(PDF) RELATION BETWEEN UNIAXIAL COMPRESSIVE

This work presents the development of possible empirical relations between UCS values determined by direct and indirect testing methods including Point Load Index and Sonic Velocity for dolerite The presence of vesicles within basalt has a direct impact on the unconfined compressive strength (UCS) of the intact rock Over 130 basalt samples from foundation projects for a large liquid natural gas (LNG) storage facility on north coast of Baja, Mexico, a highrise building in Central, Oregon and a wind turbine project in Northeastern Oregon were selected for laboratory UCS testingEstimating the Unconfined Compressive Strength of Comparative testing of basalt and dolerite indicates that dolerite has better properties for road seals Dolerite has better polished stone values and skid resistance properties The results are considered to be representative of the general quality of dolerite currently quarried However, not REPORT 1991f22Division of Mines and Mineral Resources Report 1991/22

The distinction between dolerite and basalt is of importance in the selection of aggregate It appears that the reliance on a basic petrographic descrip tion (ie dolerite or basalt) as the principle means of distinguishing between sound and unsound aggregate is unwise and that the assumption that dolerites constitute high quality aggregates is not necessarily valid (Orr, 1979)compressive behavior of basalt fiber reinforced composite basalt fiber on compressive strength was carried out for m20 maximum reactivity of quartz powder occurs during basaltic rock 01 Maximum Compressive Strength Of Black Basalt Rock Grey, slightly weathered fine grained, medium jointed hard dolerite rock (Core loss and fracture filling suggest rock mass is highly weathered to spheroidal boulders 50% boulders + 50% matrix not recovered) The secondary colourationof the rock can be an indicator of the degree of weathering/alteration It hasCLASSIFICATION // CHARACTERIZATION OF SOME ROCK

Estimating HoekBrown Rock Mass Strength Parameters

Wood The HoekBrown empirical failure criterion contains three constants: m, s, and ac In Hoek and Brown's words, m and s are "constants which depend on the properties of the rock and upon the extent to which it has been broken before being Sandstone 22–28 Shale 24–28 Slate 27–28 As you can see, rocks of the same type can have a range of densities This is partly due to different rocks of the same type containing different proportions of minerals Granite, for example, can have a quartz content anywhere between 20% and The Density of Common Rocks and Minerals
