If you have a lot of construction, then, I think you can not do without concrete. After all, even in our age of innovation analogue there is simply no material. But how to choose real concrete with delivery price in Moscow and the Moscow region with its current variety? About this and much more – further!
During the manufacture of concrete, cement, sand, crushed stone and water are mixed. The more water and cement in this mixture, the stronger the concrete will be.
When choosing concrete, you need to be guided by many indicators, for example, strength, water resistance and corrosion resistance, frost resistance. Strength is the most important indicator, because due to resistance to high loads, it became popular. Checked by subjecting huge loads using the press. Usually strength measured in kilograms of force on KV. centimeter or in megapascals, written on the package. Frost resistance should be studied more quickly to those who are going to use it in harsh climatic conditions or on the street, because its frost resistance is determined by alternating subject to low temperatures and higher, that is, imitation of winter and spring.
Water resistance is also an important indicator, because many use concrete in bathrooms or also on the streets where multiple contacts with water occur. The water resistance is determined by assessing the resistance of concrete to sewing water through it. Both indicators are checked by special climatic cameras. Corrosion resistance is also called a sort of “service life”, because it shows how concrete, which is under the influence of aggressive conditions, for example, contacts chemicals.
You can also chemically modify concrete using special mixtures that help to compact concrete, as a result of which all its indicators increase for the better. Concrete is not combustible, environmentally friendly, durable, not susceptible to mold, fungus. Concrete prices vary, for example, the M-500 brand is more durable, and therefore more expensive. And, conversely, the M-100 is cheaper, but inferior in terms of strength characteristics.
So, when choosing concrete, you need to be guided by these indicators, because the success of the construction itself depends on the choice of good concrete.
