In this paper, the durability and strength of self-consolidating concrete (SCC) is assessed through development and testing of six binary mixes at fixed water-to-binder (w/b) ratio of 0.36.

In each of the six SCC mixes, a different percentage of cement is replaced with fly ash.

Self-consolidating concrete allows for easier pumping (even from bottom up), flows into complex shapes, transitions through inaccessible spots, and minimizes voids around embedded items to produce a high degree of homogeneity and uniformity.

That's why SCC mixes allow for denser reinforcement, optimized concrete sections and shapes, and greater freedom of design while producing superior surface finishes and textures.
