Experimental research on the use of industrial waste as addition for the production of unfired clay bricks

Abstract

Since ancient times we know the efficiency of the technology of building houses using clay soil in various forms: mixed, in the form of bricks, etc. Until now, there have been numer-ous studies to improve these technologies and to obtain structures that are as resistant, com-fortable and durable, as well as for the recov-ery of industrial waste. This paper presents an experimental study on the possibility and effi-ciency of the addition of industrial waste in order to obtain suitable clay mixtures for mak-ing unfired clay bricks. For this purpose, 6 compositions based on clay and industrial waste have been made. The industrial waste was ash from Mintia (thermal power plant), limestone sludge, plaster sludge and dumped waste from the processing of imported ore. Analysing the followed physical-mechanical parameters, for the realized mixtures, it is con-firmed that the industrial waste can be suc-cessfully used as an addition in the clay ma-trix destined to make bricks from unfired clay.
