摘要: Abstract Solidification and stabilization of coal bottom ash waste (CBA) using CEM1 as the binder have been evaluated in case leaching well possibility to use this mixture for construction industry. For this, CEM1/CBA mass ratio has varied between 0.5 2 heavy metals Cu, Cd, Ni Pb evaluated. Two types crushed block whole tests conducted determine properties deionized water, acetic acid nitric leachates. It demonstrated that all elements can be immobilized successfully nearly zero even a low content. Furthermore, it shown more leached from matrix when used compared other Next mechanical tested. After 56 days compressive strength 25 40 MPa measured ratios. Based on results, mixtures considered
