“…U 2010. godini je u Europskoj uniji na drvo i drvni otpad otpalo ukupno 49 % od ukupne potrošene energije proizvedene uz pomoć obnovljivih izvora u EU [3]. Republika Hrvatska ima velik potencijal biomase kao goriva: 48 % hrvatskog teritorija prekriveno je šumom [4]. Strategijom energetskog razvoja Republike Hrvatske do 2020. godine [5] određene su hrvatske strateške odrednice usmjerene na povećanje udjela obnovljivih izvora energije u neposrednoj potrošnji, pri čemu se jedan dio odnosi na korištenje biomase u energetske svrhe, odnosno određeno je da će se do 2020. godine koristiti 85 MWe iz biomase.…”

SažetakPotreba za energetskom neovisnošću s jedne te pritisci na okoliš s druge strane doveli su do povećane potražnje i ulaganja u obnovljive izvore energije. Europska unija je postavila cilj da udio obnovljivih izvora energije u ukupnoj energetskoj potrošnji bude 20 % do 2020. godine (Direktiva o korištenju obnovljivih izvora energije 2009/28/EC), odnosno 27 % do 2030. godine (Okvir za klimatsku i energetsku politiku u razdoblju 2020. -2030. godine). Povećanje korište-nja biomase kao obnovljivog izvora energije dovelo je do porasta količine pepela čija cijena odlaganja sve više raste. Stoga je potrebno osigurati njegovo održivo i učinkovito gospodarenje. Jedna od mogućnosti održivog gospodarenja pepelom jest njegova primjena u građevinskoj industriji. U radu je prikazana problematika gospodarenja pepelom iz drvne biomase (PDB), osvrt na karakterizaciju PDB-a, te preliminarni rezultati ispitivanja tlačne čvrstoće i čvrstoće na savijanje cementnih kompozita s različitim udjelima PDB-a kao zamjene za cement. Ključne riječi: obnovljivi izvor energije, drvna biomasa, pepeo iz drvne biomase, betonska industrija Use of wood biomass ash (WBA) as a cement replacement in concrete AbstractThe energy independence need and the concern of our environment has led to an increasing demand investment in renewable energy and their sources. Under Directive 2009/28/EC on the promotion of the use of energy from renewable sources, the European Union (EU) has set the goal to reach a 20 % renewable energy by the end of 2020. Moreover, within 2030 framework for climate and energy (COM/2014/015) agreed on EU´s long-term commitment target of at least 27 % for the share of renewable energy consumed in the EU in 2030. Consequently with increasing of combustion of biomass in the energy production, the amount of ash derived from biomass combustion is also increasing. These significant quantities of ash requires its sustainable management. One of possible solution for its management is utilization of wood biomass ash (WBA) in the construction industry. This paper describes problems regarding WBA management, review of WBA properties and preliminary results of testing mechanical properties (compressive and flexural strength) of cement composites made with WBA in different amounts per cement mass.

“…By burning biomass, large amounts of ash (the so called bioash) are produced that need to be adequately disposed of or recovered. It is assumed that the fulfilment of obligations imposed by Directive 2009/28/EC by 2020 will result in an annual production of 15.5 million tonnes of bioash in EU-28 [4], [5]. The resulting ash has to be recycled as its improper handling can cause environmental pollution and human health problems [6], while disposal at landfills reduces landfill capacity and leads to higher disposal costs [5,7,8].…”

Bioashes are inevitable product of meeting the demands to satisfy the increased use of renewable resources in energy production. Ecological and economic problems of bioash disposal, due to its appropriate chemical and physical properties, can be reduced by its application in the construction industry as raw materials. The paper therefore provides an research overview on various aspects of the bioash application in road construction, in compliance with a range of properties depending on the type of biomass and the conditions of combustion. Also shown is current state of research of bioash generated in the domestic thermal power plants.

The present study investigates the influence of partial cement substitution with biomass ash on the corrosion behaviour of steel embedded in the mortar. To evaluate this influence, corrosion parameters of steel in mortar exposed to tap water and 3.5 wt% NaCl solution were monitored over a period of 50 days.The electrochemical cell consisted of a steel plate as a working electrode, covered with a layer of mortar that was exposed to the testing solution.Open-circuit potential and linear polarisation were used to monitor changes in corrosion behaviour, whereas electrical impedance spectroscopy was used to evaluate the conductivity of the matrix. Additional to corrosion parameters, the chloride migration coefficient was tested after 28 days. On the basis of the results, it was observed that mortars with biomass ash provide equal or better protection for embedded steel, compared with the reference mortar. Mortars that performed slightly better than the reference mortar and other mortars were prepared with ashes with a higher amount of pozzolanic oxides.
