adsorption and desorption techniques. The pore-size distributions of precursors and phosphors are compared in Fig. 4 . It is obvious that, the thermal treatment leads to a significant increase of pore diameter together with decrease of their volume. Powder

. Such materials are characterized by high specific surface area and well developed porous structure with ordered framework and narrow pore size distribution. The structure of mesoporous materials allows using them as host materials, catalyst for

mA). Nitrogen physisorption measurements were carried out at 77 K using Quantachrome NOVA Automated Gas Sorption Instrument. The pore-size distributions were calculated from the desorption isotherms with the BJH method. The

. However, one shortcoming has not been solved perfectly, that is relatively low early strength of blended cements [ 2 ]. It is generally accepted that the properties of hardened cement paste are closely related to its porosity and pore size
