Concrete is the vitally used material in construction work. It has to be set and hardened by mixing water with it before using it. This hardness is caused due to a chemical reaction known as hydration. It helps you to bind different raw materials together. It is made by the mixing of several materials like cement, sand, stones, gravel, water, etc. All these components mix together to form a hard material. It is now the most used material made by man. It can be useful to us in making pavements, overpasses, motorways, the foundation of the buildings and houses, poles and fences, etc.
Working of cement. The different raw materials are mixed with water to make a liquid substance so that it can be molded. After setting up it in the molding casts, they become hard and rigid. In the modern world, the use of concrete has become a fact. It has various forms. One of them is porous or permeable concrete that can permeate water through it. For making such concrete, voids are entrapped in it. It has a compressive and tensile strength which helps it maintain rigidity. It is durable enough and does not easily rust or damages.
Use of concrete in construction. Concrete is an important material now and it needs high monitoring and control to improve its quality. Transport is becoming the fundamental aspect nowadays. For better concrete, we need to add less water. It will then show less permeability and high strength. Thus the prepared concrete is qualitative enough having fewer pores, normal resistance, formidable strength, etc. Admixtures are added to the concrete mixture to provide better strength and hardness.
What are the benefits of using concrete in construction work?
Economically affordable. As compared to other industrial materials, concrete is the most affordable of all. Also, it is available in abundance around the world. The major ingredients used in the formation of concrete are water, cement, and other aggregates. All these constituents are easily available in the market and at cheap prices.
Hardens at normal temperature. Concrete can be used only after it is hardened and well settled in its shape. And it does not need much effort. It can be hardened at regular room temperature. Thus it can be used all around the year irrespective of the climate or weather conditions.
Energy used in formation is less. It can be prepared at a low energy level if compared with steel. There is a slight difference between the amount of energy needed in the formation of plain concrete and reinforced concrete.
It can be easily molded. It can be cast into various shapes and figures when in a liquid state. Once hardened, cannot be reshaped. The concrete in the liquid state is put to set in the desired shapes.
Water resistible. It can better hold water without damage. This does not happen in the case of steel or wood. This being the reason behind its use in the formation of dams and underwater ideas. The pipelines, canals, linings, and other waterfront structures are made by this concrete itself.
Concrete is of great use nowadays. Whether it has to be put in use with the construction work or the removal of other pollutants. It can help us in various ways.
