Compressive Strength

PCC is most often known by its compressive strength. This is because PCC is much stronger in compression than...
Early Age Behavior

The service life of PCC pavements is highly dependent upon their early-age behavior. Rigid pavements are significantly affected by...
Portland Cement Compressive Strength

The most common strength test, compressive strength, is carried out on a 50 mm (2-inch) cement mortar test specimen....
Portland Cement Fineness

Fineness, or particle size of portland cement affects hydration rate and thus the rate of strength gain. The smaller...
Portland Cement Flexural Strength

Flexural strength (sometimes called the modulus of rupture) is actually a measure of tensile strength in bending. PCC flexural...
Portland Cement Loss on Ignition

Loss on ignition is calculated by heating up a cement sample to 900 - 1000°C (1650 - 1830°F) until...
Portland Cement Setting Time

Cement paste setting time is affected by a number of items including: cement fineness, water-cement ratio, chemical content (especially...
Portland Cement Soundness

When referring to portland cement, "soundness" refers to the ability of a hardened cement paste to retain its volume...
Portland Cement Specific Gravity

Specific gravity is normally used in mixture proportioning calculations. The specific gravity of portland cement is generally around 3.15...
Portland Cement Tensile Strength

Although PCC is not nearly as strong in tension as it is in compression, PCC tensile strength is important...
