| Abstract: | In this paper,characteristics and dry process of river silt from Shanghai Jinshan District was studied,and sintered porous brick with substitution of 100% river silt for clay raw material was industrialization produced.The properties of river silt sintered porous brick such as appearance,physical mechanics and environmental safety were discussed systematically.The results indicate that,river slit is a kind of clay material with main chemical component of SiO2.River silt sintered porous brick with strength grade above MU20 can be produced by reasonable mixture proportion and production process,and each technical index reaches or exceeds the requirement stipulated in national standards. |
