Bentonite in civil engineering used for waterproofing screens, basement construction, “diaphragm wall” technology, casing pipes and tunneling.
Due to its adsorptive properties bentonite is highly used for construction of waterproofing curtains and as waterproofing material in products like “bentomats” and “bentocords”.
Bentonite possesses excellent plasticizing and penetrating properties and used in injection and cementation mixtures for plastering clefts and filling cavities. That is why it is used in construction of HPP, seawalls and canals, ponds, substructure of residential and industrial buildings.
Bentonite powders for civil engineering have the following quality characteristics:
|The properties of bentonite suspension at a flow rate||kg/m3 ||60|
|Indicators Fann viscometer speeds 600, not less|| ||40|
|Filtration, not more||cm3||14|
|Wet tail 0,071, not more|| % ||2|
|Marsh funnel viscosity||sec||37-45|
|Gel strength (Kyugel balls)||Pa||20-33|
Production technology of «AzRPI» JV is covered by patents.
Bentonite powders are packed in Big Bags 950 kg and shipped in bulk in gondolas.
Bentonite clay is shipped from Gazakh station of Azerbaijan railway.
