Product Description

Product Description

The Unconfined Compression Test Apparatus is a precision instrument designed for both laboratory and field use. It is engineered to meet rigorous standards, ensuring accurate results in geotechnical soil analysis. Manufactured using high-quality materials, this apparatus provides reliable performance for professional engineering requirements.

The system consists of a spring-operated load frame specifically arranged for loading 38 mm x 76 mm samples. It features a versatile set of four load springs with varying stiffness (0.2 kg/mm, 0.4 kg/mm, 0.8 kg/mm, and 1.6 kg/mm) to accommodate different soil strengths. For field portability, the entire set is housed in a durable metal carrying case.

Key Applications & Components
1
Strength Determination: Used for the determination of unconfined compressive strength (qu) of cohesive soils, such as clay and silty clay.
2
Sensitivity Evaluation: Evaluates the sensitivity of soil (St), measuring the ratio of strength between undisturbed and remolded soil samples.
3
Engineering Stability: Ideal for soil stability analysis and the estimation of foundation bearing capacity in construction projects.
Included Accessories:
  • Calibrated mask and set of 50 charts.
  • Spring set: 2 N/mm, 4 N/mm, 8 N/mm, and 16 N/mm.
  • Coning tools for 38 mm samples (male and female).
  • Wooden tripod stand for field instrument stabilization.

Frequently Asked Questions
What is the primary function of the Unconfined Compression Test Apparatus?
It is primarily used to determine the unconfined compressive strength (qu) of cohesive soils and to calculate soil sensitivity by comparing undisturbed and remolded samples.
What sample sizes are compatible with this equipment?
The standard loading frame is designed for 38 mm x 76 mm samples, while the technical specifications support soil samples up to 40 mm in diameter and 100 mm in height.
Does this apparatus support electric operation?
Yes, the device features dual operation modes: a manual mode (0.058mm per round) and an electric mode with a climbing speed of 2mm/min.
Is this equipment suitable for on-site field testing?
Absolutely. It comes with a wooden tripod stand and a metal carrying case, making it highly portable and stable for field engineering applications.
What is included in the spring set?
The apparatus includes a set of four springs with stiffness ratings of 2 N/mm, 4 N/mm, 8 N/mm, and 16 N/mm (corresponding to 0.2 kg to 1.6 kg/mm) to handle various soil types.
How precise is the displacement measurement?
The dial indicator provides a range of 30mm with a high-precision division value of 0.01mm for accurate axial displacement tracking.
