AbstractAbout AuthorsReferences
Issues of the utilization of mineral wool heat insulating material after the completion of the life cycle are considered. It is shown that one of the prospective ways of secondary use of mineral wool can be its use as an additive when preparing the batch for manufacturing foam glass materials. Technological operations of utilization are substantiated. Proposals about the boundaries of using the proposed method and the spheres of application of the material obtained are made.

AbstractAbout AuthorsReferences
A possibility to produce geo-polymer binders on the basis of fly ash of the Apatity TPS has been studies and proved. Main criteria of the efficiency of its use as an active component for producing alkali-activated binders are identified. Among them, the content of free CaO is less than 5% and a high concentration of the X-ray amorphous component (a glass phase) in the composition of ash-slag mixture – over 60%. It is established that the mechanical activation positively effects on the reaction activity of the fly ash when it is alkali activated by two types of alkali activators studied, in this case the most efficient agent for the fly ash of the Apatity TPS is NaOH.

AbstractAbout AuthorsReferences
Criteria of using water-dispersion synthetic polymers for interior finish of pre-plastered or pre-puttied premises are determined. Acrylic and styrene-acrylic dispersions, due to containing ion carboxylic groups, are exposed to the alkaline impact that requires their study in the course of their interaction with high-alkaline cement systems. To analyze the degrees of influence of an alkaline agent, rheological peculiarities of dispersions have been determined with increasing the PH level. It is revealed that acrylic dispersions have higher viscosity at high shear rates; styrene-acrylic dispersions are the least susceptible to the impact of calcium hydroxide, have low viscosity at an equal concentration and size of polymer particles. These properties are used for producing efficient water priming compositions of deep penetration on the basis of styrene-acrylic dispersions, and, on the basis of acrylic dispersions, for producing paints with a high content of pigments.

AbstractAbout AuthorsReferences
It is established that the use of a complex additive consisting of a plasticizer and a fine mineral component (OMD) makes it possible to obtain high-strength self-compacting concrete. It is found that the partial substitution of micro-silica for the equivalent rate of a fine filler, zeolite in particular, reduces deformations of autogenous shrinkage without reducing the strength characteristics of concrete.

AbstractAbout AuthorsReferences
Four different types of wall structures with the same heat transfer coefficient are considered. Values of the СО2 emission during the process of their manufacturing are presented. It is shown that in the course of manufacture of 1.0 m2 of wall structures the significant emission of CO2 per 1.0 m2 of wall surface takes place. In the course of production of timber wall structures, the amount of tied carbon emitted during the manufacturing is lesser than the amount of carbon contained in materials which the wall is made of. The conclusion about ecological friendliness and energy efficiency of frame and timber buildings is made. It is shown that in the course of timber structures manufacturing the least amount of СО2 is emitted comparing with the variants considered.

AbstractAbout AuthorsReferences
Methods for the study of strength characteristics of building rocks are considered. The differences of methodic approaches to the evaluation of rock strength in domestic and foreign practice are revealed. It is noted that the domestic practice of design of crushing-and-sorting complexes assesses the strength of rocks according to the value of ultimate compressive strength. Abroad, the criterion of rock strength is a resistance to impact loads – the standardized method of drop weight (DWT), which makes it possible to determine the specific energy of destruction and impact strength of a material on the basis of which the simulation of crushing technology and selection of crushing equipment are executed. The need for comparing results of strength properties tests of rocks which are conducted with the use of different methods and assessed according to different values is indicated. Results of the strength study, using different methods, of gabbro-diabase of one of industrially developed deposits of Karelia are presented. The comparative assessment of results obtained with the use of different methods is made. On the basis of experiments, significant fluctuations in the obtained values both of the specific energy of destruction and ultimate compressive strength are revealed. The need to test a significant number of samples to obtain statistically significant and reliable results is indicated. The identification of heterogeneity in the strength properties of rocks is of great importance for operative control over the process of disintegration. It is substantiated that the solution of this problem requires the development and standardization of techniques for operative determination of strength of rocks in factory laboratories.

AbstractAbout AuthorsReferences
The quantitative analysis of the influence of the professional level of staff potential of enterprise manufacturing building materials on the quality of manufactured products has been made. In the course of the study, main components of workers professionalism have been determined and appropriate scales for their transition into quantitative form have been established. With the help of geometric averaging, a generalized criterion of professionalism, which can be considered as a controlled independent variable, has been formed. On the basis of accumulated empiric data, the mathematical model of the influence of workers professionalism, evaluated according to the proposed criterion, on the expected level of products defectiveness has been obtained. The use of this mathematical model will allow the employees of staff services of enterprises to plan and correct the personnel structure of employees of the main production of building products on the basis of the criterion “professionalism” relying on established target indicators in the field of the quality of ready-made products.

AbstractAbout AuthorsReferences
The change in the kinetics of hydration of a silicate binding mix containing the belite phase of slag at the initial stages of hardening with the use of micro-calorimetry method has been studied. The low hydraulic activity of the belite phase of slag under the natural conditions of hydration has been established. The level and conditions of the preliminary lime slaking significantly influence on the velocity and intensity of the hydration reaction of a lime-slag binder. The reasonability of increasing the reaction activity of a raw mix of the binder due to the preliminary sulfate activation of lime with possible acceleration of processes of the hydration of slag belite phase is shown. In the complex, the use of the proposed methods will make it possible to replace the cement in the composition of the raw mix of gas concretes by steel-smelting slag, to regulate the processes of hydration of the binder for combining the structure formation and gas release of cellular concrete mix when developing highly efficient construction materials.

AbstractAbout AuthorsReferences
The development of materials of a new generation on the basis of a complexly activated silicate mix, which combine a number of unique properties and are manufactured by the cast technology, is presented. The transition from the autoclave treatment to curing with energy saving regimes is provided due to the realization of complex activation of the silicate-concrete mix that is one of the technological features of producing this kind of material. Advantages and prospects of the manufacture of silicate products of a new generation of non-autoclave hardening with the use of energy saving and environmentally friendly technologies and available technological methods are substantiated. Possibilities of the computerization of production processes on the basis of software creation from the blocks of experimental-statistic models and developed methods for the mobile and qualitative selection of compositions with a high degree of reliability of results are shown.

AbstractAbout AuthorsReferences
An issue of improving the vibro- and earthquake resistance of brick masonries with the use of nano-technologies is considered. It is proposed to use methods which don’t require significant capital expenditures. The efficiency of using self-compacting cement mixes obtained with the help of superplasticizers – polycarboxylates, molecules of which are nano-particles, is shown. The use of the sol-gel method when preparing brickwork mortars, modification of cement polyvinyl acetate mortars with esters of orthosilicic acid is very effective. A method for protection of silicate brick against destruction during the fire with the help of intumescent paints, which contain fullerene-like nano-particles – fulleroids, is proposed. Introduction of basalt microfiber in the form of fibers with a nano-modifier fixed on them in cement mixes efficiently affects the strength of masonry mortar.

AbstractAbout AuthorsReferences
Data on the method for pressing (bed of brick, stretcher) of silicate brick at Russian silicate brick factories are presented. Raw strength is one of the indicators of press equipment operation and quality of molding sand composition. Press equipment of foreign producers requires strict compliance with a particular quality of the molding sand and raw components. General recommendation on selecting the press equipment and dependence on the coarseness of sand are made. Methods for the determination of strength at adobe brick compression (raw strength) are considered. It is shown that the methods of testing of adobe brick molded as bed of brick and as stretcher should be different. Studies of the influence of the method for adobe brick molding on the value of raw strength and the testing methodology are presented.
