Stabilization of urban waste incineration ash and coal fly-ash

A guarantee against the industrial waste disposal site has become so difficult that the treatment problem of waste assumed seriousness. Accordingly, a block plate was produced by use of a new cement hydration accelerator developed as a method for the solidification of incineration ash and coal fly-ash and the effective utilization of industrial waste, and then was evaluated by the uniaxial compressive strength test. When the kind and the mix proportion of accelerators were properly selected corresponding to the stabilization materials, it was confirmed in the range of experiment, that the cement hydration accelerators contribute to the acceleration of hardening
