ACI Aggregate Base Testing Technician Practice Test 2025 – Complete Exam Prep

The mass of the sample that should be taken for the liquid limit test is indeed 100 grams. This specific amount is used to ensure that the sample is sufficient to yield reliable and reproducible results during the testing process. The liquid limit test is designed to determine the moisture content at which clayey soils transition from a plastic state to a liquid state. Using a consistent sample mass, such as 100 grams, allows for standardized testing among different technicians and laboratories, which is essential for comparing results and maintaining quality control in soil testing.

Samples that are too small may not provide accurate measurements due to the variability in materials, while larger samples can lead to unnecessary material waste and complicate the test procedures. Therefore, 100 grams is the optimal amount specified in testing standards for the liquid limit test, balancing practicality with the accuracy needed for the assessment of soil consistency.
