Abstract
The use of a mini-aggregate iron ore concentrate uniformly dispersed in an inorganic cement matrix produces a structural product superior in many respects to ordinary concrete. Structural improvement is achieved, especially with respect to higher compressive and tensile strengths, and a significant increase in bond strength to steel reinforcement members is attained. Substantially the same strength can be obtained at all slumps.
