Investigation on the Mechanisms Governing the Robustness of Self-Compacting Concrete at Paste Level

In spite of the many advantages, the use of self-compacting concrete<br/>(SCC) is currently widely limited to application in precast factories and sihiations<br/>in which external vibration would cause large difficulties. One of the main<br/>limitations is the higher sensitivity to small variations in mix proportions, material characteristics...

The combined influence of paste volume and volumetric water-to- powder ratio on robustness of fresh self-compacting concrete

In order to avoid durability problems caused by an inadequate consolidation of concrete, self-compacting concrete (SCC) has been developed. The mix design of SCC aims at balancing a minimum flowability allowing air bubbles to escape and a maximum flowability in order to avoid segregation. Because of the higher demands on mix design and...
