Strength Properties of according to the Red mud replacement of Lightweight Matrix based on Blast Furnace Slag

고로슬래그 기반 경량 경화체의 레드머드 치환에 따른 강도특성

This is an experimental study on manufacturing of non-cement matrix. Materials like cement and blowing agent in foamed concrete is replaced by by-products from blast furnace slag and paper ash. Further, the experiment was performed by replacing alkali with red mud by (0, 5, 10, 15, 25, 35, 45) of weight of alkali (wt.%) in order to reduce the amount of expensive alkali acclerator. Sample Plain with density showed lowest. The compressive strength test result, showed a similar trend with density. And it showed that compressive strength of the RM-0.05 was highest.
