Physical Characteristics Of Weathered Granite

Learn more about the properties and uses of granite in this article.

Physical characteristics of weathered granite. Granite coarse or medium grained intrusive igneous rock that is rich in quartz and feldspar. The process of weathering the influence factors on particle breakage and the mechanical properties of compacted weathered granite have been discussed. There are various physical properties of granite like hardness grain size fracture streak porosity luster strength etc which defines it. Compared to the deformation and failure characteristics of unweathered granite the uniaxial compression strength and the elastic modulus of weathered granite are significantly decreased.

However the weathered granite soil with a clay content of approximately 4 had the largest mean value in the cbr tests which was 95. A gravestone made of granite will therefore resist fracturing cracking and chipping longer than a sandstone marker found in the same location. The physical and chemical weathering of a granite will produce. Physical properties of rocks are used to identify the type of rocks and to discover more about them.

The critical confining pressure 100 200 kpa is an indicator to determine the hardening characteristics of compacted weathered granitic soils under different pressures. Granite is hard enough to resist abrasion strong enough to bear significant weight inert enough to resist weathering and it accepts a brilliant polish. Fracture characteristics were investigated in 13 exposures in five study areas in weathered granite in eastern asia. Reduced iron oxides oxidized iron oxides quartz feldspar.

The results show that particle gradation mineral content blows per layer and stress level have a significant effect on the particle breakage characteristics of weathered granite soils. Additionally the acoustic emissions are consistently observed in the stage of original crack closure and loading induced crack initiation followed by crack. Ions dissolved in rainwater and soil water mineral fragments and granite fragments clays and iron oxides all of these. Granite is extremely hard and less affected by the freeze thaw cycle the forces of abrasion and the surface exfoliation processes that are all a part of physical weathering.

Many geotechnical characteristics including weathering are controlled by the density and arrangement of fractures within the rock but the relationships between fracture patterns and weathering grades are typically not addressed. The deep red color of solis found in georgia and other warm humid regions in caused by. Granite is coarse grained has a uniformly dispersed crystalline structure has a specific gravity of 2 6 2 7 is composed of varying amounts of various feldspars quartz micas and other.
