Mechanical and microstructural characteristics of high-strength self-compacting concrete (HSSCC) with optimal silica fume and fly ash cement replacement

This paper focuses on high-strength self-compacting concrete (HSSCC) characteristics with the optimal percentages of cement replacers, fly ash, and silica fume. The aim is to compare all the differing ratios of HSSCC mixtures with the aim of determining their durability. In the initial part of the s...
