abstract / sažetak
According to the principles of the circular economy, there is great potential for developing synergies between the construction and energy sectors through the use of by-products from other industries or recycled materials in the concrete industry. The objective of this study is to determine the potential of using locally available wood biomass ash (WBA) as a partial substitute for fine aggregate (sand) in concrete. This paper presents the influence of WBA on the relevant mechanical properties and durability of precast concrete, where a part of fine aggregate (sand) was replaced by different types of WBA in a proportion of 15%, and its influence was investigated in relation to the prescribed requirements of precast manufacturers.
Prema načelima kružne ekonomije postoji veliki potencijal razvoja sinergije između građevinskog i energetskog sektora kroz upotrebu nusproizvoda iz drugih industrija ili recikliranih materijala u betonskoj industriji. Cilj je ovog istraživanja pronaći mogućnosti uporabe lokalno dostupnog pepela drvne biomase (PDB) kao djelomične zamjene za sitni agregat (pijesak) u betonu. U radu je prikazan utjecaj PDB-a na relevantna mehanička svojstva i svojstva trajnosti lijevanog betona u kojima je dio sitnog agregata (pijeska) zamijenjen s različitim vrstama PDB-a u udjelu od 15 % te je proučavan njihov utjecaj u odnosu na propisane zahtjeve proizvođača predgotovljenih elemenata.
