Application and Performance Study of Lithium Mica Lithium Slag Powder in Door and Window Frame Filling Mortar
In order to improve the comprehensive utilization rate of lithium slag,an experiment was conducted to replace fly ash in door and window frame joint filling mortar with lithium mica lithium slag powder.The influence of lithium mica lithium slag powder on the standard con-sistency water consumption,density,water retention rate,and 28 day compressive strength of door and window frame joint filling mortar was studied,and the optimal dosage of lithium mica lithium slag powder in door and window frame joint filling mortar was determined.The research results indicate that lithium mica lithium slag powder can significantly increase the standard consistency water consumption of door and window frame joint filling mortar,reduce water retention rate,but has no significant effect on the density of door and window frame joint filling mortar.At the same time,it can effectively improve the 28 day compressive strength and 14 day tensile bonding strength of door and window frame joint filling mortar.Taking into account the impact of lithium mica lithium slag powder on the workability and mechanical properties of door and win-dow frame joint filling mortar,it is determined that lithium mica lithium slag powder can completely replace fly ash in door and window frame joint filling mortar.
