Study of the Degree of Homogeneity of Foam Concrete Produced by Two-stage Introduction of Foam

Abstract

The article presents a method of foam concrete production, which involves a two-stage introduction of foam (DWP). The proposed method involves improving the pore structure of foam concrete, due to a more uniform distribution of pores throughout the volume of the material. A comparison of the qualitative indicators of the obtained material was carried out in relation to the samples made by the classical method (CM) and dry foam mineralization (SM). Laboratory tests were carried out for three types of samples, represented by point determination of strength characteristics of small samples throughout the volume of foam concrete block. Block dimensions are: height – 20 cm, width – 30 cm, length – 60 cm. The obtained results of tests of small cube-shaped specimens gave us an indirect idea of the degree of homogeneity of the materials of the three compared production methods. The obtained results of the comparisons, showed that the fiberboard samples have a more uniform distribution of the pore structure of foam concrete relative to the samples of KM and SM.
