Influence of curing conditions of glass fiber cloth on bonding performance:

Generally speaking, after the construction of cement-based materials, certain measures shall be taken for curing.

The effect of bonding mortar performance: from 24 hours after the face brick is pasted, the surface shall be cured with wet water for 7 consecutive days, twice a day. The bonding strength of the face brick bonding mortar is about 20% higher than that of the non-curing bonding mortar. The adhesive mortar for exterior wall external thermal insulation face brick developed by this system is modified by polymer lotion, which can meet the bond strength requirements without curing, but better bonding effect can be obtained by taking certain curing methods.
Effect of usable time of glass fiber cloth on adhesion performance

Figure 12 shows the effect of service time on the bonding performance of bonded mortar., With the extension of the usable time, the bonding performance of the face brick bonding mortar presents a downward trend, and the range is large. If the brick bonding mortar is used within the specified 4h, the tensile strength can reach more than 0.4MPa; If it continues to be used beyond the specified service time, its tensile strength drops sharply to 0 Below 2MPa, resulting in the failure of face tile pasting.
