MECHANICAL PROPERTIES OF HIGH PERFORMANCE CONCRETE WITH ADMIXTURES AND STEEL FIBRE

This paper presents comparison of three mineral admixtures, Alccofine 1203 (A), Metakaoline (MK) and Ground Granulated Blast furnace Slag (GGBS) on the Mechanical properties of High Performance Concrete (HPC). Assessment of the mechanical properties of concrete mixes was based on compressive strength, split tensile strength, flexural strength of concrete and durability tests. Tests were carried out after first24 hour warped curing and then water curing. The results, in general, showed that mineral admixtures improved the properties of high performance concretes, but at different rates depending on the binder type.
