The Study On The Solidification Of Waste In Cement And The Infusion Of Harmful Metal Ion

In order to inspect the cement in the use of waste, the influence of cement performance, the solidification degree of harmful metallic ion, as well as the microscopic structurechange in the use process, Mixxing the certain proportion the fly ash, the slag, rubbish burn ash, construction trash, the building materials waste material, the battery waste residue, the galvanization sludge, the city sewage river bottom putty, the sewage treatment plant sludge and so on in cementunitary or compound , to take cement mechanics performance examination, the harmful ion leaching examination as well as the different hydrated time microstructure observation and so on a series of experiments. Chose simulating the real condition as far as possible the leachingtesting method. The result indicated that, in the cement mixing the suitable proportion waste, unitary or compound, the cement performance does not receive affects, even has the improvement, The harmful metallic ion leaching is lower than the national standard, namely the cement use compound waste has the certain feasibility and the necessity, Not only has used waste, reduced the cost, more over has protectedthe environment, has the important social significance.
