Preliminary Research on Waste Incineration Bottom Ash Concrete

Abstract:

Article Preview

We use the bottom ash from Harbin Municipal Solid Waste Incineration Plant as concrete coarse aggregate and study the engineering properties of the coarse aggregate, failure mode of waste incineration bottom ash concrete, the relationship between compressive strength and bottom ash coarse aggregate replacement rate, water cement ratio, apparent density and development trend of compressive strength. Comparing with natural aggregates, the bottom ash has higher water absorption rate, lower apparent density and crushing value index. The failure mode of waste incineration bottom ash concrete is similar to ordinary concrete and the flat and elongated particles have effect on compressive strength. Bottom ash coarse aggregate replacement rate has different effects on compressive strength in different water cement ratio. Compressive strength of waste incineration bottom ash concrete has the same development trend with ordinary concrete. Compressive strength and apparent density has a linear relation.
