Methods for the manufacture of sheets having a highly inorganically filled organic polymer matrix
Compositions and methods for manufacturing sheets having a highly inorganically filled matrix. Suitable inorganically filled mixtures are prepared by mixing together an organic polymer binder, water, one or more inorganic aggregate materials, fibers, and optional admixtures in the correct proportions in order to form a sheet which has the desired performance criteria. The inorganically filled mixtures are formed into sheets by first extruding the mixtures and the passing the extruded materials between a set of rollers. The rolled sheets are dried in an accelerated manner to form a substantially hardened sheet, such as by heated rollers and / or a drying chamber. The inorganically filled sheets may have properties substantially similar to sheets presently made from traditional materials like paper, cardboard, polystyrene, plastic, or metal. Such sheets can be rolled, pressed, scored, perforated, folded, and glued. They have especial utility in the mass production of containers, particularly food and beverage containers.

A method and apparatus for supplying bulk material to an end user includes the step of providing a bulk material source that is at a location distant from the end user and a specially configured vessel and trailer apparatus for transporting the bulk material to the end user. The vessel is filled with bulk material at the bulk material source and then transported with a specially configured trailer. Alternatively, at source or destination, the vessel can remain as a temporary storage device, free-standing from the trailer. During transport between the bulk material source and the end user, the vessel is filled or partially filled with a selected bulk material. During transport, the vessel is in a generally horizontal position, supported by the trailer and a specially configured elevator. The vessel is unloaded from the trailer by moving the vessel longitudinally along the trailer and by transferring the vessel from a generally horizontal position upon the trailer to an elevated upright position.

Method for adjusting concrete rheology based upon nominal dose-response profile

The invention relates to a method for adjusting concrete rheology requiring only that load size and target rheology value be selected initially rather than requiring inputs into and consultation of a lookup table of parameters such as water and hydration levels, mix components, temperature, humidity, aggregate components, and others. Dosage of particular rheology-modifying agent or combination of rheology-modifying agents is calculated based on a percentage of a nominal dose calculated with reference to a nominal dose response (“NDR”) curve or profile. The NDR profile is based on a correlation between a rheology value (e.g., slump, slump flow, yield stress) and the rheology-modifying agent(s) dose required to change rheology value by one unit (e.g., slump change from 2 to 3 inches) such that exemplary methods can employ corrective dosing based on the NDR and the measured deviation by the system.
