A mixture of fly ash, slag, and WTS was activated using only NaOH to produce CLSM. Increasing WTS reduced the workability and increased the setting time of fresh CLSM. Adding WTS improved the strength and the water absorption capacity of CLSM. The performance criteria for CLSM were compressive strength, setting time, and flowability. Liquid-to-solid ratio and alkali equivalent affected the properties of CLSM significantly.
