Peat-vermiculite compositions for granulated material production

Abstract
The paper presents the research results of peat-vermiculite compositions for the production of granulated material with heat-insulating properties, that can be used in the construction of low-rise buildings. The paper considers the possibility of producing a heat-insulating granulated material based on a peat-vermiculite mixture. The obtained data on various methods of the peat-vermiculite mixture granulation are analyzed. It is found that the optimum concentration of the Akvasil water-repelling is 10% in the mixing water. This concentration allows reducing the water absorption of peat-vermiculite compositions by 16% and increasing the material strength by 20%. Further increase in the Akvasil concentration in the mixing water does not lead to a significant change in the water absorption, and the strength properties decrease.
