Paper Title:
Research on Mechanical Properties of Molded Products Using Building Waste
  Abstract

Recycle utilization of building waste is the tendency of building material for environment protection & sustainable development. Mechanical properties of molded products using building waste (MPBW) were investigated. The main parameters are focus on molded pressure, dosage of building waste added into cement and fly ash. The results of experiments showed that molded products using concretes debris as fine aggregates have stronger mechanical properties. The strength of product increased along with molding pressure increase under 15MPa , but it was almost no increase when the molding pressure was up from 15MPa to 20MPa.The addition of building waste has little effect on the compressive strength of product when its dosage range from 50% to 100% .The strength of product had obviously changed after using fly ash partially substitute for cement, when fly ash replace two thirds cement, the product strength of 28d was 15.4MPa, and was still higher than that of the normal wall materials. Later strength of the product had markedly increased, its 180d compressive strength achieved 25.2MPa. Test results confirmed: using building waste, panel, block and other products with better mechanical properties could be manufactured by adjusting the molded pressure and the dosage of building waste and fly ash.
