| 181 | IN SITU PRECIPITATION OF CALCIUM CARBONATE (CACO3) BY INDIGENOUS MICROORGANISMS TO IMPROVE MECHANICAL PROPERTIES OF A GEOMATERIAL | EP10806729.9 | 2010-05-28 | EP2462232A2 | 2012-06-13 | CRAWFORD, Ronald, L.; BURBANK, Malcolm, B.; WEAVER, Thomas, J.; WILLIAMS, Barbara, C. |
| A method for increasing the concentration of calcium carbonate in a geomaterial that contains indigenous microorganisms capable of hydrolyzing urea to ammonia, which method includes enriching the geomaterial with a source of nutrients, adding urea to the geomaterial which is hydrolyzed to ammonia and which raises the pH of the geomaterial, and adding a source of calcium ions to the geomaterial. Carbonate ions obtained by the hydrolysis of the urea combine with calcium ions to form calcium carbonate. | ||||||

| A process is disclosed for producing cement clinker, comprising the steps of: a) providing a mixture of ground calcareous materials and ground argillaceous materials; b) heating the mixture of step a) to a temperature sufficient to calcine and fuse the ground materials to form the cement clinker, and thereby producing an exhaust gas containing CO2; c) catalysing the hydration of at least a portion of the CO2 contained in the exhaust gas and producing a solution containing bicarbonate ions and hydrogen ions; and d) adding to the solution obtained in step c) metal ions, and adjusting the pH of the solution to precipitate a carbonate or said metal. Preferably, the metal ions are Ca++ obtained from the dissolution of a material selected from the group consisting of CaCl2, cement kiln dust and sea salts and the carbonate is CaCO3 which is advantageously recycled into the process by adding the CaCO3 to the mixture of step a). A cement plant for performing this process is also disclosed. | ||||||

| 188 | HEALING AGENT FOR SELF-HEALING CEMENTIOUS MATERIAL | PCT/NL2011000026 | 2011-04-06 | WO2011126361A8 | 2012-10-11 | JONKERS HENDRIK MARIUS |
| The invention provides a process for the production of a cementious material. The process comprises mixing cement starting materials and a particulate healing agent to provide the cementious material. The healing agent comprises coated particles, wherein the coated particles comprise bacterial material and additive. The bacterial material is selected from the group consisting of a bacterium, a lyophilized bacterium and a bacterial spore of a bacterium. The present invention solves these problems, as (substantially leakage-proof) tablets containing the actual healing agent may neither interfere with either the workability of the liquid mixture ("cementious material") nor negatively affect properties of either mixture or final material (hardened concrete), even when applied in large quantities. During crack formation in cementious based constructions, the particles also crack, and healing agent is released. | ||||||

| The present invention relates to a method for producing a sand aggregate, comprising: (a) a step of producing organic waste powders or by-product powders; (b) a step of mixing the organic waste powders or the by-product powders produced in step (a) with soil microbes; (c) a step of mixing the resulting material obtained in step (b) with sand to inoculate the sand with the soil microbes; and (d) a step of supplying water to the resulting material obtained in step (c), and aggregating particles of the organic waste powders and the sand by the growing mycelia of the soil microbes. The present invention produces a sand aggregate (preferably, sand cake, precast pavers or bricks, etc.) or reforms (preferably, fertilizes) sand using organic waste (or by-products), to reutilize waste (or by-products) and to thus prevent soil or water from being contaminated by organic waste (or by-products). Further, when the present invention is applied to the sand in which plants grow poorly, the sand is fertilized to promote the growth of symbiotic microorganisms, and to raise plants and suppress the use of chemical fertilizers and agricultural pesticides, thus activating environmentally-friendly green farming. Meanwhile, when the present invention is applied to the desert of China, which causes yellow dust storms, sand and red clay are provided with anti-scattering properties, to thereby prevent yellow dust storms and environmental contamination and damage to animals and plants caused by the yellow dust storms. | ||||||

| 199 | Zusatzmittel für zementgebundene mineralische Baustoffe, insbesondere für Estriche | EP08020353.2 | 2008-11-22 | EP2090552A3 | 2010-03-31 | Mertens, Antonius |
Die Verwendung eines Zusatzmittels für mit Zement oder Kalk gebundene mineralische Baustoffe wie Estrich, Beton, Putz, Spachtelmasse etc., das dem Anmachwasser beigemischt wird, ist dadurch gekennzeichnet, dass es eine fermentierte EM (Effektive Mikroorganismen nach Prof. Dr. Teruo Higa) enthaltende Lösung aufweist. Die aus dem Anmachwasser und dem zugegebenen EM-Zusatzmittel gebildete flüssige Mischung bewirkt nach Durchmischung des Sandes mit dem Zement und dem Anmachwasser, dass sich innerhalb der ersten Hydratationsphase des Zementes CO2 bildet, welches das Überschusswasser heraustreibt. Die Trocknung tritt sehr schnell ein, wobei eine verlegte Estrichfläche praktisch keiner Verformung unterliegt. Die Trocknungsspannungen sind so gering, das wesentlich größere Flächen in einem zusammenhängenden Bereich ausgeführt werden können. |
