Burning material is one of the basics of building and plaster types of solutions that are used today in the construction sector. Gypsum, lime, clay, cement are all those substances that over some time or under the influence of some factors in the form of elevated temperatures or simply harden over time. One of the most common additives is lime, which is natural and at the same time very often used as an astringent material. Gypsum is the fastest drying material, which is also used in almost all construction and plastering construction mixtures. Cement is also very often used in building dry mixtures, which is simply an amazingly universal element, which is used very widely in connection with its rather diverse properties. For home conditions, the cement of the brand «500» is most likely as much as possible. If pure high -quality cement is mixed with water, then after hardening it will turn into a homogeneous stone that, with complete hardening, can be broken will be very difficult. In order to freeze the cement more firmly, it is recommended to constantly water it with water, from which it only becomes blue and hard. Construction gypsum is often used as a binder in a plaster type of dry mixtures. This astringent material is almost never used in external work, and usually in tandem with gypsum the filler is fine sand. Plastering dry mixtures is a completely different category of mixtures, where it is customary to indicate the ratio of substances that are used in these mixtures as a fraction in which the numerator is a knitting substance taken as a unit, and the denominator is a filler in the form of sand.
