Abstract
Properties of Self-compacting Concrete Produced with Biomass Wood Ash
Highlights
Considering the progressive pollution of the environment and shortage of fossil fuels, there is a tendency in the contemporary society to maximize the use of renewable energy sources [1]
The paper presents the research of potential use of biomass wood ash as a partial replacement for coal fly ash (10%, 20%, 30% and 40% of mass) in production of self-compacting concrete (SCC)
Test results indicated that the biomass wood ash slightly reduces the flowability and passing ability of SCC, while its addition enhances the viscosity of SCC and significantly prevents segregation and bleeding
Summary
Considering the progressive pollution of the environment and shortage of fossil fuels, there is a tendency in the contemporary society to maximize the use of renewable energy sources [1]. Wood biomass is considered as a carbon neutral fuel as it absorbs the same amount of carbon dioxide while growing as released by burning it [2]. These are the reasons why the number of bioelectric power plants is increasing. Most of the ash is deposited in landfills, and a smaller portion is used as an addition to soil in agriculture or for various other uses [3,4]. Landfill disposed ash poses a risk to the environment due to the possibility of air and groundwater contamination and must be properly managed
