Effect of bottom ash powder replacement rate, water cement ratio and sand cement ratio on alkali activated slag mortar.

5 b, it is evident that the fluidity of AASM demonstrates an increasing trend (61 mm to 224 mm) with an increasing water-cement ratio (0.38 to 0.47), consistent with the findings of Dong J et al.

5 c, it is observed that the fluidity of AASC exhibits a decreasing trend (276 mm to 139 mm) as the sand-cement ratio increases (2.2 to 3.4).

8 c, it can be seen that the pH showed a trend of decreasing, then increasing, and finally decreasing with the increase in the curing age, regardless of the sand-cement ratio.
