An Experiment and Disscussion on the Mineral Composition of Portland Cement for High Way

Zhu Ming Qiu Shuheng Wen Jin (1 Inst.of Mater.Sci.& Eng.Wuhan Univ.of Tech.Wuhan,430070; 2 College of Chemistry and Chemical Engineering,Guangxi Univ.Nanning,530004)  
This paper, Studies the wearability of C 2S,C 4AF and the low KH(0 87) high ferrite cement blended with composite mineralizers CaF 2+CaSO 4(or BaSO 4). The result indicates that C 2S possesses excellent wearability.It also demonstrates that when compressive strength exceeds certain value,futher improvement of wearability is associated much less with the increase of the compressive strength.
