Dry Construction Mixes

Dry mixes for today were widely in construction. You will confirm any, whether the builder – a beginner or an experienced professional that mixes become material for floors, an integral component repair and waterproofing compounds, adhesives for stone and ceramics, the pointing Grout color, grout for joints of granite – all these mixes, which are distinguished by high consumer qualities. Dry mixture – this is, by and large, cement and sand, but over time in the manufacture of mortars have been used these or other additives (for example, increasing the reliability of the final layer, water-retaining) to give required properties (setting time, strength, toughness, etc.), but it is worth mentioning that the qualitative results will differ from those obtained with the use of standard cement-sand mixtures. In plaster case mixes are also very much needed: they are formed by surface texture, plus their application can adjust the viscosity, setting time. Straining cement – a variant of the expanding cement representing a fast setting and quick-binder.

Solidified solution has a high water resistance. Straining cement is useful for thin-walled concrete design and construction of capacitive structures, manufacture of pressure pipes. Alumina cement – a hydraulic binder material obtained by roasting, which is produced in blast furnaces, electric commodity a mixture of bauxite and limestone, and characterized by high speed. Alumina cement on the content of Al2O3 is divided into ordinary alumina cement (the contents of Al2O3 and 55% of its melting temperature will be 1450-1480 C) and high-alumina cement (up 70%; 1700-1750 C). Good high alumina cement refractory, a rapid strengthening of ties, resistance to corrosion. The refractory mixture – is a dry mixture on the basis of high-alumina cement and refractory fillers in the composition is still a mixture of modifying additives; refractory mixture is used in masonry and plaster furnace repair heating units. To date, dry mixes in the stores are as both foreign and domestic producers (Ceresit, Glims, etc.).
