| 61 | Magnesium Oxychloride Cement | US11936717 | 2007-11-07 | US20080145550A1 | 2008-06-19 | George Eccles Caine; Charles W. Ellis |
| Magnesium oxychloride cement is formed by mixing a magnesium chloride (MgCl2) brine solution with a magnesium oxide (MgO) composition in a selected stoichiometric ratio of MgCl2, MgO, and H2O that forms the 5 phase magnesium oxychloride cement composition. Although Sorel cements formed from the mixture of MgCl2, MgO can form a variety of compounds, the inventive systems and methods provide for controlling the cement kinetics to form the five phase magnesium oxychloride cement composition and results in an improved and stable cement composition. Various fillers can be optionally added to form preferred cement materials for uses as diverse such as road stripping, fire-proofing, fire barriers, cement repair, and mortar. | ||||||
| 62 | Composition for controlling wellbore fluid and gas invasion and method for using same | US10297752 | 2003-03-13 | US20040040711A1 | 2004-03-04 | Brian Henry Tomlinson |
| The disclosure is directed to a composition for controlling wellbore fluid and gas invasion including methods for using said composition. The composition of the invention is a flowable slurry preferably comprising about 70 to 30% by weight of magnesium oxychloride and about 70 to 30% by weight of water. The composition is a flowable slurry at composition temperatures below about 60null C. and sets to form a substantially solid mass upon reaching a composition temperature of about 60-68null C. The phase transition is rapid, thereby limiting or avoiding formation of gel states which contribute to incomplete wellbore seals. The rapid set of the slurry further avoids invasive contamination of earthen formations surrounding the wellbore. The composition has a near-linear relationship between the time required for the phase transition to occur and the composition temperature at which the phase transition occurs. This advantageous property permits the composition set time to be accurately determined and modified as required through the addition of accelerators and inhibitors. The phase transition occurs predictably at high pressures typical of those encountered in wellbore operations. Additives may be included to modify the properties of the composition. The method includes use of the composition to control the loss of fluids and gases from the wellbore. | ||||||

| 64 | Preparing magnesium oxychloride and/or oxysulfate cements | US937297 | 1978-08-28 | US4158570A | 1979-06-19 | Robert G. Irwin |
| A method of preparing magnesium oxychloride and/or oxysulfate cements is described which involves the control of temperature of the magnesium chloride and/or sulfate solutions and the magnesium oxide used to prepare the cements during mixing and the controlled addition of the requisite amounts of magnesium oxide, magnesium chloride and/or sulfate required to form the cements during the mixing procedure. In mixing the requisite oxides with the sulfate and/or chloride solutions used to produce the cement mixtures, the oxide is mixed and thoroughly blended with at least 80 percent of the requisite chloride and/or sulfate solution required to provide a homogeneous mixture. After achieving the initial homogeneous mixture, the balance of the chloride and/or sulfate solution required to provide the requisite chemical constituents to form an oxychloride or oxysulfate cement is added and thoroughly blended to provide a second homogeneous mixture capable of forming a magnesium oxychloride or magnesium oxysulfate cement product upon setting. | ||||||

| Indoor brick, tile or siding, light-weight, fire-resistant, light-fast, non-curling and easy to install. The product is made of a composition of magnesium oxychloride binder, a main filler of particulate non-metallic material in the nature of finely divided vegetable or inert mineral material and a pigment filler in the nature of metallic oxides. The magnesium oxychloride is a reaction product of magnesium chloride and magnesite in a water medium, the magnesium chloride prior to the reaction having been present (on a dry weight basis) to the magnesite of from about 70 percent to about 100 percent. The main filler is present in an amount of from about 150 percent to about 250 percent (on a dry volume basis) to the magnesite. The pigment filler is present in an amount of from about 17 percent to about 80 percent to the magnesite calculated as substantially dry weight basis. The product is made by preparing a solution of magnesium chloride of from 15* to 25* Baume, adding to the solution the pigment filler, adding magnesite, adding the main filler, mixing the resulting composition to form a paste, pouring the paste into a mould in a layer, if desired dividing the layer into sections, and allowing the resulting product to harden.

| The invention relates to a novel composite for forming pre-fabricated building elements, as well as a method of using the composite to mould new building elements. The composite comprises a combination of organic and inorganic material mixed with a binder and a catalyst. The volumes in which each element of the formulation is added depends on which specific element is being formed - the formulation may for instance differ between a building block and a pre-cast wall or a floor tile. The mould used to in the method to manufacture building elements comprising the novel composition contains one or more sheets of fiberglass in a specific shape. | ||||||
