Maintaining uniform quality of concrete is a challenging task in the construction industry. Good quality of concrete with high speed of construction is not achieved by manually mixing of concrete. Manually mixing of concrete needs labour management so that more time, efforts and money. To overcome limitation of ordinary mixtures to reduce the work site, to avoid site confusion, Ready Mix Concrete (RMC) is a great solution.
The word Ready Mix Concrete (RMC) itself implies that it is ready to use materials, with a predetermined mixture of cement, sand, coarse aggregates, water and admixtures. Ready-mix concrete is the concrete that is manufactured in a factory or batching plant, according to a set recipe or as per standard specifications under controlled conditions using superior quality of raw materials, and then delivered to a work site without affecting its fresh properties.

Ready mix concrete is an advanced technology having a high degree of mechanization and automation. The raw materials are tested in the plant before they are used to ensure compliance with relevant standards. These eliminate the possibility of quality problems in the product. The proportions of various constituents in the concrete mix are designed scientifically considering the required strength and other properties of concrete and economy. This is called concrete mix design.
Ready mix concrete also avoids the concrete related problems particularly of fresh concrete such as workability of the concrete, segregation of concrete and bleeding in concrete, those mostly happening in traditional mixing concrete.
The ready mix concrete is transported in specially designed truck mounted mixer called transit mixer whereas the concrete is kept under continuous agitation until it is taken out for use.
In all the developed and most of the developing countries, use of RMC for construction has enabled the achievement of speed and quality in construction.
In recent years, it has become the favored choice of architects and civil engineers.
Concrete as much as a major structural material and therefore plays important role as far as safety is concerned with use of fly-ash slowly it also becoming a green material.
