Portland cement - Wikipedia

Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout.It was developed from other types of hydraulic lime in England in the late 19th century by Joseph Aspdin, and usually originates from limestone.It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker ...

Effects of Cement Particle Size Distribution on ...

Thus, there are two conflicting effects of cement fineness on autogenous shrinkage. On the one hand, a finer cement results in a greater RH reduction, resulting in higher values of the capillary stress. On the other hand, as illustrated in Table II, the amount of water-filled porosity may be less in the finer cement paste due to its higher ...

Fineness - an overview | ScienceDirect Topics

6.3.3.1 Cement Fineness. The fineness of cement is a major factor influencing its rate of hydration since the reactions involved occur at its interface with water. Ordinary Portland cement (Types I and II) has a surface area between 3000 and 3500 cm 2 /g, while the surface area for rapid hardening Portland cement (Type III) ranges from 4000 to ...

Cement: Fineness Test

Cement: Fineness Test . The degree of fineness of cement is the measure of the mean size of the grains in it. There are three methods for testing fineness: the sieve method-using 90 micron (9 No.) sieve, the air permeability method-Nurse and Blains method and the sedimentation method-Wagner turbidimeter method. The last two methods measure the surface area, whereas the first measures .

Cement Fineness| Concrete Construction Magazine

The fineness of cement influences the drying shrinkage of concrete. When the water content is increased because of fineness, the drying shrinkage is increased. However, if excessive bleeding due to coarseness of the cement takes place, a reduction in the drying shrinkage occurs. 8. The resistance of air-entrained concrete to deterioration ...

Fineness of cement particles may be determined either by sieve test or by permeability apparatus test. In sieve test, the cement weighing 100 gm is taken and it is continuously passed for 15 minutes through standard BIS sieve no. 9. The residue is then weighed and this weight should not be more than 10 per cent of original weight.
