Abstract
As with all materials, the performance of concrete is strongly influenced by its physical structure. From its earliest origins, however, the performance of cement-based materials has also been controlled by the judicious addition of supplemental chemicals. From the examples discussed in this article, it's clear that the engineering of concrete performance has historically used both physical and chemical approaches. Future engineering efforts will almost certainly maintain this tradition.
