What is the role of calcium formate in tile adhesive?

 

[Ankur]

Help with early strength in 24h.

 

[Cassie]

The cement hydration time is extended, the hydration efficiency is reduced, and the strength is slowed down when temperature is low. Adding calcium formate can effectively shorten the setting time of cement and increase the hydration efficiency, thereby achieving the purpose of rapid strength increase.

Accelerate cement hydration can shorten the construction period.

 

[Rony]

Calcium formate is generally used in winter when the temperature is low. Its function is to improve the early strengthen/accelerate setting and prevent the mortar from freezing before it sets.

Calcium formate is generally used in winter when the temperature is low. Its function is to improve the early strengthen/accelerate setting and prevent the mortar from freezing before it sets.

Generally speaking, it improves the early strength of the early mortar, including compressive strength, bonding strength, etc.; the most appropriate thing is to measure the early bonding strength, but most people consider measuring the compressive strength. Actually they are different.

 

[Alex]

Calcium formate is not only helpful for early strength, but also for later strength.

 

[Johnson]

Not only useful for early strength, but also helpful for adhesion, opening time, and workability.
The quantity should be larger. It can replace 2 kilograms of redispersible polymer powder, so it has little impact on the cost.

The role of calcium formate in mortar:

Early strength agent: Calcium formate has apparent early strength within 3 days, especially when the ambient temperature is within 0-10 degrees and the growth rate is more significant than 170%.

Accelerating agent: Accelerates the setting speed of mortar.

Binder: In mortar, calcium formate can improve the bonding force and be used in insulation boards and tile adhesives.
