May 10, 2024 · By deploying soil testing for building construction, stakeholders take a critical step in doing due diligence when determining a project’s feasibility. This testing essentially gives them X-ray vision to see what’s happening underneath the ground.
Nov 28, 2023 · By working with Terradyne to conduct these soil tests, your construction professionals can gather valuable information about soil properties, enabling them to make informed decisions and ensure the safety and durability of structures.

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...
Laboratory tests are performed to define soil properties and identify those soils that do not conform to project specifications. For moisture content, strength and stability, the early identification of issues helps avoid future problems and allows for the correction of problems during construction. Concrete & Masonry.
- Moisture Content Test: Various moisture content tests are frequently employed in the construction industry to determine the soil's water amount. These techniques include the alcohol method, radiation method, sand bath method, Pycnometer method, torsion balance method, calcium carbide method, and oven-drying method The oven-drying method, which involves weighing the sample soil, drying it at 110 degrees, and then considering it again to determine the difference, is the most widely used technique for determining moisture content.
- Atterberg Limits Test. This kind of test is used to determine the fine-grained soil's essential water content. The qualities of fine-grained soil can be measured using three limits
- Specific Gravity Test: The density ratio of water to the substance's density determines the specific gravity of any given material. The type of material being tested and the level of precision needed are two examples of the elements that influence the method chosen.
- Dry Density Test. In the dry density test, the weight of the soil particles in a given sample is used to calculate the dry density of the soil. The soil's specific gravity and void ratio determine its dry density, which is then used to categorise the soil into three densities: loose, medium dense, and dense.
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.
