ARBOLITE CONCRETE WITH A COMPLEX OF ORGANO-MINERAL ADDITIVES AND FILLERS FOR VARIOUS PURPOSES

Abstract

arbolit concrete, complex modification, strength, water resistance.

This article addresses the issue of increasing the water resistance and strength of composite gypsum binders for concrete arbolite. The characteristics of the raw materials used are presented, research methods and techniques are described, the applied methods for mathematical experimental design are outlined, and the selection of experimental plans and variation factors is substantiated.

An analysis is conducted of the possibility of increasing the biostability of concrete arbolite using a composite gypsum binder by adding a nanoadditive of highly active pyrogenic microsilica modified with silver, copper, and zinc compounds. Samples of concrete arbolite manufactured without and with the nanoadditive are presented at various magnifications.

An optimal composition for environmentally friendly thermal insulation and thermal insulation-structural types of concrete arbolite with increased biostability, modified with the proposed multifunctional modifier, is recommended. An analysis of the study results allows us to conclude that the complex modification of the composite gypsum binder with micro-reinforcement, polymineral micro-pozzolanic filler additives and Sika superplasticizer in optimal proportions allows us to obtain a composite gypsum binder with a softening coefficient of 0.9. Volumetric hydrophobization provides an additional increase in compressive strength and water resistance.
