This study was conducted examine the workability of LEFC in relation to unit quantity of water and fiber addition. The LEFC should secure low weight and good flow by mixing light weight aggregate because the fresh concrete should cured so that gaps do not form between the acrlyic wedges and the concrete with the fresh. The slump tests revealed that fresh concrete with 180 units of water and 0.1% fiber content and fresh concrete with 190 units of water and 0.1%, 0.2% fiber content respectively had excellent workability.
