Properties of ternary blended steel fibre reinforced concrete

摘要

Amongst the many known supplementary cementitious materials (SCMs), the useful ones for concrete are fly ash, blast furnace slag, silica fume, metakaolin, and rice husk ash. Their use with cement has led to the development of binary and ternary blended cement concrete depending on whether cement replacement is carried out with a single SCM or a combination of two SCMs. The main objective of this experimental investigation was to study the effect of ternary blends on the strength characteristic of steel fiber reinforced concrete. Both binary and ternary blends were made using SCMs such as fly ash ground slag silica fume, granulated blast furnace, and metakaolin. Thirty percent of cement was replaced by an SCM or combination of two SCMs. The results of compressive strength and tensile strength are presented.
