Abstract:
Systems and methods for the advanced batching of liquid colorant for dispensing into loads of wet concrete are described. A color station 100 makes the batches of liquid colorant in weigh chambers 400a and 400b at the direction of a central authority 502. The color station 100 includes numerous different liquid colorants that are combined to form a specific color of liquid colorant. The color station 100 is in contact with the central authority 502 and receives and transmits information and data to and from the central authority 502. Proximity detection 522 is used to initiate the processing of the batches of liquid colorant.
Abstract:
Continuous mixer/dispenser (100) of mortar for filling channels, trenches or excavations (5) comprising: at least one tank (101, 101a, 101b) for separately- containing solid materials such as binders and possible additives (L) and inerts (I); - a premixing chamber (110) of the solid materials; - a system of batching plants (102,103) of the solid materials from the at least one tank to the premixing chamber; - a premixing conveyor (105) of the solid materials; a mixing chamber (120) for preparing the mortar through mixing of the solid materials with water (W); - a tank (101c) of water (W) connected to the mixing chamber to feed it with water; - a pump (163) connected to said tank (101c) of water (W) to pressurise the water contained in the tank to the desired value; - an adjustment system or flowmeter (164), which allows the amount of water (W) to be entered into the mixing chamber (120) to be controlled; a dispensing system (140) of the mortar into the channel, trench or excavation to be filled, in turn fed by the mixing chamber (120).

Abstract:
A process for making construction material may include mixing predetermined portions of two or more components of cementitious materials without ingredients that would allow the mixture to cure, and separating the un-curable mixture of the two or more components into a plurality of pellets, each having substantially the predetermined portions of the two or more components. An extrusion system may include a transport line configured to transport the dry pellets in a gaseous transport stream.
Abstract:
Mischvorrichtung (1) und Verfahren zur Herstellung eines Faserbetons, aufweisend: - ein Gehäuse (2) mit einer Mischkammer (3), - eine Flüssigkeitszufuhr (4) zum Zuführen einer Flüssigkeit in die Mischkammer (3), - eine Zufuhr- und Einstreueinrichtung (5) zum Zuführen einer Feinkornmischung und zum Einstreuen der Feinkornmischung auf die Oberfläche der Flüssigkeit sowie zum Zuführen einer Grobkornmischung und zum Einstreuen der Grobkornmischung in eine Suspension aus der Feinkornmischung und der Flüssigkeit, - ein Mischwerkzeug (6) zum Vermischen der Feinkornkornmischung mit der Flüssigkeit und zum Vermischen der Grobkornmischung mit der Suspension, - eine Strömungsleiteinrichtung (7) zur Ausbildung zumindest einer Zirkulationsströmung (S1) der Flüssigkeit in der Mischkammer (3), wobei die Strömungsleiteinrichtung (7) ein Seitwärtsleitelement (8) für einen Seitwärtsabschnitt der Zirkulationsströmung (S1) zum Einstreuen der Feinkorn- bzw.

Abstract:
The present invention provides a fast response method and system wherein one or more comb-type polycarboxylate ether (PCE) polymers, having a cumulative adsorptivity coefficient in the range of 40%-75%, are employed as fluidizing admixtures dosed into concrete by and in automated slump monitoring and control systems which iteratively monitors and adjusts the slump of the concrete mix.
Abstract:
Provided is a mixing and adjusting method for foundry sand that uses a sand muller, having weight measuring means for measuring a weight of the foundry sand to be mixed, water content measuring means for measuring a water content of the foundry sand to be mixed, water pouring means for pouring water into the foundry sand, and CB value measuring means for measuring a CB value of the foundry sand during mixing. The method includes calculating a total supplied water amount till the measured CB value of the mixed sand becomes larger than the lower limit value of a target CB value range, determining the total supplied water amount as a necessary supplied water amount corresponding to the water content in the foundry sand that is to be mixed, and determining, from an additionally supplied water amount during the additional water pouring and the CB value of the mixed sand subjected to the additionally supplied water mixing, a ratio of a variation in the CB value corresponding to the additionally supplied water amount.

Abstract:
A capsule delivery system provides for the delivery and dispensing of fluid or semi-fluid admixtures into concrete mixes. The capsule is made of a plastic resin and contains a pre-measured dosage of admixture. Once the capsule containing the admixture enters a concrete mix and the concrete mix is agitated mechanically such as via a concrete ready-mix truck, the plastic resin delivery and dispensing capsule shatters and breaks down unnoticeable to the unaided eye, releasing the encapsulated admixture into the concrete mix.
