Development of a self-compacting lightweight concrete

Okamura with reverse signs

Despite its positive properties as a material (low dead weight, good physical properties, etc.), lightweight concrete is only rarely used as in-situ concrete in building construction [1]. One reason is the more difficult conditions during placement and compaction compared to normal concrete. Almost regardless of the procedure chosen and the level of experience of the performers, visual defects are a common consequence. One approach to remedy this could be the use of a lightweight concrete with self-compacting properties (here: SCLC), which combines the advantages of a structural lightweight concrete (LC) and a self-compacting concrete (SCC). The prerequisite is the unerring producibility and thus a reliable development methodology of such concrete.
