Abstract: A red brick comprising waste foundry sand of 30.about.50 wt %, dusts of 5.about.10 wt %, and a remainder of clay. The waste foundry sand and dusts can be efficiently recycled, and the quantity of the sand used, the supply of which sand which is nearly exhausted, can be reduced. The heating temperature in the red brick manufacturing process is remarkably lowered, and the economical efficiency of the manufacturing process is improved greatly by using iron oxide included in dusts, instead of a chemical compound to obtain desired color.

Abstract: Processes for treating fly ash to enhance the fly ash as a pozzolan for portland cement mixes and to separate therefrom a substantial carbon compound and/or to increase the fineness of the fly ash include the treatment of a fly ash slurry with ultrasonic energy using ultrasonic horns immersed in a slurry of fly ash and water and imparting to said slurry such ultrasonic energy as to cause microscopic cavities to form and implode with high localized energy to break up fly ash agglomerations along cleavage lines and to break up carbon particles and matrices which have entrapped fly ash microspheres therein to release the microspheres into the slurry. A conditioner agent may be added at or during ultrasonic treatment to enhance the flotation of the carbon compound.

Abstract: A method for improving the pozzolanic character of fly ash includes the steps of first hydraulically classifying and then flotation separating the fly ash in order to reduce particle size distribution and remove carbon. The method also includes the steps of spiral concentrating separated coarse particles to recover iron, pyrite and marcasite and screening the fly ash to remove ultra-light carbon and plant debris.

Abstract: The present invention relates to concrete, mortar and other hardenable mixtures comprising cement and fly ash for use in construction. The invention provides a method for increasing the rate of strength gain of a hardenable mixture containing fly ash by exposing the fly ash to an aqueous slurry of calcium oxide (lime) prior to its incorporation into the hardenable mixture. The invention further relates to such hardenable mixtures, e.g., concrete and mortar, that contain fly ash pre-reacted with calcium oxide. In particular, the fly ash is added to a slurry of calcium oxide in water, prior to incorporating the fly ash in a hardenable mixture. The hardenable mixture may be concrete or mortar. In a specific embodiment, mortar containing fly ash treated by exposure to an aqueous lime slurry are prepared and tested for compressive strength at early time points.

Abstract: Solid residues obtained in flue gas purification, in particular flue dusts, are disposed in an environmentally compatible and economical manner by acid extracting heavy metals from the residues, precipitating the heavy metals from the extract, separating the precipitate from the mother liquor, subjecting the precipitate containing heavy metals to mechanical stress during which procedure the water contained in the precipitate is released and the precipitate itself is resuspended, and then adding a hydraulic binder to the resuspended precipitate containing heavy metals and/or to the extracted residues separately from one another. The binder-containing mixture can be used to form moldings which, after hardening, are employed for the erection of boundary walls in a landfill, Additionally or alternatively, the plastic binder-containing mixture can be introduced in the form of layers into preformed landfill spaces, where it then hardens.

Abstract: A hydrated granular fly ash composition is disclosed. The granular fly ash may be transported with minimal dust problems while maintaining its capacity to act as a solidifying agent at a remote destination. The process for producing the fly ash involves evenly dispersing a pre-determined amount of water into the fly ash so that it is transformed into a granular form substantially eliminating dust production. An apparatus for processing the fly ash includes a hopper for receiving the fly ash, a conveyor and a modified conditioner in which the fly ash is hydrated.

Abstract: Methods and apparatus for reducing the carbon content of fly ash are disclosed. The fly ash is subjected to an inclined surface having first and second vibratory sources for respectively moving the fly ash from the elevated end of the incline to the lower end and to disaggregate and stratify a high carbon fraction from an enhanced fly ash fraction. The second vibratory source, in combination with the inclined surface, separates the lighter, high carbon fraction while the heavier enhanced fly ash fraction travels toward the lower end of the incline. An air jet and associated vacuum draft pull the high carbon fraction from the incline, leaving the enhanced fly ash portion for use, after removal from the surface, as an example, as acceptable mineral admixture for use in Portland Cement concrete.

Abstract: The invention provides a process for producing a ceramic product for use as a construction material. According to the process of the invention, 2 to 50% by weight, based on the total weight, of sludge ashes containing 0.3 to 0.8 mole of CaO in Seger formula, 0.1 to 0.5 mole of MgO in Seger formula, and 0.2 mole or more of P.sub.2 O.sub.5 in Seger formula is added to a ceramic raw material. A desired percentage can be selected from the range of 2 to 50% to produce a ceramic product with desired properties. Also, according to the invention, a molded body can be fired at a temperature lower than a temperature used to fire a molded body with no sludge ashes to produce a ceramic product which is comparable to a ceramic product produced by firing the latter molded body. That is, according to the invention, a molded body can be fired at a temperature of 900.degree. to 1,200 .degree. C. to produce such a ceramic product.

Abstract: A method of disposing of salt-containing dusts from incinerator plants by mixing salt-containing dusts, having approximately 1% or less of lime with cement and water. The amount of cement in the mixture is between 3% and 25% of the total mixture. The amount of hydrothermally reactive powdered components is not less than 8% of the total mixture. The mixture is compacted into discrete compacts, and hardened in an autoclave by saturated steam with a pressure of at least 1 bar to form stable compacts.
