Bentonite For Foundation Constructiondelta_admin
The action of bentonite was first exploited by the oil industry for drilling and stabilizing wells after to use of casing.
Delta 500 or Delta 700 bentonite can be used automatically to aid diaphragm well placing ,pile driving ,caisson sinking and soil grouting.
In addition to advance construction, bentonite avoids the noise and vibration problems that influence conventional foundational operation urban areas.
Bentonite is like Portland cement, it must be stored under reasonably dry conditions .It is a very colloidal clay. In foundational work,the gel penetrates around individual soil particles and keep them in position by adhesion. Quality of bentonite needed for slurry of the water varies from about 4 % by weight for use in stiff clays to about 10 % by weight for open gravels. The preferred arrangement to incorporate bentonite is by high-speed stirrer for at least two minutes.
