Concrete Batching: A Voluminous Subject

But, as with modern concrete, Roman builders needed to revise the mix design based on the raw materials locally available to optimize the design for the specific building they were constructing. In the modern era, continuous mixing machines (typically employing a screw-type auger) were available for use in the early 1900s.

CHAPTER 1 COMPONENTS OF CONCRETE

mixing concrete than is required for complete hydration of the cement. This is required to make the concrete plastic and more workable; however, as the paste is thinned with water, its quality is lowered, it has less strength, and it is less resistant to weather. For quality concrete, a proper proportion of water to cement is essential.
