Unconfined Compressive Strength (UCS) Testing Machine | CBR or UCS Machine - Qinsun

Описание: Introduction:
The Qinsun UCS Machine is a laboratory device designed to measure the unconfined compressive strength of cohesive soils. It is widely used in geotechnical engineering, construction quality control, and research laboratories. The machine is equipped with a high-precision load frame, digital load and displacement sensors, and a user-friendly control interface for accurate and repeatable testing.

Application:
Determination of unconfined compressive strength of cohesive soils
Soil strength assessment for foundations, embankments, and earthworks Research and teaching in soil mechanics laboratories
Quality control of soil improvement and stabilization projects
