Bentonite is used in grouting applications as it has several properties that make it well-suited for this purpose.
Fluid loss control: Bentonite can be used in grout formulations to control fluid loss. This helps to ensure that the grout stays in place and does not seep out of the intended area.
Rheology control: The addition of bentonite to grout can help to control its flow and improve its stability. This can be particularly useful in applications where the grout needs to be pumped into place.
Lubrication: Bentonite can provide lubrication to grout, making it easier to pump and reducing the risk of blockages or other issues during application.
Set time control: Bentonite can also be used to control the set time of grout, allowing it to be tailored to the specific needs of the application.
