Abstract:
Criteria of strength of concrete and other solids are discussed with reference to the behavior of neat C3S pastes, porosity, pore-size distribution, and Griffith flaws. This is followed by a consideration of bonds within the cement paste; the absence of their influence on its modulus of elasticity is noted. The two-phase nature of concrete is reviewed in some detail. In considering impregnated concrete, attention is drawn to the disparity between the coefficients of thermal expansion of sulfur and of other concrete materials. A proper basis for evaluation of polymer-impregnated concretes is discussed, with special consideration of the effects of impregnation on the compressive and tensile strengths and on the modulus of elasticity. Consideration of the durability of sulfur-impregnated concrete with respect to freezing-and-thawing and to chemical attack leads to a positive evaluation of this material for many purposes.
