20110126737 | METHOD FOR RECYCLING OILY WASTE IN ORDER TO PRODUCE A MULTI-USE DRY-TYPE MODIFIED PAVEMENT - The invention relates to a treatment process or recycling co process for oily wastes originating from the use of hydrocarbons, products manufactured therefrom and derivatives of same, without using aggregates from natural banks during the transformation process, thereby producing a novel material which can be used as an aggregate in hydraulic or asphaltic rolling surfaces, road sub-bases, bases and repair work involving cold patching, and which has the following mechanical characteristics and properties: zero plasticity; non toxicity; insolubility and impermeability to water, which prevents any form of leaching during the handling or use thereof; and optimum CBR and compacting, reducing construction times and costs and any negative impact on the environment, through the sustainable use of wastewater streams. | 06-02-2011 |
20110155020 | SYSTEM AND METHOD FOR MAKING CEMENT AND CEMENT DERIVED THEREFROM - Integrated cement production systems and methods implementing the systems are disclosed, where the integrated cement production systems include a burnable fuel supply subsystem, a cement raw material supply subsystem, a kiln subsystem and a cement clinker composition storage subsystem. The burnable fuel supply subsystem is adapted to receive one or a plurality of used and/or unused healthcare materials. The burnable fuel supply subsystem can feed the materials directly into the kiln subsystem, can convert the materials into different form and feed the different form to the kiln subsystem or feed a combination of the materials, different forms and optionally conventional fuels to the kiln subsystem. | 06-30-2011 |
20130139729 | Providing Freeze-Thaw Durability to Cementitious Compositions - A cementitious freeze-thaw damage resistant composition includes hydraulic cement, and coffee grounds particles having a volume-weighted mean particle size of from greater than 50 μm to about 2000 μm. A method for preparing a freeze-thaw damage resistant cementitious composition includes forming a mixture of water, hydraulic cement, and coffee grounds particles having a volume-weighted mean particle size of from greater than 50 μm to about 2000 μm. The coffee grounds particles act to increase the freeze-thaw durability of the cementitious material. A cementitious freeze-thaw damage resistant composition comprising hydraulic cement, and organic particles comprising at least one of coffee grounds particles, leaf powder particles, starch microcontainers, ground tea leaf particles, or cork powder particles. | 06-06-2013 |
20140026787 | COMPOSITION FOR ADVANCED HYBRID GEOPOLYMERIC FUNCTIONAL MATERIALS AND A PROCESS FOR THE PREPARATION THEREOF - The present invention provides a composition for advanced hybrid geopolymeric functional materials possessing very broad application spectrum ranging from cementitious materials to advanced functional materials having “Inorganic-Organic Hybrid” matrix in contrast to the limited application of conventional geopolymeric materials having “Inorganic matrix” only. The invention further relates to a process for the preparation of these materials. The process obviates the need of external addition of sodium silicate which is one of the costliest and main raw materials in conventional geopolymerisation processes. Interestingly, in the present invention the sodium silicate has been synthesized in situ by designing of conditions for synergistic and simultaneous mechano-chemical reactions among the selected raw materials viz. inorganic and organic wastes under alkaline environment. This results in the formation of “Hybrid inorganic-organic frame work” of sodium silicate, which facilitates uniform dispersion of reacting species, thus resulting in the formation of homogeneous geopolymeric matrix with improved characteristics. | 01-30-2014 |
20140130715 | METHOD FOR FORMING PRODUCTS FROM A FLUE GAS DESULFURIZATION BY-PRODUCT AND PRODUCTS FORMED THEREBY - Compositions and methods for producing a manufactured product, a method for making a liquid absorbent, and processes for disposal of flammable liquids with a flue gas desulfurization by-product. The compositions for the manufactured products combine a binder and the by-product. The composition contains a greater percentage by weight of the by-product than the binder. The methods for producing manufactured products include dewatering the gypsum-depleted waste stream to reduce a water content, and forming the manufactured product. The method for making a liquid absorbent includes dewatering, granulating, drying, heating, and packaging a granulated gypsum-depleted composition as the liquid absorbent. The processes for disposal of flammable liquids include distributing a by-product into contact with flammable liquid, absorbing the liquid, transporting, and igniting the flammable liquid. The artificial soils are a combination of by-product and animal waste, human waste, or another bio-solid. | 05-15-2014 |
