MATHEMATICAL MODELING OF THE OPTIMUM MODES OF CONCRETING WITH THE USE OF PNEUMATIC FORMWORK

Problem statement. The construction of a sufficient theoretical model of pneumatic formwork work and description of the dependence of strength properties of the concrete obtained on various parameters of the process of shotcreting are the problem of great importance. Results and conclusions. Experimental-theoretical model of the technological process of fine-grained concrete mix shotcreting on horizontally located pneumatic formwork is presented. Recoil indicator and concrete strength dependence on such parameters, as the productive capacity of shotcrete-machine, the nozzle diameter, the distance from the nozzle to the formwork surface and tension of pneumatic formwork material. The comparison of theoretical dependences and experimental ones has shown their qualitative correspondence.
