| When you read a touristic guide of any city, in 90 % of cases you will see a sentence - the town is well-known for its outstanding architecture. Architecture reflects the essence of the city, of its background and mentality of people living in this city. People who don't know much about the sphere of construction generally think that all the constructions are built according to the same projects. But it is totally untrue. Architecture is a branch of art. It demands not just mathematical thinking with the aim to calculate all the details, but an artistic approach as well.
Contemporary architectural specialists use various materials to implement their ideas – cement, stone, crushed rock, sand, reinforcing steel. The combination of different materials helps to make the construction not only reliable, but original as well. But still, reinforced concrete elements still constitute the most economically sound materials in construction activity. Concrete is a strong construction material composed of cement and other materials such as slag cement and fly ash, chemical admixtures and water. It is the most frequently used man-made construction material in the world. Concrete is also called an artificial stone material as concrete constructions are known for their high-class reliability.
Concrete can be used as it is as it is a strong material, but in the recent years there is a trend to the application of reinforcing steel to make the construction even more reliable. It's frequently applied in road and building construction, bridges, electric substations, stairs construction, retaining walls and formwork, as well as for other purposes. Concrete mixtures may be prepared in different strength levels depending on its construction purpose. What is particular about concrete, there is a possibility to add virtually any color in the concrete mix before it becomes hard. This way, you have a possibility not only to obtain a strong and safe material for building, but to make it look according to your design. |
