摘要： A system and method for disposing carbon dioxide is disclosed. The system includes a foam generator that generates a plurality of disposable foam vessels from a polymer based solution mixed with water and captured carbon dioxide from the atmosphere. The plurality of disposable foam vessels contains an amount of carbon dioxide. The plurality of disposable foam vessels is mixed in a cementitious material with a set of mixers. In a preferred embodiment, the set of mixers is a concrete mixing plant. During the curing process of the cementitious material the plurality of disposable foam vessels dissipates allowing for a timely release of CO2 to chemically react with the surrounding cementitious material. This irreversible chemistry change permanently disposes of the carbon dioxide.

摘要： Cement compositions and processes for improving the bond between new hydrating cement-based materials and the surface of "old" cement-based substrates are disclosed. A mechanically and chemically integral bond is created between the surfaces of the cement-based materials by moistening the old cement-based surface, exposing the moist surface to carbon or carbonate sources (such as with carbon dioxide) and then applying a new hydrating cement-based material thereon. The treatment of the surface of the cement-based substrate as described above creates an aqueous phase chemistry thereon which is compatible to the aqueous phase chemistry of the hydrating cement-based materials applied thereafter. The compatibility of the aqueous phase chemistries results in a mechanically and chemically integral bond formed between the surface of the old cement-based surface and the hydrating cement-based materials. The bond interface may be characterized by low calcium hydroxide concentrations, the presence of amorphous, noncrystalline material, a low water/cement ratio, greater than 90% of all voids being less than 0.15 mm. in diameter, and a low total air content of the interface. The present invention is particularly applicable to the repairing, resurfacing and topping of existing concrete highways, roads and surfaces.

摘要： Disclosed are formulations adapted to form a foamed cementitious composition, the foamed cementitious composition itself, a method of forming a hydraulic binder foam, and a method of conveying and applying the resulting foam to a substrate. A pumpable cementitious slurry is formed, the slurry is mixed with a gas such as air, and is subjected to mechanically created turbulence to generate gas bubbles and create a foam, which preferably is stabilized by a foam stabilizing agent such as polyvinyl alcohol present in the slurry. The foam is then conveyed to a nozzle or other suitable dispense point from which it is applied, for example sprayed, preferably uniformly, onto a substrate to be coated. Prior to dispensing, a set accelerator is preferably injected, which causes the foam to gel, which in turn improves the hangability of the product on a substrate. The spray material adheres to the substrate and hardens to form an insulative coating on the substrate. Also disclosed are dry compositions comprising a hydratable cementitious binder, a mechanical foam stabilizing agent, and optionally a fibrous component, set retarder and air entraining agent, said composition providing, on the addition of water, gas and mechanical turbulence, a settable foam which is capable of spray application to a steel structural member and which, after spray application, is adherent to the member in the foamed state and after setting. The foam after setting, forms a fire and heat protective adherent coating on the member.
