AbstractAbout AuthorsReferences
The complex organic-mineral polyfunctional aqua-bond “KOMPAS” developed by authors is presented. It is intended for reducing the moisture content of raw materials without the process of their pre-drying. The bond “KOMPAS” is a mixture of cellulose-containing powder and a mineral additive or an organic plasticizer depending on the index of clay plasticity. It is recommended to introduce the additive in the amount of 0.1–0.4% of the total charge mass. On the example of the experience of some brick factories, it is shown that the introduction of the bond “KOMPAS” facilitates more dense packing of particles in the molding composition, improvement in mechanical strength of semi-products and ready-made articles, as well as reducing the open porosity and water absorption. Compositions of the additive for plastic and high plastic clays, moderately plastic and lean clays have been patented.

AbstractAbout AuthorsReferences
The research results of the material, chemical and mineral compositions of waste coal from Korkino open-pit coal mine are provided, and the dependence of the percentage of organic component in coal argillites on the size of the rock is revealed. The technology of waste coal recycling is offered to produce coal fuel and raw material for the industry of ceramic materials. On the basis of pilot industrial tests it was shown that a pneumatic waste classification allows to extract the remains of coal from argillite and get a stable ceramic raw material for brick production. Such complex processing of waste coal provides not only a significant expansion of the raw material base for construction materials subsector and generation of additional energy, but will also help to solve environmental problems and improve the environmental situation in industrial regions.

AbstractAbout AuthorsReferences
Normative requirements (compression strength and bending strength, adhesion to the masonry) for plastering mortars for finishing of walls made of autoclaved aerated concrete in the EU countries Ukraine, Russia are contradictory and not always substantiated. The plaster mortar is to be considered as a coating connected with masonry through the contact zone. The design of compositions and properties of plaster mortars should be carried out with due regard for stresses occurring in the plastering coating because of its shrinkage and the difference of deformations with masonry as well as deformations of the wall structure and the coating itself. Components of the mix and their number should be selected with due regard for the processes taking place in the course of plaster coating hardening and destruction of the “masonry–plaster coating” system. The result of selecting the composition should ensure the reducing of stresses in the plaster coating and contact zone up to values lesser than the destructive stress.

AbstractAbout AuthorsReferences
Developers of normative documents, which regulate the use of autoclaved aerated concrete, faced the problem of the absence of experimental studies. As a result of this, documents contain a large number of elements and requirements which were executed with a large reserve according to the well-established practice of applying. The tests of structures conducted at SIBIT factory will make it possible to revise some of these «reserves» that under conditions of market competition will favor the improvement of competitive advantages of aerated concrete.

In 2013–2014, Laboratory of seismic stability of structures of the Research Center of Earthquake Resistance of Structures of TSNIISK named after V.A. Kucherenko (JSC Research Center of Construction) by the order of the National Association of Autoclaved Aerated Concrete Producers executed the work on “Experimental determination of normal and shear adhesion of mortars and adhesive compositions, laid by thin layers, to cellular concrete blocks of autoclaved hardening”. Masonry joints of up to 2 mm thickness formed by three types of cement mortars for the thin-layer masonry and a layer of polyurethane assembly adhesive have been studied in this work. Joints in the masonry made of cellular concrete of autoclaved hardening of 300–600 kg/m3 density and 1.7–7.3 MPa strength have also been studied. By results of studies, it is established that the masonry of the first category (with a tensile strength along the non-tied section 180 kPa) can be made of blocks of B1.5 strength).

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.

It is shown that at present, basic volume of autoclaved aerated concrete in Russia is produced with the use of the molding technology, and this proportion tends to slow increase. However, noted that characteristics of ready-made articles produced with using different technologies don’t have principal differences, clearly indicating the manufacturing technology (except for homogeneity of pores and after-autoclaved humidity). It is concluded that each technology has its own features which can be described as advantages and disadvantages separately, but the comprehensive comparison does not allow us to make a conclusion without any relation to the features of the resource base and technological traditions. At present, the dispute about the benefits of both technologies is essentially subjective in nature.

AbstractAbout AuthorsReferences
Dampening of building materials and structures causes the reduction of their lifetime and deterioration of hygienic and sanitary conditions in premises. The application of hydrophobisators is one of prospective trends to ensure the growth of quality indicators in the construction industry. The authors are analyzing the spheres of efficient utilizing of hydrophobisators in construction. These are hydrophobization of concrete and reinforced concrete structures, sand-lime and ceramic bricks. Nowadays, the hydrophobization of Portland cement, mortars for plastering, products made of mineral wool, wood, magnesia binders is very actual. Protection of cement bonded particle boards, which are widely utilized as a stay-in-place form in monolithic housing construction with hydrophobisators, makes it possible to significantly improve their operational properties. The authors have determined the high efficiency of hydrophobization application for products with gypsum binder – gypsum plasterboard, gypsum-fiber tongue-and-groove slabs, and absolutely new for Russia gypsum-chip plates.

AbstractAbout AuthorsReferences
Possibility and basis of technology of reinforcing of wooden bark by basalt for obtaining a filler for structural heat insulation are considered. As a filler, it is proposed to use the bark of Scots pine (Pinus silvestris L), obtained from the dump of the lumber factory, and basalt sifting – waste of mineral wool production. Optimal dimensional characteristics of raw materials were selected. True density, coefficient and time of swelling, optimal composition of test samples were defined. Conclusions regarding the influence of time of wooden bark dispersion on its porous structure were drawn. Data about surface, sizes and amount of pores in the dry milled bark before and after the process of reinforcing by nano-sized particles of basalt were obtained. Fundamentals of technology, quality control and effective ways of reinforcing the bark by nano-sized particles of basalt for subsequent using as the filler for structural heat insulation were developed.

AbstractAbout AuthorsReferences
Thermal and mycological problems arising in the course of operation of the first and socle floors of buildings are described. The efficiency of using the extruded foam polystyrene in enclosing structures with the purpose to solve problems described is analyzed. Numerical calculations of non-stationary humidity conditions of enclosing structures with the use of extruded foam polystyrene under climatic conditions of various cities of the Russian Federation have been done. Values of the operational humidity in the layer of extruded foam polystyrene for various variants of structures have been calculated. A comparison on the values of operational humidity for analogous structures with the mineral wool and molded foam polystyrene (foam plastic) is presented. The dependence of heat conductivity on the operational humidity is described. The influence of humidity conditions on the values of energy efficiency of heat insulating materials has been investigated. The issue of loss of biological stability of damp layers of heat insulation has been studied.

AbstractAbout AuthorsReferences
The impact of edges of «semicircular and thinned from the face side» (PLUK), «modified and thinned from the face side» (UK Pro), and «thinned from the face side» types on the strength of joints of gypsum building slabs at different variants of joints execution – with the use of two types of putty as well as without use and with the use of reinforcing tape in the course of filling – are considered. Methods and criterion of the assessment of joints strength of gypsum building slabs have been developed and substantiated. It is proposed to consider the «deflection at the time of formation of the first crack» parameter, the value of which should be not less than 1 mm for 350 mm of the slab as a main criterion of resistance of the filled butt joint of gypsum building slabs to crack formation. It is established that the use of gypsum building slabs with the PLUK edge makes it possible to obtain the joint with the highest strength, and the use of the reinforcing tape gives an increased reserve of strength to the butt joint.
