Field test for cement are reliability checks on concrete were carried out to know the quality of the supplied cement within a short period of time. Laboratory tests can not be conducted in a short time, so in these periods the simple field tests of cement are done on the cement to verify its performance. Such measurements give some idea of the cement’s value.

Tests on Cement at a Construction site:
- Color test

- Adulteration test
- Temperature test

- Strength test
- Setting test
- Date of packing
Color Test of Cement
The standard cement color should be gray with a light greenish edge. It should be uniform in color.
Presence of Lumps
Cement produces lumps because of the atmosphere’s humidity. But using that for a building isn’t great. Any bag that is supplied with lumps to the site should be discarded.
Adulteration Test
This test is done by fingering the concrete. Once rubbed between the fingertips, it should feel smooth. If it feels rough, it means adulterating the cement with sand.
Temperature Test of Cement
To check its temperature, this test involves putting the hand into the container. It ought to be hot inside. When the inside is cold, it means that the hydration process is taking place. Read More
Float Test
This test involves tossing a pinch of concrete into the water-filled tub. Before sinking, the cement particles should float for a while.
Setting Test
In this experiment, by combining cement and water, a thick paste is prepared and placed on a piece of the glass plate. This is held 24hours underwater. It should be mounted and not broken after that.
Strength of Cement Test
This test involves preparing a 25 mm ×25 mm cement block with a length of 200 mm. It’s immersed in water for seven days. It is then mounted 150 mm apart on supports and packed with a weight of approximately 34 kg. If there is no defect in the block, then the cement is of good quality.
Date of Packing
Cement strength decreases over time, so it is important to check the cement production date. In particular, the cement should be used within 90 days of the date of manufacture.
