This paper deals with a development of inorganic materials combined with pulverized waste gypsum board and by - products . 3 kinds of components were treated in this study; fly ash (F) , ground granulated blast furnace slag (GGBFS :S) and pulverized gypsum (G) . The fundamental properties of F-S-G paste regarding fluidity , compressive strength and drying shrinkage strain were tested and the influence of replacement ratio of pulverized waste gypsum board (PWG) was investigated . The test results showed that F-S-G with high content of GGBFS exhibited higher compressive strength and the replacement ratio of PWG significantly decreased the strength . In this study, the recovery technique for the decreased compressive strength was also conducted .
