Alteration of granite stone used in building construction

open access: yesMateriales de Construccion, 2007
The article contains a synthesis of the different factors involved in the alteration of granite ashlars or cladding used in building construction. Emphasis is placed on the – primarily fissure-like – anisotropies often present in granite, which are ...

Experimental Investigation of Moisture Movement During Freeze–Thaw Cycles and Its Effect on Physical Rock Weathering in Low‐Porosity Alpine Limestone

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT The progressive weakening of alpine rockwalls through subcritical cracking, driven by repeated low‐magnitude stress processes, plays a key role in alpine rock weathering. Laboratory studies using acoustic emission (AE) monitoring have shown that thermal stresses from freeze–thaw cycling induce crack propagation, with recent work highlighting ...

Spatial Variability of Permafrost and Active Layer Thickness in a Forested Hillslope of the Taiga Shield

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Under continued climate warming, understanding present‐day permafrost distribution and the controls on ground thaw are critical for predicting permafrost thaw trajectories and associated implications. This study presents a high‐resolution investigation of permafrost extent and active layer thickness (ALT) across a coniferous forested hillslope

Critical Review of Brazil Disk Techniques for Tensile Strength Characterization With an Emphasis on High Explosive Materials

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Mechanical properties are a critical performance metric for many high explosive (HE) materials and tensile strength properties are particularly important. Direct tensile measurements using dogbone shaped samples are the gold standard but they have the disadvantage that they are fairly large and require samples machined from billets.

The regulation of mechanical properties and freeze-thaw properties of concrete hollow block with granite waste

open access: yesJournal of Asian Architecture and Building Engineering
Owing to the generation of waste during mining and processing, granite stone causes great damage to the environment. In this study, the broken granite waste and the stone powder were used as concrete coarse aggregate and “admixture” to make granite waste

Scale and Rock Type Dependency of Mórágy Granite Formation in the Aspect of Fracture Density

open access: yesGeotechnics
The geometry of rock mass fractures is typically characterized through geological and geotechnical investigations. Detailed descriptions of granitic host rock can yield valuable data for constructing fracture network models.
