Investigation of the Strength Characteristics of Shotcrete as a Function of the Technological Parameters of the Application

[摘要] The technology shotcreting of vertical surfaces in construction with application of pneumoframework moulds is rather studied, however the technological modes of a shotcreting of horizontal surfaces of pneumoframework moulds demand justification. Experimental studies have determined rational parameters of the technological modes of a shotcreting. By the results of the experimental studies there has been determined the character of the influence of technological parameters on the structural formation of construction material. Various parameters of a torch of shotcrete are set. The main vibration characteristics of fabric of a flexible pneumatic mould are established. Graphic dependences of durability are defined shotcrete on compression from the key technological parameters of process of drawing shotcreting.
