Conclusion

According to the State Program of Industrial and Innovative Development of Kazakhstan for 2015-2019 (SPIID), the production of construction materials remains one of the priority sectors of the manufacturing industry, the main market trend for the period 2015-2017.

The construction materials market has great potential for further development. The availability of a sufficient raw material base has all the prerequisites for increasing the growth of production capacities of Kazakhstani enterprises in order to cover the basic needs of the domestic market and reduce import dependence.

One of the most popular building materials in Kazakhstan is rubble. It is well known that the crushed stone industry in the territory of the Republic of Kazakhstan is experiencing a huge upsurge today. In Kazakhstan, markets for non-metallic construction materials, including sand and crushed stone, are represented by domestic producers in almost all regions of Kazakhstan and have a local (regional) distribution character.

Crushed stone production in the regions is developed in Akmola, Almaty, Aktobe, Kyzylorda, Zhambyl, South Kazakhstan and Karaganda regions. Further plans for the construction of new structures and roads indicate that the peak in the production of crushed stone has not yet been reached and the need for crushed stone today can exceed existing ones.

Improving the quality of crushed stone, as well as building materials, is one of the main problems. Its solution at the enterprises of the industry is possible only on the basis of the introduction of the latest technologies, equipment and modern methods of organization of production and management. A key issue in this area is the quality management system. Enterprises should develop and implement innovative programs to implement and support quality systems at the proper level.
