“…14-15% (typically around 5-8% for natural aggregates [22]). Optimum moisture contents are also in line with those reported by other authors [1,[18][19][20]25]. The fact that Proctor curves show a well-defined maximum suggests that maximum dry densities are markedly sensitive to water content.…”

“…Five different major components may be distinguished in the fractions (2-25 mm) of bottom, namely slagged material, relict metal, relict domestic glass, ceramics/synthetics and unburnt matter, as identified in other studies [2,18]. Their particle size distribution shows similar trends among samples and therefore in Fig.…”

This should not be attributed to poor compaction but it is rather linked to the lower particle density of bottom ash [2].…”

“…The construction of roads requires lots of materials, one of which is sand or cement bases. Incineration ash is technically feasible for road construction and can serve as an alternative to sand and cement bases and sub-base [196], but the presence of heavy metals poses a threat to soil and underground water. The use of incineration ash as a raw material for the construction of roads serves two goals: firstly, it reduces the consumption of natural resources; secondly, it is a successful step towards "zero landfill" [197].…”

Incineration Fly Ash and Its Treatment to Possible Utilization: A Review

2020

Incineration has gained popularity over landfill as a key solution for the reduction of massively increasing volumes of municipal solid waste (MSW) generation worldwide and in particular China. However, it is not the end solution. The disposal of the incineration residues, which are enriched with a wide range of heavy metals and soluble salts, has become a challenge for the environmental managers. The aim of this study was to review the increasing urbanization and its repercussion on waste generation in China; waste management options were compared for possible environmentally friendly considerations. Treatment techniques of incineration fly ash were discussed to determine the effectiveness of obtaining environmentally stable material, and, finally, possible applications of incineration fly ash for utilization were discussed based on identifying the processing suitability, performance and environmental impact of incineration fly ash for its applications.

“…In Germany and France, the recycling rate of bottom ash was more than 60%, and in Denmark and Holland, this rate even reached 80% [12], while in China, the recycling rate of bottom ash is still low [19]. e municipal solid waste incineration bottom ash is widely used as soil improvement materials, concrete aggregate, and roadbed stuffing [16,[20][21][22][23][24]. In China, bottom ash is mainly used as concrete aggregate, supplementary cementitious material [25,26].…”

As a by-product from the incineration of municipal solid waste, bottom ash has a broad application prospect of resource utilization. In this study, bottom ash was selected as partial aggregate alternative and used as roadbase materials. The cemented aggregate containing bottom ash was evaluated through both experimental and numerical analysis. According to the results, the unconfined compressive strength of samples increases with the curing time, and the failure strain of sample decreases with the curing time. The unconfined compressive strength and failure strain of samples are influenced by the types of bottom ash. The increase of compressive strength with the curing time can be attributed to that the hydration reaction of cement will be more complete when the curing time is longer. The representative value (7 days) of unconfined compressive strength of samples meets the strength requirement (≥2.5 MPa) of the road subbase layer of heavy traffic highway in China. Subsequently, the surface settlement decreases with the increase of the modulus and thickness of roadbase and the distance from the centerline, while the settlement increases with vehicle load increasing. The modulus of the roadbase is not the main influences on the pavement settlement, under the condition that the strength of samples meets the requirements. However, increasing the thickness of roadbase can reduce the settlement at the center of the pavement effectively.
