About dry construction mix

A dry mix is ​​a product in which dry binders, fillers, and special polymer additives are mixed in appropriate proportions. Portland cement, air lime, construction gypsum and polymer powders are used as the binders. Limestone powder (flour), powdered cretaceous, and very fine-grained sand are used in the dry mix. Dry mix technology plays an additional important role in reducing water consumption and plasticity. In order to make it impermeable, crack-resistant and highly adhesive, a water-soluble polymer is added to the dry mix to form an aqueous emulsion and not more than 5% of the dry weight. The dry mix, packaged in the amount given for the construction work, shall be mixed with a volume of water in accordance with the instructions for use and used as intended.

Packaging and labeling: Glue packaging should include labels and instructions for use. Packaged in paper or plastic bags or plastic containers with a layer of moisture and waterproofing. The basic packaging sizes are 25 kg and 50 kg, and in other packages, the weight must be written on the label. The amount of water to be mixed with the dry mixture shall be determined by the manufacturer and marked on the package. Subtract the average weight of the bag from the average gross weight of the bagged mixture to determine the net weight of one bag of mixture. The difference between the net weight of the mixture in the bag and the net weight on the package shall not exceed ± 0.1%.
