Abstract
The preliminary results of utilization of bottom ash from combustion of biomass for the produce of concrete has been presented. Currently, this waste are deposited in industrial waste landfills. The chemical composition of waste materials was determined using X-ray fluorescence (spectrometer ARL Advant 'XP). Concrete were made using CEM I 42.5 R (Cemex) and sand - gravel mix aggregate. The obtained concrete were subjected to microscopic examination (LEO Electron Microscopy Ltd.) and their compressive strength (PN-EN-196-1) and absorbability (PN-85/B-04500) were identified. The obtained results showed, the replacement of the natural aggregates by bottom ash from combustion of biomass reduce consumption of raw materials and will have a good influence on the environment.
