A study of the engineering properties of CLSM with a new type of slag

The slump, slump flow and tube flow of CLSM decreased as the replacement increased. The slump of the 30% replacement was lower than control group by 50 mm and the tube flow was 10% lower than that of the control group. When the replacement of the slag of BSSF was 10-30%, the setting time was 297-270 min, which was shortened gradually. The value of the ball drop of various replacements was 46-61 mm, meeting the specified value. The compressive strength before the age of 28 days decreased as the replacement increased. The compressive strength of the 40% and 50% replacements increased inversely from 56 days to 91 days. The replace up to 30% when the test body has up to 0.2% expansion, this time there have been many test body bursting point and partial damage, but still not the whole test specimen fracture.
