Abstract
At construction industry enterprises, in particular at plants manufacturing coloured calcium silicate bricks, aerosols and fine dusts of raw materials are formed in the course of various processes of grinding, transporting, mixing, pouring etc. They are characterized by a high degree of dispersion and high concentration in working zone air and exceed the Maximum Permissible Concentrations by several times. One of the most significant reasons for increased dust amount in the air of working zones of industrial shops is the presence of locations of dust wastes storage. For the purpose of complete evaluation of dust conditions inside an industrial shop for components mixing for coloured calcium silicate bricks, it is necessary to investigate the dispersion process and the aerodynamic properties of the finest dust – colour pigment. The authors have conducted experimental investigations of the aerodynamic properties of colour pigment for calcium silicate bricks and formulated the conclusions.
