OPTIMIZATION OF STRENGTH IN CEMENT PASTES

It has been demonstrated that porosity is by far the dominant controlling factor in limiting strength of hydrated cement paste. Mechanical means have been employed in the present study to minimize this porosity, "hot pressing" under rather modest temperatures and pressures, producing materials having very low porosity and unusually high strength. A new relationship to describe the interrelation of strength and porosity is given, and the effect of maturity of specimens, composition and microstructure are illustrated. Though theoretical density has not yet been achieved, the cement pastes have compressive strengths (as well as tensile and shear strengths) an order of magnitude higher than in normally hydrated cements, are stable and durable, and have dense interpenetrating microstructures.
