An approach to formulate suitable lightweight self compacting concrete

The knowledges and feedback on self compacting concrete (SCC) and lightweight concrete (LWC) open the door to a new set of concretes: the lightweight self compacting concrete (LWSCC).

This study aims to develop a rational mix design method for suitable lightweight self compacting concrete. The approach is built around a set of data (compaction index of granular skeleton, experimental data such as water absorption in the cement paste and segregation). From this method, different ranges of LWSCC have been developped to meet the requirements of the specification in terms of properties at fresh state dry density, compressive strength.
