About Project

Thanks to its pure, homogeneous and natural structure, Our Bentonites are used in long-lasting structures, sealing curtain and impermeable wall construction, impermeable building wall construction and load-resistant building walls, bored pile applications, TBMs, injection processes.

ADVANTAGES

Preventing precipitation in injection liquor is as important as providing fluidity.
For this purpose, bentonite is added to the mixture at a high rate (5% of the cement).
Bentonite clay increases the shear threshold significantly and plastic viscosity relatively slightly.
It is assumed that this situation is due to the sliding property of bentonite (also called lubricating effect).
The plastic viscosity determines the flow rate of the slurry, and the shear threshold determines the maximum transmission length.
Thus, bentonite limits the volume of grout during flow.
However, plasticizers reduce the shear threshold to a large extent and the viscosity to a relatively low level, as a result, the flow rate increases and the injection process is completed in a short time.
This should not mean that the lubricating effect of bentonite is not as important as adding a plasticizer.
Because it should be accepted that the function of providing slurry stability of bentonite is still valid.
Especially if the rock cracks are large, fine sand is added to the slurry.
The addition of approximately 0.5% bentonite to such sandy grouting mortars prevents precipitation.

* When added to cement grout or mortar; It keeps the cement particles and sand suspended during mixing and injection and ensures the stability of the mortar.
* It minimizes the separation of water in the cement-water mixture.
* When mixed with cement grouts, it increases the degree of penetration into fine grained alluvium. Thus, cement loss is prevented. Mixtures act like a fluid, when mixing is stopped, homogeneous hardening occurs and high strengths are achieved.
* Repairs cracks in walls made to prevent water infiltration. It provides slipperiness to the cement grout and increases the penetration of grout into fine cracks. In order to plug the crack, it is mixed with water at a ratio of 1/1 and plastered with a trowel and tarred.
