Clinker Brick: Standardization, Properties, Application

The article discusses the issues of standardization of the properties of wedge-core products: road and wall bricks. The main provisions of the state standards in terms of technical characteristics of clinker bricks are reflected and gaps are indicated in terms of the use of clinker bricks in construction rules. A European approach to standardizing the properties of products for masonry was noted as a parameter of average density and establishing dependencies of technical characteristics and property groups. The classifications of ceramic products in related industries are given through the parameter of water drainage: sanitary products and ceramic tiles (thin ceramics). The market analysis data for masonry products for clinker products, the composition of which depends on the purpose and type of products, its water absorption and the masonry method, are shown. It is proposed to introduce the term “clinker ceramics” for sintered ceramic stone with water absorption of less than 6%. Clinker ceramics are divided into 3 groups: with a low water absorption of less than 0.5%; with average water absorption of less than 0.5–3%; with high uptake of less than 3–6%. Products based on clinker ceramic can have different shapes, sizes and emptiness and be made in the form of brick, stone, block, tiles, etc. It was noted that for the successful development and introduction of clinker products into mass construction, it is necessary to accumulate and analyze data on the properties of clinker products, as well as structures based on them, and reflect the obtained data in the regulatory and technical framework.
