Description: synthetic marble which is resin binding with an
appropriate filler extender is an imitated substitute for quarry marble.
Synthetic marble products are industrially processed marble like imitation
products manufactured from composite chemical like polyester and inorganic
materials such as marble powder, limestone, granite, sand, etc. These
products have advantages such as longer life, better varieties of colors,
greater manufacturing flexibility and shorter production time. These
“man-made marble” are used mainly for commercial buildings, interior
decorations, sanitary fixtures, institutional premises, etc. Due to their
refractory and heat resistant characteristics, synthetic marble products
are used for hearth construction as well.
Potential: Synthetic marbles have been introduced to the Ethiopian
market during the last ten years. During this time, the use of synthetic
marbles has increased quite substantially in all major urban centers of
the country. Practically all sanitary fittings and interior decorations in
big building are made of synthetic marbles. As building construction of
all types is expanding in every part of the country, the demand for
synthetic marble is also expanding. The unit price of synthetic marble is
much lower than the price of natural or quarry marble. This is a major
factor to increase the demand for synthetic marble. According to a recent
study, synthetic marble is projected to have a demand of 435000 kgs. per
year in 2006.
of Raw material: Major raw materials required for the manufacture of
synthetic marble products are gelocat, panolyester, cobalt, butanox,
carnauba wax and filter materials which can be selected from a wide
variety of inorganic materials like marble powder, limestone, granite,
sand, etc. Raw materials such as marble powder, limestone, granite and
sand will be obtained from domestic sources; the rest will be imported.
and Technology: A polyester compound of a specific quality is mixed
with a cobalt solution (acceterator), filler and pigment. A solution of
peroxide (butanox) is added to the mixture in order to accomplish the
final chemical reaction. The filler material (marble powder and sand) is
added to the mixture after removing possible impurities. Setting up of
moulds is carried out at the same time. Prior to casting, the moulds are
treated with a releasing agent (carnauba wax) and then sprayed with a gelocat
solution. This solution provides the resistant layer of the finished
product. The prepared mixture is poured in the cavity formed by the appropriate
“male” and corresponding “female” moulds to cast the finished synthetic
marble product. During casting, the moulds are placed on a especially
constructed table equipped with small vibrating engines with ensure a
thorough filling of the cavity and adequate dispersion of the mixture.
After casting, demoulding and grinding of the cast take place. Finally the
products are polished and ready for marketing. The plant can also produce
synthetic marble for bathroom fixtures like wash basins, WC interior and
shower bases. It only requires the preparation of different casting
Machinery and equipment for the plant include about 24 units
and pieces. The most important ones are vibrator, moulds, spraying cabin, gel
coat equipment, air compressor, mixer, grinder, polyester exhauster, water
extractor with refrigeration, etc.
Investment: For a plant that will produce about 25,000 m2 or 500000
kgs. of synthetic marble per year, the estimated investment will be
Building/ shade 300 m2 at Br 2000/m2= 1,500,000
