Keywords: High performance concrete; pozzolanic additives; silica fume; ternary systems. 1. Introduction Today, pozzolanic materials are enjoying a renaissance as supplementary cementing materials in Portland cements pastes and may replace part of the clinker in order to enhance the performance of the hydrated cement.

The principal factors affecting the abrasion resistance of concrete can be the environmental conditions and dosage of aggregate, the concrete strength, the mixture proportioning, the use of special cement, the use of supplementary cementitious materials such as: fly ash, the addition of fiber.

Typical stress-strain curves for various concrete strengths are shown in Figure 2. Most structural concretes have f'c values in the 3000 to 5000 psi range. However, lower-story columns of high-rise buildings will sometimes utilize concretes of 12,000 or 15,000 psi to reduce the column dimensions which would otherwise be inordinately large.
