Renewables-based power grid expansion has increased the use of wood biomass as a low-carbon fuel, resulting in the generation of predominantly inorganic wood biomass ash (WBA) as waste during biomass combustion. The conservation of historically valua

Pozzolanic activity of materials can initially be assumed from the quantity of the pozzolanic oxides SiO2, Al2O3 and Fe2O3. Some of the methods for assessing pozzolanic reactivity of materials include measurement of CaO consumption (Frattini test), d

Wood biomass is widely used in the European Union as a fuel for the production of heat and electrical energy, generating a considerable amount of ash. The disposal of ash, especially its finest fraction, requires proper engineering solutions, since t

The trend of wood biomass use as a renewable energy source has contributed to an increase in the quantity of wood biomass ash (WBA) that is regarded as waste. Currently, 70 % of WBA is landfilled, 20 % is used in agriculture, and 10 % is used for oth

Self-compacting concrete requires a special composition with an increased proportion of fine particles and larger volumes of paste compared to traditional vibrated concrete. Larger volumes of paste increase autogenous deformation, which can cause mic

Different types of fibres are often used in concrete to prevent microcracking due to shrinkage, and polypropylene fibres are among the most often used ones. If not prevented, microcracks can lead to the development of larger cracks as drying shrinkag

The potential for using sewage sludge ash (SSA) in cement mortars and concrete is reviewed. The chemical and physical properties and pozzolanic activity of a range of different incinerated SSA samples indicates the potential to exploit the pozzolanic
