Author’s blog on the repair and construction of cement.
The cement mixture is presented in the form of finely dispersed powder, which is obtained by sintering certain types of clay or their mixtures with limestone. When sintering, the addition of various slag, gypsum or sand fillers is added to the cement, the composition and proportions of which directly affects the characteristics of the finished cement. Using special additives, specialists can create cement that will have special characteristics and properties, such as frost resistance or fire resistance.
Due to their unique binding qualities, which allow you to create a high-strength structure, cement compositions are represented as the most popular binding materials that are only used in the construction of all kinds of structures. By the way, building a house must be used cement. Thanks to the marking of cement, you can determine the level of maximum load of hardened material under certain conditions. For example, if cement has a 300 brand, then the cement cube will be able to withstand about three hundred kilograms. The most common cement brands for construction are 350 and 500. In addition, cement freezes faster than other materials, most of the brands freeze on average in forty minutes, and complete hardening occurs in twelve hours.
