DEVICE TO ESTIMATE EFFECT OF ATMOSPHERIC AND CHEMICAL EXPOSURE PROCESSES AT CONSTRUCTION MATERIALS

摘要

FIELD: construction.;SUBSTANCE: device to estimate effect of atmospheric and chemical exposure of construction materials comprises two joined cylindrical vessels with flanges for fixation, where an investigated sample is installed. Vessels are a single tight cassette made of a transparent material, at the same time the inlet and outlet holes of the cassette are narrowed and equipped with filters and flat plugs. The device is additionally equipped with an air-intake device.;EFFECT: increased speed of material testing and accuracy in estimation of quantity and quality of material particles released during destruction, simplified design.;2 cl, 1 dwg
