Abstract:
The construction sector in Ethiopia is growing exponentially, and we all know that there is a
huge demand for cement. Depending on the needs of the construction sector, various cement
factories are being built in observing at various options to reduce the high cost of cement in our
country is our biggest homework. Our country, but recently they have failed to meet this demand
and there is a serious shortage. Instead, we offer the use of beer by-products such as Kieselguhr
sludge. The kieselguhr sludge is the serious disposal problem for beer factory, the main objective
of this study is preparation and Evaluation of Physical and Chemical properties of brewery
Kieselguhr Sludge for partial replacement of cement for tiles production. Physical properties and
chemical composition of kieselguhr sludge was studied.
A total of 1,212,500 kg kieselguhr sludge per year was discharged to the environment only from
four beer factories with average moisture, loss on ignition and pH value of 0.474, 2.12 and 8.124
respectively. Chemical composition of kieselguhr, CaO content ranges from 0.9 % to 1.2% and a
total average value of 1.2%, Fe3O2 is varies from 0.67-1.13 %, Al2O3 content from 2.05 % to
4.65%, and average value of 3.4%, SO3 content of the kieselguhr ranges from 0.48 % to 1.2 %,
and a total average value of 0.87%, MgO total average value of 1.02%, was obtained from the
chemical analysis of kieselguhr.
