Abstract

Quick hardened property and compressive strength experimented to the C4A3 quantities. Workability experimented to the hydration behavior as retarder added to the C4A3. Compressive strength reached {{{{ delta }}3h=300~350 kgf/$\textrm{cm}^2$, {{{{ delta }}6h=400~450 kgf/$\textrm{cm}^2$, {{{{ delta }}24h=500~550 kgf/$\textrm{cm}^2$. Flow loss rate reached 70.1% to retarder addition 0.12% after 15 min. Test items were SEM, XRD, TG-DTA, MCC, porosity and zeta potential.
