the concrete in the mold, through perforations. | 07-17-2014 |
20140327168 | CARBON DIOXIDE TREATMENT OF CONCRETE UPSTREAM FROM PRODUCT MOLD - Fresh concrete is treated with carbon dioxide prior to delivery to a product mold for forming concrete products. Carbon dioxide gas is directed through a manifold, which may be coupled to a feedbox or a hopper, upstream from the product mold. Treating the fresh concrete with the carbon dioxide gas while it is in a loose state prior to placement in the product mold may generally promote uniform and enhanced carbon dioxide uptake. | 11-06-2014 |
20140373755 | METHODS AND COMPOSITIONS FOR CONCRETE PRODUCTION - The invention provides compositions and methods directed to carbonation of a cement mix during mixing. The carbonation may be controlled by one or more feedback mechanisms to adjust carbon dioxide delivery based on one or more characteristics of the mix or other aspects of the mixing operation. | 12-25-2014 |
20150197447 | Compositions and Methods for Delivery of Carbon Dioxide - Compositions and methods are provided for a system in which liquid carbon dioxide, or a mixture of liquid and gaseous carbon dioxide, is converted to solid carbon dioxide by exiting an orifice at a sufficient pressure drop, e.g., for delivery of carbon dioxide to a concrete mixture in a mixer. | 07-16-2015 |
20150232381 | METHODS AND COMPOSITIONS FOR CONCRETE PRODUCTION - The invention provides compositions and methods directed to carbonation of a cement mix during mixing. The carbonation may be controlled by one or more feedback mechanisms to adjust carbon dioxide delivery based on one or more characteristics of the mix or other aspects of the mixing operation. | 08-20-2015 |
20160001462 | APPARATUS FOR CARBONATION OF A CEMENT MIX - The invention provides compositions and methods directed to carbonation of a cement mix during mixing. The carbonation may be controlled by one or more feedback mechanisms to adjust carbon dioxide delivery based on one or more characteristics of the mix or other aspects of the mixing operation. | 01-07-2016 |
20160107939 | METHODS AND COMPOSITIONS FOR CONCRETE PRODUCTION - The invention provides compositions and methods directed to carbonation of a cement mix during mixing. The carbonation may be in a stationary mixer or a transportable mixer, such as a drum of a ready-mix truck. | 04-21-2016 |
