A dry pulverulent ash composition is described which comprises a dry pulverulent fly ash to be used as a portland cement substitute for improving the physical properties of a finished concrete product. The ash composition includes fly ash together with an oxidizer present in a dry pulverulent form that is unreacted with the ash and is maintained in an unreacted state during shipment and storage but is capable of reacting with the fly ash upon an addition of water to convert virtually all and preferably over 95% of the sulfur compounds present in the ash to the sulfite form. The oxidizer is present in minor amount from about 0. 5% to about 10% by weight of the composition. An aggregate comprising pellets can also be added to the composition together with a minor amount of portland cement and a conditioner e. g. , accelerator to form a concrete block product that is up to 10% lighter than a standard concrete block that does not use the present composition and at the same time exhibits improved crushing strength. A method of forming the ash composition is also described.

The invention provides a novel formed product and method of producing a hard, dry, e. g. , agglomerated or formed, product useful as a construction material comprising: a) papermill sludge made up of paper fiber, clay and calcium carbonate, b) ash such as coal ash (typically stack scrubber solids obtained from the burning of coal), and c) water. The amount of water present is selected to render the product plastic so that it can be molded to the desired shape. An oxidizer is provided in a sufficient amount to oxidize unstable compounds and to convert potassium, calcium or magnesium bisulfite to the sulfate form. Following the addition of the oxidizer, the admixture is exposed to electromagnetic energy, preferably ultraviolet light, to help drive the oxidation reaction to completion. In an optional form of the invention, a minor amount of a cation exchange resin is added to the mixture to sequester heavy metals. The admixture is formed or molded into pieces or bodies of the desired shape, such as blocks, slabs or pellets or agglomerates.

The invention provides a novel, environmentally stabilized formed product and to a method of producing a hard, dry, e. g. , agglomerated or formed, environmentally stabilized product useful as a construction material, e. g. , as pellets, panels, bricks, etc. comprising: a) ash such as RDF or coal ash (typically stack scrubber solids or bottom ash obtained from the burning of coal), b) an oxidizer and c) water. The amount of water present is selected to render the product plastic so that it can be molded to the desired shape. The oxidizer is provided in a sufficient amount to oxidize unstable compounds and to convert potassium, calcium or magnesium bisulfite to the sulfate form. Following the addition of the oxidizer, the admixture is exposed to electromagnetic energy, preferably ultraviolet light, to help drive the oxidation reaction to completion. In an optional form of the invention, portland cement, plaster of paris or a minor amount of a cation exchange resin or Zeolite clay is added to the mixture to sequester heavy metals. The admixture is formed or molded into pieces or bodies of the desired shape, such as blocks, slabs, pellets or agglomerates.

A nontoxic and environmentally compatible insect control, e.g., a liquid spray, for eradicating insects includes an aqueous solution or dispersion of a surfactant that is present in a sufficient amount to debilitate or kill the insects and a thickener. The surfactant can be any synthetic detergent such as sodium lauryl sulfate and the thickener is preferably a water soluble or dispersable thickening agent. Optional components include a source of biocompatible cations, a salt and preservative. A method is disclosed for releasing an insect control composition when the insect is sensed, e.g., by means of a microphone and for attracting the insect to the microphone or other sensing means.

Producing both colored and noncolored lightweight aggregates. The processes involve mixing a lightweight fine material such as ash with cement, and optionally pigment, then agglomerating the mixture, curing, and sizing the lightweight aggregate. Calcium stearate is added to the lightweight aggregate for reducing the moisture permeability of the lightweight aggregate end product. The colored and noncolored lightweight aggregate may be used in a variety of ways such as to provide a lightweight concrete mix with the same exterior and interior color, and for other asphalt pavement, geotechnical, horticulture, and specialty uses.
