pore size distributions were measured by mercury intrusion porosimetry (MIP, Poremaster-60, contact angle 140.7°) with an operating pressure up to about 500 MPa. Hydration products of hardened cement pastes X-ray diffraction

Specific surface area, pore volume and pore size distribution of the catalyst were obtained from the N 2 adsorption–desorption measurements on a Quantachrome NOVA-2200e automated gas sorption system. The samples were pretreated in vacuum at 200 °C for 12 h

compressive strength for high-performance concretes and mortars up to 28 days [ 18 , 23 ]. The critical factor affecting the performance of concrete structure is pore structure development—pore size distribution rather than the total porosity. The
