Influence of the Geometrical Values of Hollowness on the Physicotechnical Characteristics of the Concrete Vibropressed Wall Stones

In this research article advantages and disadvantages of hollow wall stones (SKTs) were considered, which now are widespread at frame and monolithic construction. Also results of laboratory researches are presented in the article. Definition technique of three physicomechanical characteristics is visually shown: thermal conductivity, sound eliminate, vapor permeability. Separate sambles and fragments of stone layings were made specially for carrying out experiment. Two types of wall stones were compared: with slot-hole and rectangular emptiness. Emptiness differ geometrical parameters therefore they substantially define physicomechanical characteristics.
