Field Test of Cement 

Field Test of Cement: Cement is the most important ingredient for construction work. It plays a vital role because it is the binding material. So to ensure excellent quality of cement in construction work, it is important to know the field test of cement.

Here we will discuss about the the field test of cement:

1) Manufacturing Date:
 As strength of cement reduced with time, so checking of manufacturing date is very important. 

2) Colour of Cement: Colour of cement should be uniform and it would be light greenish gray.

3) Presence of Hard Lump: Presence of lump in cement bag indicates the moisture absorption. So it should be free from lump.

4) Temperature: Temperature of cement in bag is very important. Normally if someone enter his hand in a cement bag it will feel cool. But if it feel worm, ( but new cement from the manufacturing will be warm) then it indicate that hydration reaction start there, which is not desired. 

5) Smoothness: When cement rubbed with two fingers it will feel smooth. Rough in feelings indicate adulteration.

6) Water Sinking:  If a small quantity of cement thrown on water in-case of good quality cement it will sink.

Performing these field test you can confirm good quality cement at your construction field.
