Nitrogen generator is a nitrogen generator that obtains nitrogen by electrolytically adsorbing oxygen in the air. It is mainly composed of an electrolytic cell, a gas circuit, and a circuit system.After starting up, the oxygen between the cathodes of the electrolytic cell is electrolyzed and mo...

High-purity hydrogen generator obtains hydrogen through electrolysis of water, and is composed of a control power supply, an electrolytic cell, a gas circuit, etc.

Modulus is the ratio of stress to strain in a material under stress.Corresponding to different stress states, it is divided into tensile modulus, shear modulus, and compression modulus, etc. Due to the special physical properties of soil and rock materials, the elastic modulus, deformation modu...

The shear strength indices of soil are its cohesion (c) and angle of internal friction (φ). These two indices are important parameters used to describe the soil's ability to resist shear failure and are widely used in geotechnical engineering. Simply put, they together determine the stabili...

The purpose of Soil Compactor Test Equipment is to measure the relationship between Density and moisture content of soil using standard compaction method.In order to determine the maximum density and optimum moisture content of soil. Applicable to the current national standard and water conserv...

According to the "Code for Fire Protection Design of Buildings", flash point is the lowest temperature at which a mixture of vapor and air generated on the surface of a flammable liquid or solid can flash upon contact with an ignition source under specified test conditions (determined using the...

Standard penetration test (SPT) results can determine soil properties and assess foundation bearing capacity. SPT also has wide applications in pile foundation design and seismic liquefaction assessment. The accuracy of the equipment is crucial for SPT, just as a precision balance is essential ...

The Standard Penetration Test (SPT) is a type of dynamic penetration test that plays a crucial role in in-situ testing of geotechnical engineering.Using a 63.5 kg hammer, a split-tube penetrator of a specific specification is driven into the soil at the bottom of a borehole from a drop height o...

Dynamic Penetrator DCP: This device uses a free-falling hammer to impact the probe into the soil. It is suitable for relatively hard strata such as sandy soil and gravelly soil. It is easy to operate and can quickly assess the bearing capacity of the foundation.DCP is an extensively used conven...

In road engineering, the selection of aggregates directly affects the strength, durability, and skid resistance of the pavement. The following are commonly used aggregate types and their characteristics in road engineering.

This article, titled "Damage constitutive prediction model for rock under freeze-thaw cycles based on mesoscopic damage definition," was published in the journal *Engineering Fracture Mechanics* by Lecturer Meng Xiangzhen and colleagues from Yulin University. The paper defines rock as exhibitin...
