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.
Abstract:
ABSTRACT OF THE DISCLOSURE A system for adjusting a proper slump in a mixing drum of a mixing truck, the system includes a frame having an opening through which the mixing truck can pass; a camera mounted on the frame for viewing the mixing truck; a monitor for monitoring the camera, wherein the monitor is at a location remote from the mixing truck; a water pipe mounted on the frame for depositing water into the mixing truck; and a control panel for controlling the depositing of water into the truck, the control panel being adjacent the monitor. Optionally, the system may include a plurality of nozzles mounted on the frame and arranged for washing an exterior of the mixing truck. The system can be controlled from the remote location.
Abstract:
Apparatus for spraying a building mixture comprising a nozzle holder (2), which holds a discharge nozzle (4), a mouthpiece main body (6), and a hose (18). A protection ring (10') is situated in a recess (7) and held in the recess (7) by a flange (21) of the nozzle (4) and an O-ring (22). The ring (10') has a number of holes (12') distributed around its circumference. The body (6) has multiple liquid inlets (16') distributed around its circumference and provided by high pressure liquid jet nozzles (24) inserted into respective bores in the body (6). The nozzles (24) are connected to a high pressure liquid supply system which allows a constant supply of liquid of the correct pressure. The nozzles (24) are fed with a liquid at a pressure which is sufficient to disrupt the dry components of the mixture and wet them thoroughly just before the mixture thereby produced is ejected from the nozzle (4).
Abstract:
The invention relates to a method for granulating slurry and/or powdered material. According to said method, the material to be granulated is mixed with hydratable or hydraulically bondable solid matter and water, said solid matter reacting exothermically with the water and acting as a binding agent in the mixture. The solid matter is left to completely or partially hydrate or bond and the mixture containing the completely or partially hydrated or bonded solid matter is formed into granules. The method is characterized in that the solid matter and optionally the powdered material to be granulated is wetted or humidified and the solid matter is subsequently and/or to a substantial degree simultaneously mixed with the material to be granulated. The invention also relates to a device for carrying out said method.
Abstract:
A system (10) for mixing cementatious material, liquid and aggregate to form concrete includes a cementatious material measuring device (12) which provides dry cementatious material to an enclosed screw conveyor assembly (14). The dry cementatious material is thoroughly mixed with a liquid (68) within the screw conveyor (14) to form a flowable slurry without producing external cement dust pollution. The slurry is output by the screw conveyor (14) into a final product mixing chamber (16) where the flowable slurry is mixed together with aggregate to form concrete. The screw conveyor assembly (14) has an in-line input (20) and output (22), and space-saving diverging/converging conveyor sections (28, 56) to facilitate the retrofitting of existing concrete mixing plants. The conveyor assembly (14) includes a cement metering function as well as a slurry mixing function. A selectively openable and closable bypass gate (90) permits the dry cementatious material to be sent directly to the final product mixing chamber (16) in the event of conveyor failure.

Abstract:
Mobile mixing devices, mobile mixing systems, and related methods are provided. A mobile mixing device can include a frame and a mixing drum securable to the frame. The mixing drum can include a body that forms an internal cavity and can have a forward end and a bottom end. The mixing drum can also include a mouth at the forward end of the body that provides access to the internal cavity of the mixing drum. The mobile mixing device can include a heater support arm having a heater secured to an end of the heater support arm that is distal from the mixing drum. The mixing drum can be used to process cement material when the heater support arm is in a stow-away position or asphalt when the heater support arm is in a heating position with the heater facing into the mouth of the mixing drum.
Abstract:
The temperature of concrete can be monitored by a temperature probe. Typically, large volumes of concrete such as are typically carried in mixer trucks or mixed in industrial concrete production drums have a relatively stable, or slowly varying temperature, given the high thermal capacity of concrete. A sudden change in temperature can thus be attributed to an external event. A sudden addition of even a relatively small amount of water for instance, which has an even higher thermal capacity, can produce a notable sudden change in temperature. Examples where the detection of the addition of water can be particularly useful in the production and/or transport of concrete are provided herein. Moreover, if the temperature of the added water is known, and the quantity of concrete is also known, the sudden difference in temperature can be correlated to a volume of added water.
