WebLab Report for Water Content Determination Purpose: This lab is done to calculate the water content of the soil. The water content of the soil is defined as the percentage of water in a given soil mass with respect to its dry soil mass. The moisture content is always a good idea to know about the state of the soil. Standard Reference: ASTM D … WebApr 14, 2024 · The dry density and initial gravimetric water content of compacted soils were listed in Table 1. Nonwoven geotextile was placed between soil layers to minimize particle migration. After compaction, the soil was let stand for 48 h for the dissipation of excess pore water pressure.
WebSome disciplines, such as soil science, need to determine water content on the basis of volume. Such determinations are beyond the scope of this test method. The water content of a material is the ratio of the mass of water contained in the pore spaces of soil or rock material, to the solid mass of particles, expressed as a percentage. Keywords ... WebFeb 13, 2024 · The usual procedure to find the natural water content is to take a mass of about 20 g to 30 g of soil sample in a container and determine its mass M very accurately. The soil sample is then kept in an oven (105°C–110°C) for about 24 hours so that it becomes perfectly dry. Its dry mass Md is then determined and the water content is ...
