Each of us dreams of his house to be a real fortress and last a lot of years. If you look at the old castles that have survived to this day, it becomes clear that they have been built for centuries, using the best materials for construction. Among them were analogs of modern cement.
Description of the article:
The cement that we know and use in construction was invented in 1822. Its creator was the Russian builder Cheliev, who was the first to make a cement mortar of clay and lime. This historical fact was captured in his book, where he described the advantages and disadvantages of using the cement he invented in the construction process.
Cement production
After a couple of years, the English scientist aspind patented his production cement. Its way to manufacture this basic building material had its own characteristics: the master took lime dust and clay in certain proportions, mixed them and heated at high temperatures. The material obtained as a result of this processing was called the clinker and, chopping it and adding water, Aspind received very strong material for construction, which soon gained popularity around the world.
Soon, several factories for the production of cement were built on the territory of Russia.
Cement mixture
Today no one is represented by any construction without the active use of a cement mixture. The main valuable characteristic of the cement is its strength – “for conscience” the made material passes through the test of time, lasts a very long period, without losing its qualities. In construction terminology, to indicate the degree of strength of cement, use the capital letter M. If the composition of the cement mixture includes various additives that improve its quality, then on bags with material there is an indicator with the letter D.
The quality of cement
The valuable qualities of cement are frost resistance, resistance to corrosion and the influence of water, therefore it is actively used in construction for laying the walls of the building, during the external and interior decoration of the room, for laying the base of the floor, for flooring and D. T. Today, no construction solution is complete without cement. Cement is actively used for brickwork. In addition, it is a component of concrete and reinforced concrete. In order to make building material more durable, steel reinforcement is added to the cement – this process is called reinforcement, as a result of which reinforced concrete is obtained.
Using the highest quality cement mortar, we can hope that the buildings we built will serve for a long time.
