TO THE QUESTION OF CONCRETE QUALITY CONTROL

The article provides information on the results of assessing the quality of concrete internal wall panels. The requirements of various regulatory documents for the rules for accepting a batch of concrete are considered. The procedure of statistical sampling control on a quantitative basis is described. According to the statistical data of the factory laboratory of Open Joint Stock Company “ZhBK-1” (Penza) on the quality of grade 300 concrete in the manufacture of internal wall panels, the influence of the type of cement on the variability of concrete strength indicators is considered. The influence of the type of cement on the decision to accept a batch of concrete is established. Due to the higher value of the standard deviation of the quality indicators of Haldenberg cement in comparison with Sengileevsky cement, the acceptance of a batch of concrete depends on the level of product defectiveness. It is revealed that, depending on the number of samples during testing, the decision on batch acceptance, made in accordance with GOST 10180-2012 and GOST R ISO 12491-2011, may be different. It is proposed to amend GOST 10180-2012 in paragraph 4 regarding the number of samples for testing, taking into account the requirements of GOST R ISO 12491. This will contribute to a more objective decision on the acceptance of the batch. The effect of the type of cement on the reproducibility of the production process is shown.

Оценка уровня воздействия техногенных факторов при добыче и производстве гранитного щебня

Using the example of Open Joint Stock Company «Pavlovskgranit», located in the Voronezh region, the level of impact of technogenic factors (air pollution and noise) during the extraction and production of crushed granite was estimated. It was established that 61 pollutants enter the atmospheric air from 134 sources of pollution. The main contribution to the total volume of emissions (1881.0 tons/year) is made by inorganic dust with a SiO2 content of 70-20% - 73.4%, sulfur dioxide - 9.8%, carbon monoxide - 114.3 tons/year. Blasting operations in open pits during the extraction of crushed granite are the leading production process that makes a significant contribution to the volume of emissions. At the same time, the remoteness of industrial sites from the territory of residential development, the presence of a sanitary protection zone, allows us to speak about the admissibility of the impact of concentrations of pollutants in the air and the noise factor at the border of the territory of the nearest residential development.

Analysis of the work of the commodity distribution network of JSC “Mogotex” and choosing a strategy for interacting with intermediaries

With the development of market relations, most domestic enterprises have gained access to new markets, including external ones. The study and development of these markets requires not only time, but also significant financial, labor and organizational resources. Domestic manufacturer deals with a horizontal, geographically dispersed market, where a large number of consumers are present, and creating its own sales network to serve them requires disproportionately high costs in relation to the expected sales volume. Intermediaries, by providing relatively easy and inexpensive access to foreign markets, play an important role in the export of the enterprise’s products and are designed to ensure more efficient movement of goods from producer to consumer, while producers can focus their attention and effort on producing high-quality products that better meet the needs of consumers.An analysis of the distribution network of the open joint stock company “Mogotex” has been conducted in the article, the structure of finished production enterprises through joint ventures and through dealers have been analysed, the analysis of dynamics of sales through distribution network has been performed, the author`s methodology for evaluating the effectiveness of intermediaries, has been сreated, taking into account the opinions of experts from the Marketing Department of the company under study and the weight of the criteria selected for evaluation, based on the developed methodology, depending on the average amount of points collected, the company᾽s intermediaries have been grouped and strategies for interaction with various groups have been selected. For the key intermediaries of the enterprise, the development of a program for their stimulation and support has been proposed.
