/Hβ-c N 2 adsorption–desorption isotherm, pore size distribution and pore volume Fig. 3a presents the N 2 adsorption–desorption isotherms for the three catalysts. It can be seen that the steep rise started from P/P 0 = 0 and the

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

drying and wetting cycles, hydration time, and the type of water binding [ 10 ]. The quality of studied organic material and its pore size distribution plays a significant role in hydration kinetics as well [ 12 ]. After the absorption of water, size of

. 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
