PREDICTION OF UNCONFINED COMPRESSIVE STRENGTH OF ROCKS BY POINT LOAD STRENGTH INDEX [PDF]

Journal of Al-Azhar University Engineering Sector, 2019
The point load testing is widely used to determine rock strength indeces in geotechnicalpractices as a result to simplicity. The present study presents correlation equations betweenthe unconfined compressive strength (qu) and point load strength index Is(50) adopted fordifferent types of rocks.

Study on the Numerical Relationship between Dynamic Compressive Strength and Crushing Energy Consumption in Dynamic Point Load Test under Different Corrosion Conditions

Shock and Vibration, 2023
Compared with most dynamic tests, point load test is widely used in engineering practice because of its wide requirements for test conditions. In offshore mining engineering, the surrounding rock is affected by dynamic load impact and corrosion of ...

Vibrated concrete vs. self-compacting concrete: comparison of fracture mechanics properties [PDF]

, 2014
This study focuses on the fracture mechanics aspect of self-compacting concrete, compared to vibrated concrete. The most commonly used experiments to investigate the toughness and cracking behaviour of concrete are the three-point bending test (3PBT) on ...

Shear critical R/C columns under increasing axial load [PDF]

, 2020
Structural elements in old reinforced concrete (R/C) frame buildings are often prone to shear or flexure-shear failure, which can eventually lead to loss of axial load capacity of vertical elements and initiate vertical progressive collapse of a building.

Correlation between Uniaxial Compressive Strength and Point Load Strength of Penang Island Granites

IOP Conference Series: Earth and Environmental Science, 2022
Abstract Uniaxial compressive strength (UCS) is one of the most widely used strength parameters in geotechnical design. The value is obtained through direct testing method, carried out through careful procedures of testing in a laboratory setting. As such, it is relatively more expensive, more tedious and requires longer time to complete.
