The use of concrete is an important milestone in the history of construction

The use of cement and its subsequent connection with such materials as crushed stone, sand and water preceded the production of the latest building material such as concrete. In today's view, concrete is a raw material consisting of various cement-binding mixtures with the addition of various fillers. There is no doubt that the use of cement and concrete is a huge leap in the construction industry.  The concrete obtained later was much superior to Roman concrete in its properties and characteristics. The raw materials extracted from cement were completely unaffected by humidity and showed resistance to cold, fire, etc. Although modern concrete was ahead of its "brother" at the initial stage of invention with its qualities, but the basis of raw materials and the technology for its production were developed back then and are actively used to this day.

Modernization in the production of concrete occurs most often in the field of more accurate dosage due to modern mechanisms. Concrete mixers are being improved and the latest admixtures for concrete are being produced, which increase its quality. But in general, today there are no global changes in the production of modern concrete.

But in general, today there are no global changes in the production of modern concrete. Due to such characteristics as strength, rigidity, fire resistance, water resistance, etc. concrete has become widely used in design and construction. However, one of the disadvantages of concrete structures, such as insufficient resistance to tensile loads, reduced its use. Usually concrete was used in the construction of partitions and small openings. For our ancestors, the main material used in the construction of load-bearing structures was iron. Of course, iron products were characterized by good characteristics, but such structures in the open air were susceptible to corrosion and rust. Also, iron products were subjected to deformation and at very high temperatures - during fires. At that time, it was not even thought of trying to combine such building materials as concrete and iron. But the combination of these two materials and the appearance of reinforced concrete and reinforced concrete products (precast concrete) was already a matter of time.
