he thermal shrinking mechanism of high shrinking PP fiber and change of the super molecular structure in the shrinking process was studied by means of wide angle X ray diffraction and micropolariscope.

It is a hot field that the research of improving fire-resisting perpormance of HPC through incorporating polypropylene fiber(PP fiber) or steel fiber.

Through the testing on relative cracking index and energy at break,the effect of silane coupling agent modification on the plastic shrinkage cracking resistance of PP fiber in cement mortar was also investigated.
