Field Test of Cement 

Field Test of Cement: Cement is the most important ingradient for construction work. It plays vital role because it is the binding material. So ensuring good cement in construction work 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.

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

7) Flexure Test: Make a 25 mm * 25 mm * 200 mm block if cement with water. Then immersed in water for 03 days. After removing, it is supported 150 mm apart and a weight of 15 kg uniformly placed over it. If it shows no sign of failure, the cement is good.
