For reduction of a consumption of cement or to reduce property of moisture absorption, it is necessary to select the necessary structure from concrete and softener.
Softener is added to concrete mix in the form of water solution of the necessary concentration. It is desirable to prepare softener for concrete mix at ambient temperature above zero, dissolving it in the cleared and washed out capacity protected from hit of all rainfall. Solution prepares by hashing before receiving a uniform consistence.
At production of paving slabs different dyes as the color paving slabs have more elegant appearance, unlike a tile from unpainted concrete are widely applied. For production of paving slabs softeners and pigments for sidewalk plitkirazny shades are used. Inorganic pigments of powder type for production of a tile of a different coloring before application have to mix up carefully with water before receiving by consistence sour cream. At once it is impossible to add to concrete dye - it is necessary to stand him at least one hour. The endurance increases dispersion of dye and improves the painting properties.
Conditionally all pigments are divided into 2 big categories - the natural and synthetic painting pigments. Natural are oxides of iron of yellow or red color, a manganese oxide, etc. Certainly, natural pigments differ on color, but the high-quality dyes made on their basis have no considerable deviations in a shade, and conform to standards. Pigments for coloring of a synthetic origin are made of salts of iron, side effects, generally black, brown and yellow flowers.
