| 20080264303 | SOLID SURFACE PRODUCT CONTAINING ORIENTED REFLECTIVE PARTICLES AND METHOD OF MAKING SAME - A solid surface material which exhibits a pearlescent visual appearance and method of making it are provided. The solid surface material includes a polymer resin, optionally, a filler, and oriented anisotropic pigment particles dispersed substantially throughout the polymer resin to provide the pearlescent visual appearance. The solid surface material is made by forming a mixture of polymer resin, optional filler, and anisotropic pigment particles; dispersing the pigment particles substantially throughout the mixture; casting the mixture into an open mold; applying a vacuum to the molded mixture to release entrapped gases therein to cause the pigment particles to become oriented in the mixture; and curing the molded mixture to produce the solid surface material. | 10-30-2008 |
| 20080314296 | MANUFACTURED CONSTRUCTION BOARD WITH IMPROVED CHEMISTRY - A manufactured construction board is formed from a composition that may include magnesium oxide, magnesium chloride, a binding agent (e.g., perlite), wood shavings, recycled board scraps, and water. The construction board further includes fiberglass and polyester paper sheets on opposite sides of the construction board. A method of fabricating the construction board is also disclosed to include mixing magnesium chloride with water to form a solution, mixing the solution with magnesium oxide, perlite and a binding agent to form a paste, and pouring the paste onto a mold to form a construction board. The paste is poured onto a mold which is then passed through a series of rollers to spread out the paste evenly across the mold and to form the paste into the desired thickness. The resulting construction board is fire and water resistant and much more durable than conventional sheetrock. | 12-25-2008 |

| 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 |
