There are more than 20 types of concrete, each with unique qualities that serve a specific purpose during construction. The following are some of the most widely-used types: Plain Concrete: This is the simplest kind of concrete and does not need reinforcement. The mixture usually contains cement, aggregates, and water in the proportion of 1:2:4. The concrete density ranges between 2200 and 2500 kg/cubic meters. Moreover, the overall strength falls between 200 to 500 kg /cubic meter. It is used in basic construction - building pavements and structures that do not require high tensile strength.

Ready-mix concrete (RMC) is a mixture of cement, sand, crushed stones, gravel, with water in the required proportion as per the requirements RMC is manufactured in a batching plant and then transfer via trucks. As the production of ready mix concrete is done under a controlled environment, you can expect the right consistency of the material even if it is produced in different batches.
