Abstract Bottom ash from EC Gdańsk and dredged material taken from the mouth of The Vistula were mixed to form an engineering material used for dike construction. Mixtures with different bottom ash content were tested in laboratory to determine its basic physical and mechanical properties. The optimum bottom ash-dredged material mixture, built in the corps of the test dike, contains 70% of ash. The optimum bottom ash content in the mixture was chosen taking into account high internal friction angle, good compaction and reduced filtration coefficient. The maximum dry density of the mixtures was measured in Proctor test for the mixtures formed in laboratory and on samples taken from the test dike. Minimum and maximum void ratio were also determined.

Solid Waste Incinerator

In the European Union, more than 140 million tonnes of municipal solid waste is incinerated annually. It generates about 30–40 million tonnes of residues known as municipal solid waste incinerator bottom ash, which is typically landfilled. To deal with growing landfills, there is a need to utilize municipal solid waste incinerator bottom ash as a building material. It has been known that municipal solid waste incinerator bottom ash properties strongly depend on waste composition, which is directly influenced by people’s habits, economic policy, and technologies for metals recovery of bottom ash. Thus, municipal solid waste incinerator bottom ash produced in a specific country or region has primarily to be tested to determine its physical and mechanical properties. The main aim of this study is to determine municipal solid waste incinerator bottom ash physical and mechanical properties (aggregate particle size distribution, water content, oven-dried particle density, loose bulk density, Proctor density, optimal water content, California Bearing Ratio after and before soaking, permeability, Flakiness Index, Shape Index, percentage of crushed and broken surfaces, resistance to fragmentation (Los Angeles coefficient), water absorption and resistance to freezing and thawing). Municipal solid waste in-cinerator bottom ash produced in the waste-to-energy plant in Klaipėda (Lithuania) was used in this research. Ferrous and non-ferrous metals were separated after more than three months of municipal solid waste incinerator bottom ash ageing in the atmosphere. The study showed promising results from considering municipal solid waste incinerator bottom ash as possible aggregates for road building materials.

In this article, the influence of the addition of the bottom ash to clay on the selected physical and mechanical properties of ceramic composite are discussed. The biomass (80% wood with the addition of 20% coconut shells) was combustion in the fluidised-bed boiler. The tests were carried out on the samples, in which the contents of bottom ash in relation to clay ranged from 5 to 15%. The absorbability, open porosity, apparent density, compression strength and freeze resistance have been determined. The obtained test results indicate that the increase of this bottom ash in clay-ash composite causes the increase of open porosity, absorbability and compression strength, but a reduction in resistance against frost attract.

Bottom ash has been presented as a major problem of disposal throughout the world, since it is produced from the process of coal combustion in thermal power plants. However, its physical and chemical properties make the bottom ash an adequate potential construction material in variety of applications.The aim of the study was to investigate the possibility of utilization of bottom ash for production of ceramics compacts and to analyse the influence of the main process parameters and their interaction on the physical and mechanical properties of the final product. Consolidation of the powders was conducted on two bottom ash samples with particle size (S) -0.250+0.125 mm and -0.500+0.250 mm, pressing pressure (P) of 100 and 150 MPa and sintering temperature (T) of 1100 and 1150 oC. The density (r) and bending strength (s) of the dense bottom ash compacts were the response function. The optimization was performed through implementation of main effect plots, Pareto charts and 3D surface method using “Statgraphics Centurion” software package. The obtained model equations of the density and bending strength dependence from the main process parameters are solid basic data for modeling the process of ceramic production.

The clay-based ceramic was produced by adding with the bottom ash from domestic municipal solid waste incinerator plant in Thailand. The amount of the ash up to 60 wt% was added. The samples were dry pressed and sintered at the temperature range between 1000 and 1125°C. The presence of quartz (SiO2), anorthite sodian (Ca,Na)(Si,Al)4O8, albite (Na(Si3Al)O8) and mullite (Al6Si2O13) was observed in the sample with the addition of the bottom ash. The physical and mechanical properties were also presented. The sintering temperature and the ash addition revealed the effect on the properties of the product.

Tanjung Bin is one of the biggest coal-fired power plants in Malaysia to generate electricity. The by product from burning of the coal ash produce 42, 000 metric tons of fly ash and 8, 000 metric tons of bottom ash every month. This huge amount of waste requires large area for disposal storage and also may cause environmental problems. This paper aims to study the properties of bottom ash and the possibility to be used as a substitute materials of sands. The laboratory testing program covered physical and mechanical properties of bottom ash. The physical testing includes specific gravity and particle size distribution, whereas, the mechanical properties are Standard Proctor compaction, relative density, permeability and direct shear test. The results show that the properties of bottom ash have similarities to those of sand thus there is a potential to be used as sand replacement materials in construction and engineering works.
