Aug 05, 2015· "Concrete is a composite material that consists essentially of a binding medium within which are embedded particles or fragments of aggregates, usually a combination of fine aggregates and coarse aggregates; in Portland-cement concrete, the binder is a mixture of a Portland-cement and water, with or without admixtures."
Association (PCA) publication Design and Control of Concrete Mixtures is also a useful reference. II. Process At the start of the construction administration phase, it is a good idea to discuss the schedule for submission of concrete mix designs with the contractor in order to convey to him or her the
Concrete mixtures with high cement contents and low water-cement ratios (less than 0.40) may require special curing needs. As cement hydrates (chemically combining with water) the internal relative humidity decreases caus-ing the paste to self-desiccate (dry out) if no external water is provided. The paste can self-desiccate to a level where
Aug 02, 2012· The major source of information is AS3600-2001, the Concrete Structures Standard. To design and detail concrete structures correctly, the reader will need access to several other books and reference manuals. Some suggestions are given in the following pages. Recycling and restoration of older buildings is becoming more and more
Jan 01, 2002· This paper presents a method for model reference control of a cement-milling circuit that has been studied previously. The approach presented is based on the experimentally justified model developed by Breugesen (1996), and derives the form of control vector with the goal of driving the behavior of the system to that of a desired model.

Concrete has relatively high compressive strength (it doesn't crack under weight), but significantly lower tensile strength (it cracks when being pulled). The compressive strength is typically controlled with the ratio of water to cement when forming the concrete, and tensile strength is increased by additives, typically steel, to create reinforced concrete.
