Development of Self Compacting Concrete with Ternary Cementitious Blend Containing OPC, Silica Fume, and High-Volume Fly Ash

Abstract

Self-compacting concrete (SCC), alternatively known as "self-consolidating concrete" in North America, refers to a variety of customized concretes engineered to possess specific properties while in their fresh state. The standout attribute of SCC is its capability to seamlessly flow into formwork without segregation, relying primarily on its own weight. The key engineering traits of fresh SCC include resistance to segregation, excellent filling capacity, and exceptional flow split tensile strength and compressive strength ability. The suspension of particles within a matrix forms the fresh SCC, with the composite material's properties being influenced by a comprehension of how the mix composition and constituent materials interact. The composition of SCC varies significantly from country to country due to the availability of resources and amalgamation of local practices. Variations in SCC composition directly impact engineering properties such as strength, creep, durability, and shrinkage. Key challenges and opportunities associated with SCC involve aspects like flow modeling, virtual mix design, robustness, sustainability, and the compatibility of constituent materials.
