Abstract

Abstract

In this paper the effect of Fe(OH)₃ on the improvement of mechanical properties of titanium gypsum through addition gypsum enhancer had been investigated.The experimental results indicate that the effect of gypsum enhancer on improving the mechanical properties of titanium gypsum is significantly reduced with the increasing ratio of Fe(OH)₃.Hence,in order to reduce Fe(OH)₃ content,part of titanium gypsum is replaced with relatively pure desulfurized gypsum without Fe(OH)₃.It is seen that the mechanical properties of titanium gypsum are improved greatly with the increasing ratio of the new gypsum enhancer.The optimized gypsum enhancer content ranges 0.07%~0.11%.When the gypsum enhancer content reached 0.09%,the flexural strength and compressive strength of titanium gypsum after 2 h curing will increase 18% and 25% respectively,compared with those of without addition of gypsum enhancer.These strength meet the requirements for grade 1.6 of "Building Gypsum"(GB/T 9776-2008).
