Fineness of Cement – Definition – Test

Fineness of Cement – Definition – Test · Fineness of cement is another quality control parameter that experts keep in check of at the laboratory. The size of the particles of OPC impact the surface area and the heat of hydration. I've already explained the definition in my previous article on different physical properties of cement. So, if would reproduce my answer to ...

Cement: Fineness Test

Cement: Fineness TestCement: 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 methodusing 90 micron (9 No.) sieve, the air permeability methodNurse and Blains method and the sedimentation methodWagner turbidimeter method. The last two methods measure the surface area, whereas the first measures .

Lecture No. : 4

Lecture No. : 4 Finer cement exhibits a higher shrinkage and a greater proneness to cracking. An increase in fineness increases the amount of gypsum required for proper retardation because, in finer cement, more C 3 A is available for early hydration (due to the increase of its surface area). Fineness of cement is tested in two ways: (a) By sieving.

What is the significance of Fineness of Cement?

What is the significance of Fineness of Cement? · Collect a sample of cement and rub with your hands. The Fineness test sample should be free of lumps. Take 100 gm of cement sample and note its weight as; Drop 100 gm of cement in 90 µm sieve and close it with the lid. Now, shake the sieve by agitating the sieve in planetary and linear movements for 15 minutes. After that take weight the retained cement on the 90 µm sieve as; Fineness .
