This study was conducted to examine the workability of LEFC in relation to the types and the mix ratio of different foaming agents. The foam agents act as lightweight aggregates in the concrete matrix and provide an alternative to obtaining the adequate strength level for the foam concrete. The results of the test showed that the synthetic foam agents were able to act properly as replacements for the lightweight aggregates.
