Predicting the Uniaxial Compressive Strength of a Limestone Exposed to High Temperatures by Point Load and Leeb Rebound Hardness Testing

Rock Mechanics and Rock Engineering, 2021
The effect of exposure to high temperature on rock strength is a topic of interest in many engineering fields. In general, rock strength is known to decrease as temperature increases.

Experimental investigation on the point load strength of red-bed siltstone with different shapes

Acta geodynamica et geomaterialia, 2020
The point load test is an indirect method to estimate the uniaxial compressive strength (UCS) of rock. In order to investigate the influence of the shape effect on the point load test strength of the siltstone in the Red Stratum, a series of point load ...

Flexural behaviour of plain concrete prism strengthened by textile fine grained mortar [PDF]

, 2018
This paper presents a flexural strength study of concrete incorporated with textile fine grained mortar (TFGM) as a strengthening laminate. TFGM is a combination of fine grained mortar (FGM) with alkali resistant glass fabric (AR glass).

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 ...
