20140096704 | MAGNESIUM PHOSPHATE CEMENT - Magnesium phosphate cement binder systems and method for providing magnesium phosphate cements are described. In an embodiment, a magnesium phosphate cement binder system may include magnesium oxide that has been calcined at a temperature of between about 900° F. to about 1800° F. The magnesium phosphate cement binder system may also include a phosphate material. Other formulations, compositions, and methods are also described. | 04-10-2014 |
20130264290 | IMPROVING WASTEWATER PUMPING AND CONVEYING EFFICIENCY - Methods and systems for improving pumping or conveyance efficiencies of wastewater within a wastewater treatment system of described. In an embodiment, an effective amount of a magnesium compound may be added to wastewater within a wastewater treatment system to increase at least one of a pumping and a conveyance efficiency of the wastewater within at least a portion of the wastewater treatment system. In an embodiment, the method may also include measuring at least one or the pumping efficiency and the conveyance efficiency of the wastewater within the portion of the wastewater treatment system. A concentration of the added magnesium compound may be adjusted to increase at least one of the pumping and the conveyance efficiency within the portion of the wastewater treatment system. Other methods and systems are described. | 10-10-2013 |
20130115835 | Light Weight Magnesium OxyChloride Composition and Construction Board - A high performance, light weight construction board includes unique low solids Magnesium Oxychloride binder systems filled, Expanded Polymer Beads (EPB) blended with Expanded Perlite and/or with Coal Fuel Fly Ash. Weight reductions for such compositions by incorporating proteinaceous foaming agents into the binder matrix. The use of Calcium and other alkali earth chlorides mixed with magnesium chloride, or totally replacing magnesium chloride, provides unexpected improvements in binder strength. The use of a unique polymer scrim with felt construction provides improved compressive and directional strength properties while also providing superior board pull and shear properties. | 05-09-2013 |
20120298012 | Admixtures for Shrink Crack Reduction of Portland Cement-Based Mortars and Concretes - Portland Cement-based concretes and mortars exhibit significant reduction in shrinkage cracking when combined with Magnesium Oxide (MgO), Shrinkage Reduction Admixtures (SRA) and Super Absorbent Polymers (SAP). However, MgO is a solid that reacts with water, SRA is a liquid, and SAP if not added properly could pull water out of the system and thus increase shrinkage. Unique admixture blends used as supplementary cementing materials that do not significantly affect concrete or cement strength properties of Portland cement itself address such issues. Proper ratios of MgO, SRA and/or SAP perform better against crack reduction when compared to commonly used Expansive Cements (EC). | 11-29-2012 |
