IGM Mladost – Leskovac

Throughout history, "Keramička fabrika Rafajlović, Sokolović i Bejaž", later known as "MLADOST", has become a synonym for superior clay construction material. 🧱

Distinctive roof tiles with an embossed elephant sign and vivid red color were created, on the foundations of an old brick factory, with a symbolic chimney that dominates Leskovac. From traditional methods to modernization in 1974, our factory strived to preserve quality and expertise at every step. A period of stability and moderate development followed until we became a joint-stock company in 2003, driven by the desire for innovation.

With the last investment at the end of 2010 and the beginning of 2011, as well as with the reconstruction of the new factory in Stalać at the beginning of 2018, the investment cycle was crowned with the installation of key technologies that will enable a significant improvement in the quality, quantity and range of production, all with the aim of satisfying the needs of our customers.

The construction material industry IGM MLADOST unites five factories in central and southern Serbia into one recognizable name known, above all, for the quality of its products. The factory in Leskovac organizes the production of tiles, while the factories in Toplička Mala Plana, Vlasotince and Stalać produce blocks for masonry and mezzanine constructions. MLADOST bases its great reputation on over a hundred years of tradition. Namely, with the establishment of our first factory for the production of ceramic products in 1911, the foundations of the modern production of clay construction materials were laid. The tallest chimney in Leskovac is located in this factory and is a symbol of tradition and a testament to the skill, stability and beauty of architectural creation.

The Beginning of Our Success

The production of clay construction materials in the vicinity of Leskovac, Vlasotince and in the Toplica basin is as old as the presence of human communities in that area. The abundance of quality raw materials was used by the builders of the ancient empires, leaving monuments of their construction skills. At the transition between Antiquity and the Middle Ages, Carica town near Lebane, the oldest architectural monument in southern Serbia, was created. The tradition of brick production from the Byzantine era continued in the Middle Ages, in which many works of sacred architecture were created, primarily in the basin of Toplica.

The Beginning of Our Success​

From those ancient times until today, there have been changes in ownership and organization, but not changes in the skill of making clay products, which, like the recognizable red color, has proven to be more durable than many social systems and epochs. Our factories in Leskovac, Vlasotince, Toplička Malá Plana and Stalać were built in the most attractive locations and on the foundations of such a long and rich tradition in the production of ceramic products.

IGM MLADOST Leskovac

1911

1911 – with the foundation of the "Keramička fabrika Rafajlović, Sokolović and Bejaž", the foundations of the modern clay construction material industry were laid. The huge building of the so-called "old brick factory" with the highest chimney in Leskovac is still one of the symbols of the city. The tiles that were produced in Leskovac at the beginning of the last century, with an embossed elephant sign and its distinctive, intense red color, still adorn the roofs of Leskovac, Niš, Vranje, Skoplje and many nearby and distant cities.
Traditional methods of shaping clay were applied until 1974, when a new hall was built with devices and machines for the production of tiles and blocks, modern for that period of history. However, certain segments of production at that time were still based on manual work and the use of a large number of workers, without a detailed consideration of the possibility of increasing the quality and quantity of production.

DP Pobeda

1928 – with the resignation of one of the owners, Mihajlo Sokolović, the factory was given the new name "Keramička fabrika Rafajlović i Bejaž". After the Second World War, the factory grew into DP "Pobeda" - an industrial company of tiles and bricks, whose products would be known throughout the old Yugoslavia.

DP Mladost

1997 – the company was divided into several smaller ones, specialized in the production of certain types of construction materials. This is how D.P. "MLADOST" was created as a group of young, hardworking and motivated people, who want to return to their old markets and present themselves in new ones. The period that followed was marked by stability in business and moderate development, in accordance with the general circumstances in society. 2003 – with the privatization, the company MLADOST becomes a joint-stock company, and the management and employees receive a new incentive for further improvement and development. From that moment until 2008, they worked on constantly increasing the quality and capacity of production, and the company IGM MLADOST completely reoriented itself to the production of tiles. In the same period, the company used the time for employment and professional development of new personnel of basic production profiles: technology, mechanical engineering and electronics.

EXTRACT FROM A SCIENTIFIC PAPER

“ASSESSMENT OF THE QUALITY OF BRICK RAW MATERIALS FROM THE SOUTH OF SERBIA” Zagorka Radojević, Ph.D., Milica Arsenović, Ph.D., Miloš Vasić, Ph.D.

The paper presents the results of research into the quality of three brick raw materials from the south of Serbia: from the deposit near Leskovac, from the deposit near Vlasotince and the deposit near Mala Plana. The research included chemical, mineralogical, granulometric and ceramic-technological characteristics of representative samples from the mentioned deposits. The paper also provides an assessment of raw materials from the aspect of the quality of brick products, energy efficiency and ecological parameters.

INTRODUCTION

The basic raw materials for the production of brick products are clay, loess, clay, marl, etc. Geological research and testing of raw materials in Serbia are carried out in a unique way. These researches are carried out according to generally valid methods and regulations, which provide sufficient data on the quality and quantity of raw materials and on the basis of which the decision on exploitation is made. There is no building material that could replace brick products in terms of strength, porosity, insulating abilities, durability, fire safety, resistance to weathering and corrosion, stability of form and the possibility to achieve diversity in construction. In addition to the mentioned positive properties of this building material, the production and use of brick products is also driven by the increasingly urgent need to preserve the environment, and thus the preservation of living, working and health conditions for people. The south of Serbia has a developed production of various assortments of brick products. Modern highly automated technological lines were put into operation in the plants for the production of brick products: “MLADOST” doo – Leskovac, “MLADOST-RAD” doo – Vlasotince and “MLADOST-TMP” – Mala Plana. Their work is based on a high-quality local raw material base. The paper evaluates the raw materials from the aspect of product quality, energy efficiency and ecological parameters.

QUALITY OF BRICK PRODUCTS

Based on the results of the examination of brick raw materials from the south of Serbia, it can be concluded that modern production can produce: Brick products of a wide range (tiles, facade bricks and blocks, brick products for interior walls, ceiling elements, porous brick products, etc.)

Products with high aesthetic properties, intense red color,

Products without salt efflorescence and defects of the action of lime,

Products with high mechanical characteristics (compressive and flexural strength),

Products that provide good fire resistance and excellent thermal and acoustic properties of facilities.

 The color of baked brick products basically depends on the mineralogical composition of the raw material, temperature and baking conditions. Iron has a dominant influence on the color of brick products. Brick raw materials contain iron mainly in the form of minerals from the hydroxide group (goethite, limonite). During the firing process, iron hydroxide is transformed into hematite, which gives the ceramic body a red color.  From the test results, it can be concluded that the color of the baked products is intensely red.

A low content or absence of carbonates indicates the absence of harmful effects of lime on baked products.

The mechanical characteristics of baked products are high.

ENERGETIC EFFICIENCY

The results of testing the ceramic-technological characteristics of the samples indicate that the required firing temperature is relatively low, 830-9000 °C . The low firing temperature significantly lowers the specific energy consumption in the firing process and increases the energy efficiency of the process. For the sake of comparison, the most often required firing temperature for brick products in plants in Serbia is in the interval 950-10500 °C . The good plasticity of the examined samples enables the production of brick products with thinner walls, i.e. less mass, which reduces the consumption of raw materials and energy consumption per unit of normal format.

ECOLOGICAL ASPECT

Avoiding environmental pollution is placed before modern production processes. The production of brick products allows the use of waste materials. Tested raw materials can be mixed with waste materials while designing optimal mixtures for a certain type of product. Emission of gases in the firing process comes from fuel and raw materials. This is how HF, SO3, SO2, HCl, CO2 and others appear. This issue requires serious studies of the overall emission and the necessary measures.

However, based on the results of the examination of the chemical composition of raw materials from the south of Serbia, there are no conditions for a significant emission, because the content of components that emit harmful gases in the baking process is minimal or absent. Even the carbonate content in the raw material is low, so there is almost no CO2 emission coming from the raw material.

CONCLUSION

Brick raw materials from the south of Serbia represented by the tested samples represent a significant raw material base for the production of various product ranges, with high aesthetic and physical-mechanical characteristics. The properties of the raw materials enable energy-efficient production in modern plants. Raw materials can be considered high-quality from the point of view of increasingly strict environmental requirements.
