The invention relates to a mixing and conveying device for mixing and subsequently conveying semifluid materials, in particular mortar and concrete. The device comprises a compressor for generating compressed air, and a mixing vessel connected to a conveying conduit and an agitator gear. The mixing vessel is charged with the material to be mixed and conveyed, and compressed air is admitted into the mixing vessel for discharging the semifluid materials through the conveying conduit. The agitator gear is driven by at least one compressed air motor that is supplied with a proportion of the compressed air generated by the compressor.

Rotor gun means for the air placement of granular and cementitious material. A mixing chamber for granular and cementitious materials, has a rotor gun mounted therein. The rotor gun comprises a motor driven wheel having a plurality of holes or apertures equally spaced about said rotor wheel. The apertures pick up the material and pass in front of a source of high pressure air stream which blows the material from the apertures.

The invention relates to methods and apparatus for a vibration-free placement of the concrete and for placement and enforced speed inertial compaction of the concrete under a high pressure. The method permits to optimize the values of the compaction factor of the concrete mix being placed without vibration. Whereupon, in the case of variation assigning and implementing (adjusting and optimizing) the integral indices of the mix, and/or the plume modes, and/or the space medium characteristics, increasing the concrete strength in early time of the concrete curing, increasing the width of the placed and compacted mix in one step of concreting, reducing the mix losses in the case of placing with compacting the concrete mix. The method implements a stage of concreting under super-high pressure using a speed force inertial characteristic of components, wherein the steps are joined into the continuous serial process of the steps of: preparing the mix, unloading and transporting thereof, reconstructing the stream, discharging the mix stream for placing with compacting thereof, particularly by means of stabilizing the uniformity of the concrete mix. The apparatus is designed for implementing the method.

A mixer mount for mounting a mixer to a sprayer cart includes a mixer clamp, a mixer bracket mount, a mixer bracket pivot and a support assembly. The mixer clamp is connected to the mixer bracket mount. The mixer bracket mount is connected to a mixer bracket pivot at a pivot point. The mixer bracket pivot slidably engages in the support assembly so that the distance between the mixer clamp and the support assembly may be changed. The support assembly is capable of connecting to a sprayer cart.

Mixing apparatus includes a batch mixing vessel with an inlet to receive constituent material, an agitation assembly for mixing the constituents and an outlet to convey batches of the mixed is provided. The apparatus includes a pressurizing device for pressurizing the vessel to assist in evacuation of the mix, and a conduit through which the mix is conveyed. A single pneumatic source is used both to pressurize the mixing vessel and to drive a jet pump including the batch loader. During the mixing cycle, the compressor used to discharge the finished mix is generally idle. This compressor can be used during these periods to drive a jet pump to load the mixing vessel. Therefore, manual loading is avoided and can be achieved such that the mixing cycle time is not interrupted.
