3.1.Pumices
Pumice is amorphous foam produced during volcanic
eruptions.It is constituted mostly of silica and alumina in
relative amounts varying according to the geological area
of origin,and also includes other chemical species,such as
different oxides and water [8].Pumice is a volcanic rock of
which porous structure is formed by dissolved gases
precipitated during the cooling as the lava hurtles through
the air.The connectivity of the pore structure may range
from completely closed to completely open [9].
Pumice is formed during explosive volcanic eruptions
when liquid lava is got into the air as a froth containing
masses of gas bubbles.As the lava solidifies,the bubbles are
frozen into the rock.Any type of igneous rock—andesite,
basalt,dacite or rhyolite—can form pumice given suitable
eruptive conditions.When larger amounts of gas are
present,the result is a finer-grained variety of pumice
known as pumicite.It is considered a glass because it has no
crystal structure.Pumice varies in density according to the
thickness of the solid material between the bubbles; many
samples float in water.The cellular structure of pumice is
created by the formation of bubbles or air voids when gases
contained in the molten lava flowing from volcanoes
become trapped on cooling.The cells are elongated and
parallel to one and another and are sometimes interconnected.
They may be small and big size [10].
During Paleocene and Quaternary,pumice deposits of
Isparta and region were formed after Go¨ lcu¨ k volcano
activity.Go¨ lcu¨ k volcano located on southwest of Isparta-
Turkey.Isparta’s pumice is obtained from the Isparta-
Karakaya region.Its apparent reserve is about 0.8 billion
m3,possible reserve is 1.2 billionm3 and total reserve is
about 2 billionm3 [10].
The main use for pumice continued to be as an aggregate
in lightweight building blocks and assorted building
products.Other major applications for pumice and pumicite
included abrasives,absorbents,concrete aggregate and
admixture,filter aids,horticulture (including landscaping),
and the stonewashing of denim.Imports were used
primarily as a lightweight aggregate,but a small percentage
of pumice imports were used in abrasive applications [11].
Crushed and screened pumice is used in the construction
industry in lightweight concrete,lightweight prefabricated
building elements,wall plasters and internal and external
masonry,and structural masonry elements.Pumice is also
used in denim and garment washing,polishing silverware,
glass,mirrors,and base metal,plastics manufacture (in
tumbling operations and operations where an abrasive is
required),manufacture of abrasive wheels,railway carriage
cleaning,as a floor absorbent,cosmetics,dental supplies,
pastes,face cream bases,when added to soap,it makes an
excellent exfoliating or scrub bar,etc.and pumice is
searched and used various other sectors.
