To assist the oven drying of large test, samples, it is advisable to use containers having large surface area and break up the material into smaller aggregations. With the cap of the instrument pointed away from the operator, slowly release the gas pressure. The table below compares the two methods and provides an overview of the … Note: 2. gm = gram. of empty Cont. The acceptable range of moisture content in wood flooring is within 2% to 4% of your subfloor’s moisture level. �9�b���� j��.��g���^孔��Y֮�̫iQ�"[�q�+���ȿF[^~Q��'.��c Formwork (Shuttering) for Concrete [Its Types, Design]. 5. 3.4. SO, from the above observations and calculations, the mean moisture content of the soil sample is 34.37%. If it is suspected that gypsum is present in the soil the soil sample should not be subjected to a temperature beyond 80° C. Otherwise, gypsum would lose its water of crystallization affecting thereby the results of moisture content. Ans: The formula for the determination of moisture content is. Principles. In this process, measuring accuracy and the resolution of the balance are extremely important.
