Dry mixes are very widely used in construction. There is a large selection of materials that have different purposes. Dry grouts are used for grouting, waterproofing, tile and natural stone stickers. Sand-cement mixture is used for plastering, masonry, leveling floors, creating a flat surface.
Composition
All cement-sand materials are made on the basis of cement of different grades: M400, M500, M600. But this is not just a mix of cement and sand. An astringent is used as a special component . In order to give softness to the plaster mixture, a plasticizer - lime is added to it. The sand-cement mixture, which is used for screed, incorporates a water repellent. All these and other components added to dry materials have been tested in laboratories with modern equipment. Some additives have a directed action for a specific type of work. It should be noted that all modern compositions are of high quality. Some of them are universal, others have a special purpose.
Price
All mixtures existing in the domestic market are cheaper than materials imported from abroad. Sand-cement mixture is expensive for the manufacturer, since the process of its production is quite complicated. That is why there are so few companies on the market that produce high-quality modifiers. The price of the product depends on those chemical additives that are part of the dry materials.
Quality
In order to get a good result during construction work, it is necessary to apply high-quality material. Of course, factory imported finished plaster is much better than sand-cement mixture of domestic production. The thing is that mineral fillers, binders, additives do not always have the proper quality. This also applies to sand, which makes up the bulk. Domestic manufacturers study and compare dry formulations of different brands, equaling advanced manufacturers.
