The performance of industrial waste incineration bottom ash and quarry dust in controlled low-strength material (CLSM) is investigated and presented in this work. The experimental investigation was carried out in two phases; preliminary and detailed. The preliminary investigation was aimed at finding the feasibility of industrial waste incineration bottom ash in CLSM application and to study the effect of refined kaolin as an additive on the performance of CLSM. Results indicated good potential for the use of bottom ash in CLSM, the addition of refined kaolin reduced the strength, but...
