Concrete is a composite material composed of fine and coarse aggregates that are joined to a liquid cement paste that hardens over time. In the past, for example, lime mastic, but also sometimes other hydraulic types of cement are a limestone-based cement binding agent. As a result of its visual similarity with Portland, such as calcium aluminum cement or Portland concrete.
The concrete and cement mixture forms a liquid lining that is quickly poured and formed by melting aggregate with dry Portland cement. Cement interacts with water and other additives to a hard surface matrix which connects the products to a sturdy stony material that requires several different applications. Additives for example pozzolans or superplasticizers are often included in the blend to strengthen the physical properties of the wet blend or the finished product. The bulk of concrete is packed with embedded refurbishing materials such as rebar to provide strength and to provide reinforcement concrete.
| Sl. No | Advantages of Concrete | Disadvantages of Concrete |
|---|---|---|
 |  |
|
| 1 | Concrete ingredients are readily available. | Concrete has to be hardened to prevent cracking owing to the poor tensile strength. |
| 2 | Easy handling and concrete moulding in any shape. | Expansion joints should be provided in long structures if there is a significant temperature variance in the area. |
| 3 | Easy transport from the mixing location to the casting location before starting setting. | Building joints are provided for the purpose of avoiding cracks due to drying and expansion of moisture. |
| 4 | Ability to cover holes and fill tunnels with a pump/spray. | Concrete soluble salts induce bloom when moisture interacts to them. |
| 5 | When strengthened, all types of structures from a common lintel to massive fly overflows are possible. | Concrete made from normal concrete from Oregon is blended with alkaline, sulphate and other content. |
| 6 | The monolithic character makes the structure look better and gives a lot of rigidity. | Sustained loads develop creep in structures. |
| 7 | The property of concrete with high compressive strength makes it more economical for a concrete structure than the structure of the metal. |
