| Cement |
Following are some field tests, that should be carried out to know the quality of cement.
1. Date of packing:
It should be within 3 months at the time of purchase.

2. Lumps test:
It should be free from any lumps which might be formed due to atmospheric moisture.
3. Colour test:
Cement should be of uniform grey color, with a light green shade.
4. Float test:
When little quantity of cement is poured into a bucket of water, some part of it should float on the water for a few seconds, forming pockets before sinking.
5. Setting test:
A thick paste of cement should be applied evenly over the piece of glass. After an initial setting time of 30 minutes, it should be kept in water for 24 hours.
The next day, when you test the cement, it should be hard in a single piece, if it breaks into several pieces then the cement is not of good quality.
6. Adulteration test:
When cement is rubbed between two fingers, you should get the smooth feeling of fine powders. If you feel the rough grainy texture, then there is a possibility of adulteration.
7. Temperature test:
When kept over the palm, you should feel the normal atmospheric heat. It should not be much warmer.
