Utility Assessment of Biomass Fly-Ash for Production of Concrete Products


Zitieren

International agreements oblige our state to develop ecological sources of energy, one of which is biomass. During its combustion fly-ashes are produced. Several studies have shown that they might be useful in concrete production. The article presents a comparison of biomass fly-ash and coal fly-ash influence on the properties of cement composites. The replacement levels of cement by fly-ash (FA) were 20%, 40% and 60%. Biomass fly-ash FA(B) have replaced coal fly-ash by 0%, 50% and 100%. The compressive strength tests showed similarities in strength development of coal and biomass fly-ashes concretes. Specimens with biomass fly-ash presented similar or better abrasion resistance comparing to coal fly-ash samples.
