Supplementary Cementitious Materials (SCMs) market share in ready mix concrete industry has been significantly increasing during the past 2 decades. SCMs as silica fume, fly ash, quartz flour, and blast furnace slag are currently used in partial replacement of conventional portland cement to improve mix properties including flowing ability, compressive strength, modulus of elasticity, and long-term performance. The main advantages of SCMs are attributed to the contribution of SCMs to the formation of additional concrete binder and the improved packing order of the cementitious material matrix.
Due to the afore-mentioned advantages, SCMs have been used in developing ultra-high-performance concrete, also known as reactive powder concrete. SCMs are successfully used in developing non-proprietary high-performance mixes used in high-rise construction and in fabricating high performance precast/prestressed bridge girders for new infrastructure projects. This paper displays the advantages of SCMs, and present different proprietary and non-proprietary mixes developed by incorporating SCMs, and their effect on different concrete properties. The wide spread of SCMs in concrete industry would potentially increase construction projects life span and minimize the need to routine maintenance.
