“…Aluminium holds a leading position in the global production market; the aluminium industry is one of the most dynamically developing branches of smelting industry [1]. This is because the produced aluminium, thanks to its unique properties (low density, high electrical conductivity and corrosion resistance), finds increasingly widespread use, including in the form of powders and fine powders [2][3][4][5][6][7][8][9][10][11][12], even in industries where it was practically absent before. For example, for a long time it has been known that aluminium in the production of aerated concrete -a material that is highly popular in the construction materials market due to its good thermal insulation and fire resistance [13,14].…”

Today, the development of aluminium industry is highly dynamic. Aluminium production rightly takes top positions in the global metal market. Unique properties of aluminium mean that it is widely used in various industries. The construction industry is no exception – here, aluminium is actively used as a gassing agent for production of steam-cured aerated concrete, which is produced by mixing Portland cement, sand, water and aluminium fine powder or aluminium paste. The main disadvantage of aluminium fine powder is its high degree of dusting: at certain air concentration levels, this becomes fire-and explosion-prone. This is the reason the producers add complex organic additives into their aluminium fine powder: to ensure lower dusting levels and produce an aluminium paste, which is safer to use. This work focuses on obtaining an aluminium paste with sufficient share of organic additives to ensure the efficient performance of aluminium paste as a gassing agent in the production of steam-cured aerated concrete. A number of tests were carried out on mixing aluminium fine powder with various organic additives (fatty additive; wetting agent and gassing kinetics stabiliser; dedusting agent) in different ratios. The paper analyses the quality of distribution of organic additives inside the finished product and studies the relevant gassing kinetics.

Method for determining parameters of the burning rate law including combustion of high energy material samples in a manometric bomb is proposed. This method is based on solving the inverse problem of internal ballistics in an integral formulation. Unlike the prior versions embodiments of the experimental setup, the principle of ignition of a HEM sample by a heated spiral is used herein. In the prior versions, the ignition of the sample was carried out with black powder, which introduced errors due to gas formation during the burning of the powder. In addition, heat-insulated inserts are installed on inner walls of manometric bomb to prevent heat losses. The results of the method verification for model high energy material are discussed. Verification of the proposed method for identifying the parameters of the burning rate law was carried out for the model HEM composition with known values of thermophysical and ballistic characteristics. The integral method allows determining parameters of the burning rate law u 1, v with the error of not more than 3-4% by experimental dependence p(t) measured with a random error of 10%. At the same time errors of determination u 1, v by the differential method is 14-32%.
