文摘The hydrating products and microstructure of permeability resisting portland cement have been studied by x-ray diffraction (XRD) and electron microscopy (EM). The hydrates such as calcium silicates hydrate and calcium sulphaluminate hydrate, ettringite crystal of needles can be observed under the EM, most of which were filled into pores of hardened cement paste.
