A way of producing lightweight aggregate concrete by using higher mW/mC was proposed. Two types of lightweight aggregates were used to prepare lightweight concrete. Variations of the slump loss, segregation of lightweight aggregates, and compressive strength of the concrete with different mW/mC were investigated. It is shown, when mW/mC is 075, a lightweight aggregate concrete with bulk density of less than 900kg/m3 and 28d compressive strength of 14MPa is obtained by using a coarse expanded shale with apparent density of 738kg/m3 and resulting fine aggregate by crushing. The shrinkage and water absorption of lightweight aggregate concrete, prepared by using higher mW/mC, are within an acceptable range. It is suggested that the lighter the lightweight aggregate, the higher the mW/mC, the less the segregation of the aggregate and slump loss of the concrete, and the higher the retained compressive strength.
