The difference between concrete and reinforced concrete

Concrete is included in the installation of modern buildings in a very large way, as it is an important part of the important architectural development and has become mainly relied upon in recent centuries. Through the article, we will learn about the difference between regular concrete and reinforced concrete.

Definition of concrete

Concrete consists of formations of fine sand and coarse sand with pieces of small stones and also a quantity of glass mixed with cement and water in certain proportions. These components are completely mixed in a specific form and this form is called concrete, and these components are a massive mixture of rubble with glass Therefore, this combination is strong.

How is concrete formed from these components?

When you add water to the cement, the cement begins to form and grow, and thus you control the bonding between gravel and sand together. This formation gives concrete its strength, which makes it dry. This soft, melted mixture that aerates from the cement mixer and then gradually turns within hours into a solid substance and increases in strength after about a month It continues to increase and writes to it full solidity after about five years.

Definition of reinforced concrete

Concrete cannot withstand tensile forces, and to solve this problem, liquid concrete is poured around strong bars called steel.

Reinforcing bars are often made of helical bars in order to increase the cohesion between them and the concrete and to prevent it from slipping. All types of materials can be used for one reinforced concrete in general, and we use reinforcing steel because it expands and contracts in the heat and cold to the same extent and that would not affect the entire concrete.

Concrete cancer definition

Cracks and cracks are the last thing you want to see in concrete buildings and bridges, especially completely new ones, but as long as we have what are called concrete structures, how about concrete bridges and skyscrapers themselves, which have stood for decades and many years to withstand and not collapse? There are many interpretations that confirm the Romans' use of Pozzolan concrete, which is made from volcanic ash and tends to crack less than other forms of concrete and is used mainly for compression.

Concrete cancer problems

1 - Alkali cement reacts with the silica in the sand, which is part of the concrete, then the crystals begin to grow more slowly inside the concrete, and this would take up more space than the original crystals, which makes the concrete crack from the inside out and peel away from the surface and allow water to enter.

2 - The water leaking into the concrete can rub against the reinforcing steel bars, causing rust and corrosion, and the concrete will also expand, causing weak points in the concrete structure. These spots are brown.

3 - The water that entered through the cracks will freeze in the winter, which means that it will expand and create additional cracks through which more water can pass through.
