The finer particle size of fly ash may propose a denser structure with thorough mixing condition between the cement hydration product and the asphalt membrane. Based on the mixing stability test results, the residue content of the cement mixture is higher than that of the fly ash mixture (FA30), and this may form bigger particle size .
Many cement labs have switched to using laser diffraction to measure the particle size of their cement. This technology is fast, easy to use, flexible, and repeatable. HORIBA offers two laser diffraction analyzers to the cement .
Particle size and shape are two of the most important physical properties of particulate samples. Even small differences can significantly affect material properties such as chemical reactivity, bioavailability, dissolution and crystallization rates, stability .
The same effect is observed when introducing fine glass particles having a similar size as cement particles in a cement paste or concrete. 12 The substitution of a part of the cement by glass particles increases the compressive strength of a UHSC by 20% because of the strengthening effect of the hard and rigid glass particles as seen in Fig. A and B.
