• Small cylinders endure longer lives under fatigue loading. The maximum pore size is larger in taller cylinders, which conditions their lower performance. A wall effect induces an inverse monotonic static effect. Cylinders fewer cycles than cubes of comparable size. law Sparks and Menzies insensitive to cylinder This study deals with the influence fiber concrete mesostructure on compressive Fo...

a series of fe3o4 supported on mesoporous fdu-12 silica systems were prepared by the hydrothermal conditions. the surface properties of the functionalized catalyst were analyzed by a series of characterization techniques like ftir, xrd, n2 adsorption–desorption and tem. xrd and adsorption–desorption analysis shows that the mesostructure of fdu silica remains intact after fe3o4 modifications, wh...
