Title of the articleExpanded clay aggregate foamed concrete of the dry mixture for the foamed concrete
Abstract.Claydite as wall material, has advantages in strength and durability, but for more effective use needs to improve its thermal performance. On this basis, the technology expanded clay aggregate foamed concrete of obtaining of dry mixes, and worked through the technology of receipt. In the first phase of work were studied: the kinetics of water absorption of expanded clay gravel, depending on its density, as well as the ways and modes of obtaining technology expanded clay aggregate foamed concrete. It is established that the main water absorption, for all densities are within the first 5–10 minutes. This is reflected in the selection of compositions and modes of obtaining expanded clay aggregate foamed concrete. Тhermal performance of the material depends on its density, therefore, were studied as a function of density and strength expanded clay aggregate foamed concrete mixture occasionally stirring it. Мinimum density is reached at 4-5 min of mixing. Maximum strength is obtained after 3 min. mixing, but because loss of strength with respect to 4 minutes is insignificant, in order to achieve lower density taken 4 min of mixing.
Keywords.Expanded clay aggregate, non-autoclave foamed concrete, expanded clay aggregate foamed concrete.
