Ready Mix Concrete V/s Site Mix Concrete

In the case of site mixing, if the plant breaks down or materials are delayed, then all production stops but costs continue to rise, and the maximum output is fixed while the minimum output is uneconomic. The ready-mixed concrete producer on the other hand has the resources and technical expertise to produce a wide range of concrete mixes on demand to meet changes in the site programme and allow operator on-site flexibility in scheduling work. The truckmixers can deliver the concrete to the point of placing, with consequently cleaner sites and no wastage of materials. Costing ready-mixed concrete requires only an enquiry giving all the specification requirements to local producers. It is essential to ensure the concrete will have the correct qualities.

What is RMC ?

As the name indicates, Ready Mixed Concrete (RMC) is the concrete which is delivered in the ready-to-use manner.

RMC is defined by the American Concrete Institute’s Committee 116R-90 as:

“Concrete that is manufactured for delivery to a purchaser in a plastic and unhardened state”.

The Indian Standard Specification IS 4926:2003 defines RMC as:

“Concrete mixed in a stationary mixer in a central batching and mixing plant or in a truck-mixer and supplied in fresh condition to the purchaser either at the site or into the purchaser’s vehicles”.
