Research on mixing ratio of waste mud brick

In order to achieve green building materials, energy conservation, waste reuse purposes. Use city sewage sludge as part of the raw materials for production of shale brick is studied by experiments adopted the different mixing ratio, find matching and the relationship between the compressive strength. Experimental results show that the shale powder to add quality percentage is 40% of dry sludge, formed a burning brick, brick of various performance accord with national standards, not only can save coal and mineral resources, improve the heat insulation brick, but also a lot of recycling of utilization of sludge.
