TECHNOGENIC WASTE AS A NEW INORGANIC BINDER

Abstract

Every year 9.2 billion tonnes of industrial waste are generated worldwide. This is waste from industrial manufacturing processes that’s often a by-product with no further use.In addition to occupying huge areas for disposal of construction waste, this waste pollutes land, water and air. Responsible industrial waste management is vital to reduce such risks. The paper presents the possibility of utilizing construction waste to produce a binding material that could be used instead of cement. In this paper, the mechanical properties of geopolymer based on fly ash from the "Stanari" thermal power plant near Doboj, granulated blast furnace slag from Arcelor Mittal Zenica, quartz sand, as well as the mechanical properties of Portland cement CEM I 52.5 N and cement with the addition of granulated blast furnace slag were examined. A mixture of water glass and 12 M NaOH solution is used as an activation agent for the preparation of geopolymer. Samples of portland cement CEM I 52.5 N, cement with addition of GBFS and geopolymer were produced and tested according to standard EN 196-1:1994. Geopolymers do not have high compressive strength values like cement CEM I 52.5, but they can replace cement in constructions with lower load capacity.Please do not change the given formatting.
