Construction technologies are developing rapidly. Today we already have such a variety of materials that we can browse through the offers endlessly. The situation is similar with respect to the available types of building gypsum. That's why below we present a complete guide to gypsum, which will help you navigate this topic.The basics of plaster
Construction gypsum, which requires low energy consumption in production processes, is produced by firing gypsum stone and is therefore present in a crushed form. It usually consists of raw gypsum, which is a natural mineral, or raw gypsum with factory-made additives. Thanks to these additives (for example, setting retarders, accelerators or consistency regulators), the properties of gypsum are enhanced and regulated. The additives also include fillers such as sand and perlite.Building gypsum requires certain conditions for solidification. It is always poured into water, not the other way around, so as not to spill, and it is done only in the air. After setting, at which the volume of gypsum increases, it hardens. However, it is not necessary to keep it wet, as is the case with lime and cement, because it can be dried immediately, and then it will gain full strength. Therefore, its main advantages are a fast hardening process and easy molding.Construction plaster: light and dark sides
Supporters of building plaster also inform us about other good sides of this product. Namely, it is a highly ecological material, because it is characterized by a low level of radioactivity. It also has a low bulk density and high porosity. Gypsum is also valued for its frost resistance and fire resistance. It also turns out to be a leader among building materials due to both the creation of appropriate thermal conditions in the room (good thermal insulation, maintaining a constant temperature) and the ability to regulate indoor humidity (absorbs moisture from the environment). it releases air and releases it in case of drying out).)The undoubted disadvantage of using construction gypsum is its high water absorption and solubility under the influence of moisture. As a result, it becomes unstable to changes in atmospheric conditions and therefore cannot be used for exterior plasters. It is also better to immediately protect the steel elements at their junctions with the plaster to avoid corrosion. The so-called rotting of plaster as an undesirable effect of its alternating moistening and drying. We also need to be careful in situations where we start laying it on concrete or on another surface with cement binder, because the substrate is still releasing water or some parts of it are wet, which contributes to damage.Therefore, it is worth remembering that it is not necessary to use building plaster. There are alternative solutions offered by manufacturers of construction products. We can safely use anhydrite or magnesia binders. Lime and cement can also be used as binders.Main Applications
Building gypsum has a wide range of applications. It is mainly used to cover walls and its main task is to smooth out irregularities. Certain types of building plaster can be distinguished precisely because of its various applications.One of the main types of gypsum is, first of all, stucco, used, as the name implies, for stucco work, products of various shapes and for work on a Chain link grid. It is also suitable for interior plaster and gypsum elements. It takes from 8 to 25 minutes for solidification to begin, which ends after 20-60 minutes, after which it should be stopped.There are other types of building gypsum based on stucco and/ or building gypsum, the special properties of which are achieved at the factory using regulators or fillers.For laying single-layer interior plaster with a thickness of 5 mm, gypsum is used for the finished plaster, which hardens slowly, and the time of its laying and processing from the moment of mixing with water is about 45 minutes. The following type of plaster has exactly the same properties as its predecessor. However, it has a wider application, as it is used not only for finishing single-layer interior plasters (5 mm thick), but also for smooth substrates with low suction, such as concrete surfaces. Of course, we are talking about plaster for adhesive tape. Plaster can also be produced mechanically using plaster aggregates, in which gypsum does not harden even with 15-minute breaks, and thanks to regulators, it can be laid for a long time. These are the features of the so-called gypsum for mechanical plaster, gypsum is also used for the manufacture of various plasterboard and their finishing. For embedding, the so-called dry plaster (drywall) is gypsum, which not only hardens slowly, but also has an increased water retention capacity, which prevents it from being absorbed by cardboard. On the other hand, a special gypsum for joints is used to connect plasterboard with mortar, the properties of which are exactly the same as those of the previous type of gypsum. In addition, we can use gypsum putty, which is used to fill not only the joints of gypsum boards, but also other smooth surfaces.Construction gypsum can also be used for special tasks, depending on the intended use, there are different types of gypsum, such as marble gypsum (marble cement), gypsum for modeling, insulating gypsum or lightweight (cellular) gypsum.
