Moisture content is defined as the ratio of the weight of water to the dry weight of solid particle in a given soil mass. It is expressed in terms of percentage.
The engineering behaviour of soil is largely influenced by the presence of water and its quantity present in the voids of the soil. This test is one of very important soil tests for construction. Therefore, it is necessary to determine the quantity of water present in the soil deposit at a given location.
CanWeighing Balance (with 0.01 accuracy)Thermostatically controlled ovenStep 1: First of all, the soil sample is collected from the site. Step 2: Then, the mass of empty can is recorded (say M1). Step 3: Then, the mass of moist soil and can is recorded (say M2). Step 4: Now, the can containing moist soil is kept in the oven for 24 hours. Then the mass of dry soil with can is recorded (say M3). Step 5: Moisture content ...
The temperature of the oven should be maintained at 110ºC ± 5ºC. But if the soil sample contains a significant amount of gypsum or organic material, the temperature of the oven should be between 60...While putting the can in and taking the can out of the oven special care should be given otherwise, you may burn your hands.The liquid limit of a soil is the minimum water content at which the soil is still in liquid state but has a small setting strength against flowing which can be measure by standard procedure.
Now to analyse and interpret the results for the liquid limit test, a graph is plotted between the number of blows in X-axis and water content in Y-axis on a semi-log graph making use of reading recorded on various tests. The water content corresponding to 25 number of blows is the liquid limit of the soil. In this way we can calculate liquid limit...
The test procedure consists of two parts: 1. Preparing test specimen The test specimen can be prepared by either static compaction or dynamic compaction. The specimen prepared from the dynamic compaction method can be prepared either by light compaction or heavy compaction. In light compaction, the specimen is prepared by filling it in three layers...
The volume of soil, Vs= A * Hs Where A= area of soil solid Hs= thickness of soil solid Precaution 1. The specimen used should be free from voids and over-sized particles. 2. The load should be applied concentrically to the specimen. 3. The inaccuracy that may occur in dial gauge reading should be avoided. Among all types of soil tests for construct...

Nov 28, 2023 · These tests, including the Liquid Limit, Plastic Limit, and Shrinkage Limit tests, assess the soil's consistency and determine its behavior under different moisture conditions. The Liquid Limit test measures the moisture content at which the soil transitions from a liquid to a plastic state.
Nov 30, 2021 · Construction material testing can be divided into two categories: field testing, which occurs at the project site, and laboratory testing, which involves taking samples from the project site back to an off-site location for further analysis.
- Moisture Content Test. Moisture is critical in determining the soil’s weight-bearing capacity. Moisture content, or the amount of water in the soil, is a significant factor in building construction.
- Specific Gravity Test. The specific gravity of soil is the ratio of the unit weight of soil solids to that of water. It is useful to know how permeable the soil is.
- Dry Density Test. The weight of soil particles in a given volume of sample is defined as the dry density of soil. The void ratio and specific gravity of the soil determine the dry density of the soil.
- Atterberg Limits Test. To evaluate the critical water content of fine-grained soil, Atterberg proposed three limits that highlight the properties of fine-grained soil under different conditions.
SOIL CLASSIFICATION AND LABORATORY TESTING 5.0 GENERAL: WEIGHT VOLUME RELATIONSHIP In nature, soils are three-phase systems consisting of solid soil particles, water, and air (or gas). To develop the weight-volume relationships for a soil, the three phases can be separated as shown in Figure 5.1(a).
