Abstract:

Clinker was produced by Simulating cement calcination test,and concrete samples were also prepared according to national standard GB/T 17671-1999.Long-term cumulative release amount of heavy metals in cement product from co-processing waste in cement kiln was researched through leaching test which refers to EA NEN 7371 and EA NEN7375,and one-dimensional diffusion model which is on the base of Fick diffusion law.The results show that availabilities of heavy metals are lower than the total amounts in concrete...
