<title>ABSTRACT</title>
<p>The Gotvand reservoir dam is located at SW of Iran where the Karun River orients
from the Zagros Mountains. The nominal volume is 5,500 million cubic meters. It is a
rock-fills dam with clay core. The height of crown is about 180 m with 130 m normal
water depth. Depth from bottom (0-30 m), the water layer’s electrical conductivity
(EC) will be as 150,000 to 85,000 mµ/cm. Also the EC will decrease from depth
(85-30 m) corresponding the water layer’s EC between 85,000 to 20,000 µm/cm.
Finally, at depth (30-0.0 m) the EC is controlled with values (15,000-1,000 µm/cm).
The salty domes will produce unexpected salty sediments into reservoirs. Consulting
engineering said that more than 8,000,000 tons of pure salt sediments were interned
into the Gotvand Lake reservoir from 2011 through 2015. If this regime of salty
material continues, downstream agricultural lands will completely disturb and disuses.
Turk salty concrete (SC) could present innovative solution to reduce salty feed in lake.
It is based on the chemical reaction of salt-clay-cement that salty volumes could be
stabled through special material injection inside the domes. Sliding resistance will be
increased by SC injection in the salty dome layers. Finally, the salty sediment should
be stabled by SC injection in the old mine Anbal salt dome. SC may be designed to
cementize salty domes through powder of bentonite clay, type-II cement, water, and
Shushtar ceramic clay.</p>
