“…Extracted organic wood components, in particular beech, have a high amount of water-soluble sugars and therefore, reveal an inhibiting effect on the cement hydration, resulting in a retarded reaction time, having a reduced maximum hydration temperature (Wei et al 2000b) and a lower strength of hardened cement paste (Schubert et al 1990a). Research in the field of wood/cement interaction has shown that cement composition (e.g., use of low-alkali cements), usage of cement admixtures (e.g., chemical cement setting accelerators) and pre-treatment of wood (e.g., steaming, hydro extraction, sodium hydroxide extraction or cement micro coating) help to compensate the abovementioned cement hydration inhibiting effect (Klatt 2012;Schubert et al 1990aSchubert et al , 1990bSchwarz and Simatupang 1984;Simatupang 1986;Wei et al 2000a).…”
