Web1 dag geleden · This shows that with increasing curing time, the AAS concrete is further hydrated, the internal pore content is reduced, and the concrete is more compact. With the increase in LS content, the D nssm of AAS-LS concrete is lower than that of pure slag concrete. When the limestone content is 10%, the D nssm of L10S cured for 28 d and … WebHydrogarnet forms mainly as the result of C 4 AF or C 3 A hydration. Hydrogarnets have a range of compositions, of which C 3 AH 6 is the most common phase forming from normal cement hydration and then only in small amounts.
