MODERN METHODS OF INCREASING THE FIRE RESISTANCE OF BUILDING MATERIALS

Аннотация

This research paper expresses opinions on the further deepening of economic reforms and the rapid development of a network in the building materials industry, special attention is paid to the production of new modern building materials, structures and products, modern methods for improving the fire resistance of building materials. Limiting the use of combustible materials reduces the likelihood of fire safety impact on people; from the practice of numerous experiments, it is known that hardly combustible and even non-combustible materials decompose under fire conditions with the release of smoke and toxic products. As the fire intensifies, the combustion of these materials intensifies, the flame spreads over the surface and generates additional heat, that is, the material acquires the properties of "non-combustible" and "slow-burning", and the disadvantages of the traditional standardization system must be justified from an economic or technological point of view. KEYWORDS: Building materials, products, industry, cement, asbestos-cement slate, asbestos- cement pipes, wall materials (brick), lime, gypsum, window glass, soft covering materials, natural stone. “MODERN METHODS OF INCREASING THE FIRE RESISTANCE OF BUILDING MATERIALS” P age 37 | 6 INTRODUCTION being consistently implemented in all spheres of our country's life, I think, do not leave a At present, in the building materials industry, single citizen unattended. Today, our country special attention is paid to deepening is implementing comprehensive measures economic reforms and the rapid development aimed at building a legal democratic state, a of the network, the production of new modern strong civil society, developing an economy building materials, structures and products. based on free market relations and the priority Expansion of the types of manufactured of private property, and creating conditions building materials, an increase in the share of for a peaceful and prosperous life of the production of modern, convenient and high- people. and take a worthy place of Uzbekistan quality products based on a localization in the international arena. program and, in turn, a decrease in the share of imports, further development of the The use of production waste and secondary industry, and improving the quality of training resources in the production of building specialists in this direction is one of the main materials and products allows us to solve the issues of our time [1-3]. following urgent problems. It is known that the building materials industry • solves the issues of ecological cleanliness, is an industry that produces building materials ecological system, reduces land use; for the construction sectors of housing, • saves energy sources and dramatically industry, agriculture, etc. This field includes reduces consumption costs. several sectors. Including cement, asbestos- The process of using industrial and agricultural cement slate, asbestos-cement pipes, wall secondary resources in the production of materials (brick), lime, gypsum, window glass, building materials leads to the saving of a large soft facing materials, natural stone facing amount of energy and stocks of raw materials. materials, ceramic (ceramic) tiles for It is necessary to fulfill environmental, decoration and floors, heating radiators and economic and technical requirements for the convectors, porcelain - faience sanitary use of secondary resources. For this reason, construction products, linoleum, the issues of classification according to their prefabricated reinforced concrete structures composition, degree of extraction, and and parts, non-ferrous building materials ecological cleanliness are considered relevant. (crushed stone, crushed stone, sand, gravel, sand and gravel mixture) are the main Outside, it is affected by solar radiation, products of the building materials industry. precipitation, changes in temperature and humidity, noise, and from the inside - heat Currently, the demand for energy-efficient, flows, water vapor, noise. Therefore, when cost-effective materials and products is creating a building project, it is necessary to increasing in the construction industry around pay great attention to the choice of the the world. At the same time, building materials location of the walls, their design scheme and made from agricultural waste, firstly, save type. In addition, it must be durable, stable, energy in the process of their production, and spatially homogeneous, correspond to the secondly, due to the use of agricultural waste, level of fire resistance corresponding to the its cost is also partially reduced. At the same class of the building, provide a certain time, the use of secondary breeds for the temperature and humidity conditions in the rational use of depleted resources is a topical room, provide sufficient sound insulation, be issue today. Comprehensive reforms that are “MODERN METHODS OF INCREASING THE FIRE RESISTANCE OF BUILDING MATERIALS” P age
