For the placement of concrete or mortar into the joints used pneumatic blowers, mortar, screw pumps and vibrobunkery. Pneumatic blowers operate the compressor with pressure 8.6 atm. They create a network steady motion solution that facilitates the conditions of his perekachivaemosti. In the constructive attitude supercharger is easier and more durable mortar it in operation, as it has no rubbing parts. In foreign practice there rastvorotransportnye installation with single screw pumps continuous action. The pump is capable of creating significant pressure, which allows to deliver a mixture of both horizontally and vertically. In our the country has been applied mortar construction tsniiomtp system ns Marchukova. BSA has firm opinions on the matter. As well as in pneumatic blowers, ready-mixed concrete is transported by pipelines.

A mixture of moves in suspension state in a jet of compressed air (from the compressor) and exits from a nozzle at high speed than a similar action torkretnoy installation. This mortar has been used successfully for seams in shells cover the two markets in Moscow. Installation and zamonolichivanie from small-scale mechanization should be noted vibrobunkery. The main elements of vibrobunkerov used for sealing horizontal joints: a bunker containing a mixture, vibrator, inducing output mixture from the hopper, and , sealing the concrete in the joint. Installation and zamonolichivanie spatial structure is necessary to conduct year-round, including at low temperatures. Period of negative temperatures in the northern regions of our country often exceeds 6 months, and frost reaches 40h-50 C. Under these conditions of utmost importance that the correct issues shells.
