Abstract: |
Fast setting of AAS (alkali activated slag) cement is the biggest
obstacle for them to be used in practical engineering. The setting property and strength
development of AAS cement were investigated with respect to the fineness of slag, main
parameter of activator, the concentration of effective composition as well as the kind and
incorporation of retarder. The mechanism of fast setting of AAS cement was analysed by means
of hydration heat test, nonevaporable water measurement and mercury intrusion porosimetry.
Based upon the test results, the technique of controlling the fast setting of AAS cement
effectively is discussed. |
