Concrete is a popular building material that has been used for centuries due to its strength, durability, reflectivity, and versatility. It is a reliable and durable choice for many domestic and commercial environments, as it has a 100-year lifespan and requires few repairs and little maintenance. Concrete is used to provide strength, durability, and versatility during the construction of a structure. The use of concrete in construction has many benefits.
It is not as cheap as wood, but it is more durable and resistant to water and fire damage. It's not as strong as steel, but it's not as expensive either. The flexibility of concrete also means that it can be used in all types of projects. Concrete is a vital element and a vitally important thing that is used in various individual and commercial buildings.
It solidifies and hardens after mixing it with water and placing it due to a chemical process known as hydration. It is a material widely used in the construction process and is manufactured by mixing aggregates, cement, small stones, sand, gravel and water. All components are joined together to create a stone-like material. After water, concrete is the most commonly used substance on Earth.
If the cement industry were a country, it would be the third largest emitter of carbon dioxide in the world, with up to 2.8 billion tons, second only to China and the US. Buildings built with concrete are easy to reuse and adapt to new uses. This is because concrete is strong and resistant to fire. When buildings are reused rather than abandoned, resources are conserved and the environment is preserved. The main uses of concrete are: the use of concrete in commercial buildings makes it safer than the use of most other building materials.
It is mostly cheaper than steel buildings and requires less maintenance. It is easy to control heat transfer from the inside to the outside and back, reducing the energy consumed. This is a special type of reinforced concrete in which the reinforcing bars are tensioned before they are embedded in the concrete. This type of concrete is prepared in concrete plants and/or transported with the help of truck-mounted transit mixes. So, if added to the concrete mix, tiny pore spaces can be reduced, resulting in high-strength concrete.
Because of this property, concrete is ideal for submarine and submerged applications, such as building structures, pipes, dams, canals, coatings and waterfront structures. When a concrete building is burned, concrete walls and foundations, as well as floors, always remain standing. When recycled glass is used as an aggregate in concrete, this type of concrete is known as glass concrete. The construction of small buildings, villas and even high-rise buildings is carried out using concrete with traditional or modern formwork as a method of constructing the skeleton from the foundations to the slabs and columns and beams. The versatility of concrete has been taken to new heights with the increasing popularity of innovations such as photocatalytic concrete, ultra-high performance concrete and permeable concrete. The result is that when the concrete sets and hardens, all the concrete members so that the mold is compressed.
Before the introduction of cement into the construction world, lime concrete was the most widely used type of concrete. The first concrete dates back to around 500 BC which serves as great proof that concrete is very durable. There are different types and grades of concrete available on the market which can be obtained from suppliers such as Hanson Malaysia. In addition, concrete contributes to the compressive strength of reinforced concrete members and structures. Pumped concrete is used in high-rise constructions where there is likely to be no other feasible means of transporting concrete. Typical concrete with a normal water-cement ratio always has micropores which limits the strength of normal concrete.
