摘要:
A concrete curing blanket (10) includes an absorbent sheet (22) having a wicking layer (24), super absorbent materials, and a tissue layer (26), which are laminated together to form the absorbent sheet (22). The absorbent sheet (22) is sized for being spread over a curing concrete slab (C). A vapor barrier (30) is bonded to the tissue layer (26) of the absorbent sheet (22) to inhibit evaporation from the concrete curing blanket (10), and includes a plurality of perforations.
摘要:
The invention provides a curing system that is useful for curing materials that consume carbon dioxide as a reagent. The system has a curing chamber that contains the material to be cured and a gas that contains carbon dioxide. The system includes apparatus that can deliver carbon dioxide to displace ambient air upon loading the system, that can provide carbon dioxide as it is needed and as it is consumed, that can control carbon dioxide concentration, temperature and humidity in the curing chamber during the curing cycle and that can record and display to a user the variables that occur during the curing process.

Este panel de mortero de cemento con armadura biaxial pretensada, está constituido por una placa de mortero de cemento que, siendo de un espesor comprendido entre 2 y 7 cm., incluye una armadura biaxial, Ia cual dispone ocluidos en Ia masa del mortero de cemento de unos medios de actuación versátil sobre el conjunto del panel que permiten su manipulación y/o su fijación a Ia estructura de una edificación, los cuales medios de actuación versátil constituyen por sí mismos, por una parte, medios de su retención en Ia masa fraguada del mortero de cemento y, por otra parte opuesta a Ia anterior, medios de anclaje indistinto para unos elementos de manipulación del panel y unos elementos de fijación del mismo a Ia estructura de Ia edificación.
摘要:
The invention encompasses equipment used to condition a recirculating gas stream in order to cure a CO 2 Composite Material (CCM) and processes that use such equipment to cure the CCM. The gas conditioning equipment allows for a process that controls, reduces or eliminates the rate-limiting steps associated with water removal during the curing of a composite material. The equipment may include, but will not be limited to, control over the temperature, relative humidity, flow rate, pressure, and carbon dioxide concentration within the system; which includes the conditioning equipment, any vessel containing the CCM, and the material itself. Flow rate control can be used as a means to achieve uniformity in both gas velocity and composition.

摘要:
A process for producing a honeycomb ceramic article includes providing a green honeycomb body including ceramic-forming materials and organic pore forming materials and subjecting the green honeycomb body to a firing cycle in a kiln in which steam is added to the kiln atmosphere in an amount from about 10 % to about 100 %, based on volume. Also provided are ceramic articles produced by the process.
