Ready-mix concrete (RMC) is produced at batching plants as per specifications of concrete and then transferred to the project sites.

Construction industries are responsible for 30 percent of the total global resources, 40 percent of the global energy consumption as well as 30 percent of the total greenhouse gas emission.

Corrosion-prone areas can be defined as the areas where chloride ions are available around a structure from seawater or other sources, such as de-icing salt which is used for melting of ice from the road surface to facilitate vehicle movement.

Worldwide consumption of concrete is estimated at 20 billion tonnes. To produce such a huge volume of concrete, we need 14 billion

Concrete is a widely used construction material all over the world. Buildings, bridges, tunnels and all of our infrastructures are mostly made of concrete. We may plan a structure for a 50 to 100-year service life.

Concrete is the second most consumed material in the world after water. It is estimated that every year 21 billion tonnes of concrete are consumed globally by 7 billion people. This large volume of concrete is used for making buildings, bridges, tunnels, roads, ports, and other infrastructures. Based on the place of casting, concrete is divided into place-cast or cast-in-place or cast-in-situ concrete and precast concrete.
