By nature, concrete is a brittle material. It has high compressive strength and low tensile strength. During construction, reinforcement mesh is usually embedded in the concrete in order to enhance the tensile strength. This does not only strengthen the entire structure but also it minimizes its chances of cracking.
Characteristics of a good reinforcement material
Reinforcement mesh is an important construction material used in the construction industry. At times, it is used to make reinforced concrete. This material has a size and shape that allows it to be placed within the concrete with ease so as to make a monolithic structure. It can easily be bent into various shapes so as to perform its functions efficiently.
Steel in the form of either mesh or bar is commonly used as reinforcement. It has a thermal expansion similar to that of a concrete. This characteristic makes it one of the best reinforcement materials available. The concrete mesh is also used as reinforcement owing to its ability to bond perfectly with the concrete.
High compressive strength in concrete comes from crushed rock and sand present in it. These are important components because they give the concrete the ability to support heavy weights. Compressive strength is usually dependent on the number and the hardness of the rocks within the concrete.
Slabs break or crack owing to less tensile strength. Sand and rocks present do not contribute anything when it comes to tensile strength. This force comes from cement and it is usually much less compared to the compressive strength that comes from the other components.
The problem brought about by the weak tensile strength of the concrete can be solved using concrete steel mesh. Reinforcing concrete is highly recommendable because it acquires the ability to withstand negative effects of forces that may be subjected to it. Before you start dealing with concrete, consider knowing its weaknesses and strengths.
History of reinforcements
In the olden days, there were no reinforcements used during construction. Builders started using cast iron as the reinforcements during the 18th century. People liked them because of their high quality and ability to resist corrosion. In the 1960s, steel bars were introduced hence replacing the cast iron. They had a mild strength and were phased out afterward due to the inefficiencies they had.
Later, improved and stronger steel bars were produced. This was done by raising the manganese and carbon contents in them. Another type of bars was introduced in the 1970s. They were not only stronger but also were much durable compared to the previous ones. Nowadays, people use modern reinforcements while constructing structures such buildings and roads.
Factors to consider when choosing reinforcements
If you really want to have a durable and sound concrete structure, you must use reinforcement mesh of the right quality and characteristics. Features of reinforcements such as driveway mesh are dependent on the chemical composition of materials they are made from and their physical properties.
Reinforcements are usually classified into two. Primary ones give a structure the resistance needed to support loads of the design. Secondary reinforcements are very helpful when it comes to matters regarding aesthetic and durability. They also mitigate problems brought about by changes in temperature.
