Slip resistance on dry and wet surfaces
The degree of surface sliding is determined by the kinetic and dynamic conditions of motion of the body interacting with the surface.
An article is textual and illustrative material in which the author sets the task of analyzing social situations, processes, phenomena, primarily from the point of view of the patterns underlying them.

The word "brick" is borrowed from Turkic languages. Before brick, Rus' used a “plinth” - a thin and wide clay plate measuring about 40 x 40 cm, with a thickness of 2.5 to 4 cm. Such a plinth, for example, was used in the construction of the St. Sophia Cathedral in Kyiv. The shape and size of the plinth are explained by the ease of molding, drying and firing “thin” bricks. It was made in special wooden forms, dried for 10-14 days, and then fired in a kiln.
The other day I was able to attend a seminar conducted by the commercial director of the Maska plant in Novosibirsk for wholesale buyers of dry building mixtures. Having recorded his speech by milestones, I approached him with a proposal to post the most interesting information on the site.
Ceramic tile is a blocky, repeating element of a wall or floor surface. The quality and value of the cladding directly depend on the symmetry and uniformity of its individual components, i.e. individual tiles in relation to the quality of the surface and its dimensions.
The reasons for the appearance may be the following factors:
- excess moisture in the base;
- uneven distribution of the adhesive composition;
- presence of dust, dirt, grease stains...
Some ceramic glazes contain lead and other hazardous elements. The authors suggest replacing them with less harmful analogues. The article describes various types of lead-free glazes, their compositions, properties and manufacturing methods. Particular attention is paid to decorative effects.

Glaze is a shiny or enamel glassy layer in the form of a thin film (0.1 - 0.3 mm). The chemical composition of the glaze and the ceramic shard is different. Their thermal expansion also varies in size. For strong adhesion of the glaze layer to the shard, one must strive to ensure that the thermal expansion of the glaze and the shard is equal.
Linear thermal expansion is expressed by the dimensional changes of any material due to changes in temperature. Moisture expansion refers to the expansion of the tile due to the absorption of moisture.
Frost resistance is the ability of ceramic tiles to withstand freezing in a humid environment and at temperatures below 0 degrees Celsius. The freezing mechanism is divided into two stages.
