DosThiox™ 85 Thixotropic Agent
DosThiox™ 85 is a thixotropic additive that helps manage lost circulation during cementing in cavernous or vuggy formations where bridging materials are ineffective. DosThiox™ 85 Thixotropic Agent is compatible with all types of Portland cement. DosThiox™ 85 is based on Aluminum Sulphate chemistry. This product is used to prevent lost circulation during slurry placement and is effective at temperature below about 85 °C.
Faster compressive strength development for set cement containing DosThiox™ 85
The figure below shows faster compressive strength development for set cement containing DosThiox™ 85 (Aluminum Sulfate solution) when compared to similar slurries with Calcium Sulphate hemihydrate at 52 °C.
|pH at 20 °C||-||1.8-2.8|
|Assay, as Al2O3||%||8-8.4|
