Concrete is basically a mixture of Portland Cement, water and aggregates comprising sand and gravel or crushed stone. In traditional construction sites, each of these materials is procured separately and mixed in specified proportions at site to make concrete. Ready Mix Concrete, or RMX as it is popularly called, refers to concrete that is specifically manufactured elsewhere and transported in a Transit Mixer for delivery to the customer's construction site in a ready-to-use freshly mixed state. RMX can be custom-made to suit different applications. Ready Mix Concrete is bought and sold by volume - usually expressed in cubic meters.
The use of RMX is an environmental friendly practice that ensures a cleaner work place and causes minimal disturbance to its surroundings. This makes its utility more significant in crowded cities and sensitive localities.
In contrast to this, conventional methods of making, transporting and placing concrete at most construction sites are somewhat labour-intensive and suffer from practices which may be erratic and not very systematic.
Therefore the use of Ready Mix Concrete can prove to more cost effective in the longer term while ensuring that structures are built faster and using concrete that comes with higher levels of quality assurance.
