Possible errors in cement testing can arise from improper sample preparation, such as inadequate mixing or incorrect water-to-cement ratios, which can affect the consistency and strength of the mixture. Contamination of samples or equipment can introduce foreign materials that skew results. Additionally, inaccurate measurement of time during tests, environmental factors like humidity and temperature, and human errors in recording data can also lead to discrepancies in the test outcomes. Proper calibration of equipment and adherence to standardized testing protocols are essential to minimize these errors.
For Testing of soundness of cement.
Cement paste is formed when cement is mixed with water. However, cement mortar is formed when cement is mixed with fine aggregate (sand) and water.The strength of cement mortar is more when compared to cement paste.Shrinkage will be less in cement mortar and high in cement paste.

For Testing of soundness of cement.
Cement fineness: Finer cement particles generally require more water for standard consistency. Cement composition: Different types of cement with varying compositions can exhibit different normal consistencies. Curing temperature Time of testing Humidity Testing procedure Chemical admixtures

Im guessing that you mean field test of concrete and not cement. Typically testing for air content, slump, and temperature are performated as outlined by ACI.
The weight of dry cement typically ranges from about 94 to 100 pounds per cubic foot. This can vary slightly depending on the specific type of cement and its composition. For practical purposes, 94 pounds per cubic foot is commonly used in calculations for cement density.
