Abstract
In this paper, admixture factors affecting the properties of lightweight foamed concrete incorporating cement kiln dust(CKD) and fly ash(FA), respectively are discussed. Increase in CKD contents resulted in loss of fluidity and decrease in settlement of concrete noticeably. Moreover, the higher the unit weight is, the smaller the settlement depth is. The use of CKD resulted in slight decrease in compressive strength and tensile strength compared to that with other admixture. However, all mixtures met the requirement of strength prescribed in Korean Industrial Standards.
