Co-combustion of rice husk and sewage sludge. The hydration is dominated by NG initially and then dominated by D. The novel cementitious material yields excellent mechanical properties. Leaching toxicity tests show the blended cement is environmentally acceptable. F-T action has negative impact on the leaching of HMs in the novel material systems.
