The pressurized air draws stucco from the container into the flow conduit, and also draws water into the flow conduit to form an atomized slurry. | 10-22-2015 |
| 20150299041 | ADDITION OF COLLOIDAL SILICA TO CONCRETE - A method of blending concrete is provided wherein there is a determination of a standard volume of water to add to a dry concrete mix to provide hydrated concrete with a desired slump value, and then calculating a substitution volume of an aqueous composition including colloidal silica to be used in place of an eliminated portion of the standard volume of the water, and mixing the substitution volume of the aqueous composition with the concrete mix. | 10-22-2015 |
| 20150353423 | METHOD FOR MANUFACTURING HIGH-STRENGTH CEMENT CURED PRODUCT - A method for manufacturing a high-strength cement cured product constituted by: mixing and kneading cement with at least water and water-reducing agent; patting the cement kneaded mixture ( | 12-10-2015 |
| 20150361665 | Three-Dimensionally Deformed Fiber for Concrete Reinforcement - A concrete reinforcing member for admixture into a concrete composite. The concrete reinforcing member has a body extending in a longitudinal direction along an axis, the body having a lateral width. At least two anchor segments are axially spaced on the body, each anchor segment having at least one lateral extension projecting in a lateral direction along an associated plane that extends radially relative to the axis of the body. The associated plane of the lateral extension of one of the anchor segments is offset radially about the axis at an angle of greater than 0° and less than 90° relative to the associated plane of the lateral extension of the other anchor segment. | 12-17-2015 |
| 20160046039 | Method and System for Fabrication of Elongate Concrete Articles - A method for fabricating an elongate concrete article including introducing a concrete mix having a relatively high water to cement ratio into a fabrication assembly, the fabrication assembly including a core assembly and an outer mould. The method then involves dewatering in a first stage the concrete mix as it is pumped into a mould cavity formed between the core assembly and the fabrication assembly to reduce the water to cement ratio and then dewatering in a second stage the concrete mix after the mould assembly has been filled to further reduce the water to cement ratio. | 02-18-2016 |
| 20160051962 | SONIC REACTOR - A sonic reactor for transferring kinetic energy to a process fluid medium has a resonant element horizontally oriented and mounted to the two resonance units using two or more nodal support rings located at the nodal positions of the resonant element. The nodal support rings are adjustable in position relative to the resonant element and the resonance units to permit positioning of the rings directly at the nodal positions during operation, where, for example, adjustment may be required due to changes in the total mass attached to one or both free ends of the resonant unit. The sonic reactor has a grinding or mixing chamber mounted at one or both of the free ends of the resonant element. | 02-25-2016 |
| 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 |
