Field Tests of Cement for Civil Engineers. Date of Manufacturing: As the strength of cement reduces with age, the date of manufacturing of cement bags should be checked. Cement Color: The color of cement should be uniform. It should be typical cement color i.e. gray color with a light greenish shade.

There are two main tests to be done on concrete: The SLUMP test. The SLUMP test shows the WORKABILITY of concrete. Workability measures how easy the concrete is to place, handle and compact. See CHAPTER 2 Concrete Properties The COMPRESSION test. The COMPRESSION test shows the best possible strength concrete can reach in perfect conditions.

Standard Test Method for Cement Content of Hardened Soil ...
It was developed primarily for testing samples for which a significant degree of cement hydration or hardening has taken place. Test Methods D 2901 or D 5982 may be used for determining cement content of freshly mixed soilcement mixtures. This test method is based on determination by chemical analysis of the calcium oxide (CaO) content of the sample.
