Effect of Fly Ash Content on Properties of Fly Ash-Coal Gangue Foam Concrete

Abstract:

Article Preview

The effect of the fly ash content on the properties of the fly ash-coal gangue foam concrete was studied in this paper. Results revealed that: With the increase of the fly ash content, the dry density, the compressive strength and the shrinkage of the fly ash-coal gangue foam concrete decrease; the density of the fly ash - coal gangue foam concrete was influenced greatly by the ratio of water to total dry material. The pore structure and microstructure of the foam concrete was analyzed by scanning electron microscopy, and the results show that most of the pores are fine, closed, and even distributed.
