How can mortar problems be solved?

Ⅰ. What causes mortar water secretion?

1 The use of poor quality fly ash;
2 Low water retention of mortar; and
3 Unreasonable sand grading

Ⅱ. How to deal with mortar water secretion?

1 Avoid the use of poor quality fly ash; 2 Improve the water retention rate of mortar; 2 Improve the water retention rate of mortar
2 Improve the water retention rate of mortar.
3 Adjust sand grading

Ⅲ. What is the reason for the mortar drying and hardening too fast?

1 Increase the water requirement of fly ash.
2 Insufficient dosage of admixture.
3 Sand grading breaks;
4 Mortar water retention is too poor.

Ⅳ. How to avoid dealing with mortar dry dispersion?

2 Improve the admixture of additives.
3 adjust the grading of sand.
4 improve the mortar water retention rate.

V. What is the reason for the slow setting time after mortar on the wall?

1 Run wall serious interface layer does not absorb mortar moisture;
2 environmentally moist air convection slow.
3 humid environment, slow air convection.
4 mortar water retention is too good.
5 Mortar maintenance is too early.

VI. How to avoid the mortar not solidifying for a long time after it is put on the wall?

1 Avoid over-wetting the wall.
2 Keep the ventilation dry; 3Reduce the water retention of mortar.
3 Reduce the water retention of mortar.
4 Conserve the wall after it dries and hardens.

Ⅶ. What is the cause of blistering of mortar concrete wall?

1 Excessive mixing of fine sand.
2 Sand with excessive mud content.
3 too much mixing of cementitious materials.
4 Water retention of mortar is too good.
5 One-time plaster molding.

VIII. How to avoid the blistering of mortar on the wall?

1 Change the construction method and plaster in layers.
2 Reduce the dosage of cementitious materials.
3. Control the mud content of sand.
4 Increase the proportion of medium sand and reduce the dosage of fine sand.
5 Poke and compact leveling.

IX. What is the reason for excessive mortar viscosity?

1 too much fine sand mixed in.
2 sand with high mud and powder content.
3 overuse of adhesive material.
4 Excessive use of additives.

X. How to avoid excessive mortar viscosity?

1 Reduce the proportion of cementitious materials and fine sand.
2 Production control of sand mud content.
3 Adjust the admixture amount of admixtures.
