| Abstract: | 摘要： •Slump increases with the liquid–solid ratio and alkaline solution. Slump flow increased with the replacement of glass sand.•Compressive strength and ultrasonic pulse velocity decreased as the liquid–solid ratio increased, but increased with the alkaline solution and glass sand replacement.•Weight loss significantly increased in the first two cycle tests for sulfate attack, but the weight loss decreased in the third cycle due to the saturation of the internal porous crystal.•Waste LCD glass for alkali-activated material engineering properties of the impact supplement. This study used industrial by-product slag as the base material and applied different liquid–solid ratios (0.50, 0.55, 0.60), different alkaline solutions (0.5%, 0.75%, 1%) and waste LCD glass sand to replace the slag (0%, 10%, 20%) to produce mortar. The workability was analyzed. When the specimen was hardened, the engineering properties were tested at 3, 7 and 28days. The results showed that the slump increases with the liquid–solid ratio and alkaline solution. The slump was 100mm when the alkaline solution was 1% and the liquid–solid ratio was 0.50, which was higher than the slump when the liquid–solid ratio was 0.60 by 22mm. When the alkaline solution was 0.75% and the liquid–solid ratio was 0.5, the slump flow increased 1.26–1.67 times as the replacement of glass sand increased. The slump flow increased with the replacement of glass sand. When the liquid–solid ratio was 0.55 and the alkaline solution increased from 0.5% to 1%, the initial setting and final setting time were shortened by 45min and 100min. The compressive strength decreased as the liquid–solid ratio increased, but the compressive strength increased with the alkaline solution and glass sand replacement. The ultrasonic pulse velocity decreased as the liquid–solid ratio increased but increased with the alkaline solution and glass sand replacement. The weight loss significantly increased in the first two cycle tests for sulfate attack, but the weight loss decreased in the third cycle due to the saturation of the internal porous crystal.
