Investigation on effect of nano gel wollastonite on properties usage of wood-cement composites manufactured from rice straw fibers

In this study the effect of nano gel wollastonite usage in three level (0 , 5 and 10 percent per dry by weight of the cement) and the mixture ratios of lingocellulosic material to cement in three level 10:90, 20:80 and 30:70 on physical, mechanical , microscopic and biological properties of composit...
