AbstractAbout AuthorsReferences
New aerated concrete plants use a unilateral tilting of the array in cutting process which improves the production quality and increases the coefficient of utilization of the autoclave. A drawback of the unilateral canting is a formation of a facing layer. The use of the crushed facing layer as hydro-silicates, crystallization centers, is efficient, but it is connected with the increase in water demand of the mix. The work presents the research in the use of the facing layer pre-treated with a hydrophobizator. The study of the influence of water repellents on the lime slaking is also presented; a minimal impact on the lime slaking temperature has been defined. The study determined the composition of a complex additive containing the crushed facing layer and water repellent. The use of the additive treated with the hydrophobizator maintains the fluidity of the mix and leads to improving the strength.
