Features of Production of Structural and Heat-Insulating Masonry Mixes

Abstract: The article suggests compositions of structural heat-insulating masonry mixtures with the use of hollow glass microspheres. To extend the range of compositions and the field of use of these mixtures were considered various masonry materials and dense cellular structure on the basis of cement and lime-sand binder: gas-silicate, foam and expanded-clay concrete gravel. It is shown that by varying the ratio of the microspheres and the water-retaining agents we can enhance the degree of uniformity of wall construction by heat-insulation and strain characteristics when using masonry products with a density range of 500-1300 kg/m.3 Key words: Masonry mortars Microspheres Water retention agent Heat-insulation propertie INTRODUCTION the most homogeneous masonry construction in terms of The construction of wall structures possessing high In this regard, it is very actual to develop strength and insulating properties, is an important aspect constractional heat-insulating masonry mixtures in the construction of modern buildings and (CHIMM) with tailored properties by varying the number constructions. of hollow glass microspheres and dosing a stabilizin
