What is Ready-mix concrete?
Ready-mix concrete is a type of concrete that is manufactured in a factory according to a set recipe, and then delivered to a worksite, often by truck. This results in a precise mixture, allowing specialty concrete mixtures to be developed and implemented on construction sites. The first ready-mix factory was built in the 1930s, but the industry did not begin to expand significantly until the 1960s, and it has continued to grow since then. Ready-mix concrete is sometimes preferred to on-site concrete mixing because of the precision of the mixture and reduced worksite confusion. However, using a pre-determined concrete mixture reduces flexibility, both in the supply chain and in the actual components of the concrete. (http://en.wikipedia.
