cold crushing strength property of cement

Modulus of Rupture an overview ScienceDirect Topics

MOR measures the bond strength of the test specimen. For castables, it measures the bonding strength of the cement matrix. The particle size and packing of the aggregate system are factors in MOR, but the maturity of the cement bond contributes more to MOR values. Cold Crushing Strength (psi, kg/cm 2)

Properties of Hardened Concrete; A Detailed Guide.

In practice, however, concrete with compressive Strength between 200-500 kg/sq.cm can be easily made on the site for the common type of construction. The compressive strength is also called the crushing strength, and it is determined by loading axially cube-shaped (or cylindrical shaped, in the USA) specimens made out of the concrete.

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.

Properties of concrete Wikipedia

Concrete has relatively high compressive strength (it doesn't crack under weight), but significantly lower tensile strength (it cracks when being pulled). The compressive strength is typically controlled with the ratio of water to cement when forming the concrete, and tensile strength is increased by additives, typically steel, to create reinforced concrete.
