FAQs of Unconfined Compression Test Apparatus:

Q: How is the Unconfined Compression Test performed using this apparatus?

A: The test is conducted by placing a cylindrical soil specimen between the loading pad and compression plate. Manual loading is applied via the screw mechanism at a constant rate of 1.25 mm/min. Deformation is recorded with the dial gauge, and the sample is compressed until failure, allowing calculation of soil strength.

Q: What sample sizes are compatible with this equipment?

A: This apparatus supports cylindrical specimens with diameters of 38 mm or 50 mm and heights ranging from 76 to 100 mm, complying with IS: 2720 (Part X) and ASTM D2166 standards for soil testing.

Q: When should this apparatus be used in soil analysis?

A: It is used during laboratory soil investigations to determine unconfined compressive strength, which aids in evaluating soil stability for construction, foundation, and geotechnical engineering projects.

Q: Where is the ideal setting to operate the Unconfined Compression Test Apparatus?

A: The device is designed for indoor laboratory use under ambient temperature conditions. Its portable and compact design allows easy placement on standard laboratory benches.

Q: What is the process of measuring load and deformation in this apparatus?

A: As the sample is loaded, the applied force is indicated on the dial gauge, which has fine 0.01 kN graduation. Simultaneously, the dial gauge tracks axial deformation up to 10 mm with 0.01 mm accuracy, allowing precise measurement of specimen response.

Q: Who are the main users and beneficiaries of this product?

A: Laboratory technicians, researchers, quality control engineers, and educators engaged in geotechnical investigations or teaching benefit from this apparatus due to its ease of use, accuracy, and compliance with international standards.

Q: What are the main advantages of using a manual mechanical loading system in soil testing?

A: Manual operation enhances user control over loading speed and pressure application, ensuring precise test conditions. The portability and straightforward setup offer flexibility and reliability for routine and field laboratory applications.
