Abstract:
options available for the color, shape, texture, architectural style, and structural systems available through use of this material concrete. But the excitement (and often the anxiety) that accompanies concrete construction is due to the rapid changes associated with concrete's transition from a fluid-like, workable material that is similar to a saturated soil to its ultimate status as a brittle, artificial rock. The engines behind this transition are the hydration of the portland cement and reactions with other cementitious materials. While cement hydration is often considered to be of interest only to those in white lab coats, these chemical changes at microscopic level are played out in the "real world" in terms of the effects of mixing time, rate of slump loss, form pressures, time to start and end surface finishing, and the rate of increase of both strength and stiffness.
