Study on compressive strength of mineral admixtures and fibers to develop high performance concrete

Abstract

An experimental investigation was carried out to evaluate the strength properties of high performance concrete containing mineral admixtures and fibers. The paper presents a comparison of three mineral admixtures, Alccofine 1203 (AF), Metakaoline (MK) and Ground Granulated Blast furnace Slag (GGBS) on the strength properties of superplasticised high-performance concrete. Assessment of the concrete mixes was based on compressive strength of concrete on 7 and 28 days curing. The results confirmed that mineral admixtures improved the strength properties of high performance concretes, but at different rates depending on the binder type.
