Black cotton soils are soils that expand when it becomes wet it
gets expand and when it becomes dry it gets shrink . This
continuous expansion and contraction will decreases its
strength.,. Foundation with swelling soil will heave and can
cause lifting of a building or structure laid on it whenever
the moisture content rises.
expansive soil consists of mineral like smectite, bentonite,
montmorillonite, beidellite, vermiculite, attapulgite,
nontronite, illite and chlorite. There are some amount of
sulfate salts which will expand due to changes in temperature.
Soil containing above mentioned expansive minerals, they
tend to possess significant expansion or swelling.
Iron ore tailings which is the waste products of mining
industries is used as an alternative to the river sand in the
manufacturing of concrete. The KIOCL company which is
one of the growing company in our country in mining of iron
ore. This company used to dumpat lakya dam around 200
million at metric tons of iron ore tailings . TheKIOCL
company has conducted mining for more than 25 years in
Kudremukh. The company has stopped mining in 2005,
2. MATERIALS
Iron ore tailing which is having bulk density 1594 kg/m3
and the fineness modulus 2.53 was used in the project work .
The specific gravity of the IOT was found to be 2.85and
which is suitable for concrete works. The gradation of the
used particles falls within the fine aggregates

Design of tailings disposal can be carried out without an
appreciation of the physical nature and chemical
characteristics of the iron ore tailings. Plant effluent, physicchemical
properties of the material dictate on the most
fundamental level, the type of disposal facility required and
the degree of conservation in its design, consistent with the
hazards posed by the materials understanding of tailing
effluent involves knowledge of the processes through which
they are produced.
