Guzenko S. The small-sized equipment for work on concrete mixtures оn the construction site.

It is proposed a set of small-size equipment for work on large concrete mixtures in the construction site and of syringe - concrete works on the concrete mixtures of various mobility, including, inactive the novelty of the design of this kit is to under delete the current set of pneumatic installation of ejection type, the way of building mixtures confirmed by patents of Ukraine. Theoretical investigation of the processes, occurring during the transportation of coarse-grained concrete mixtures and holding the syringe - concrete work. The dependence for determining the range transportation of coarse-grained concrete mixtures. The results of experimental studies of the process of transporting grained concrete mixtures preparation and holding the syringe - concrete works. On the basis of the constructed models, there was defined area of rational parameters of work of the equipment on the coarse-grained concrete mixtures when using pneumatic mouth-operation ejection type. There was developed the methodology of calculation of small equipment when working on coarse-grained concrete mixtures, and technical documentation for the manufacture of pneumatic installation. The results of the thesis were introduced during the repair works of the 1-t terminal of International Kharkiv airport.
