The Study of Properties for Quick Cement Mortar Grouts

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.

Key words: Quick hardened cement mortar grouts, Retarder, Anhydrite
