oa Civil Engineering = Siviele Ingenieurswese - A preliminary investigation of the engineering properties of concrete incorporating high-magnesia slag



High-magnesia slags ground to various finenesses were added at the mixer to yield concretes having standard aggregate to slag plus Portland cement, and water to slag plus Portland cement ratios. Cube crushing strength, modulus of rupture, elastic modulus, shrinkage and creep tests were carried out to determine the effect of incorporating various proportions of these materials. Concrete of good quality was obtained with slag to slag plus Portland cement ratios of up to 0.6 with slags ground to a specific surface of 4,600 cm2/gm as determined by the Blaine method.
