Effects on Cold Modulus of Rupture and Cold Crushing

Cement addition, water addition and wet curing period are selected as the effects on cold modulus of rupture and cold crushing strength of one LCRC. According to the molding morphologies of the castables, when the water addition is 8 wt. %, the castable is suitable to be cast by vibration fashion, and the high strength of the castable can be kept because the hardening time is not very long.
