Mix Design - Self-Consolidating Concrete

Mix Design . SCC looks very different from conventional concrete while mixing. Concrete producers must “retrain their eyes” for this very fluid mixture as it turns corners and fills forms. Traditionally, concrete with the fluidity of SCC has had a very high water-to-cement ratio, which would lower compressive strengths and compromise ...
