Index properties and strength variation controlled by microstructure for sedimentary rocks

Prediction of the uniaxial compressive strength and Brazilian tensile strength of weak conglomerate

“…There are various studies in the literature proposing relationship between I s(50) and UCS on different rock types but not on conglomerates individually: Oztruk and Altinpinar [6], Ferentinou and Fakir [7], Basu et al [8], Akram and Bakar [9], Quane and Russel [10], Kahraman [11], Fener et al [12], Basu and Aydin [13], Agustawijaia [14], Cobanoglu and Celik [15], Sabatakakis et al [16], Kahraman and Gunaydin [17]. Table 1 lists some of the equations correlating the UCS to I s(50) .…”

Geotechnical and mineralogical properties of weak rocks from Central Greece

“…The Uniaxial Compressive strength was indirectly measured using the Point load test which was developed as an index test, since the samples appeared to be very broken, at least for the UCS testing method. The Point load test is widely used to determine the uniaxial compressive strength indirectly, because of its ease of testing, simplicity of sample preparation and in some case field application ( [34][35][36][37][38][39][40][41][42][43][44][45]). A correlation factor (k) between UCS and PLT strength of 12.5 has been proposed according to Brook (1980) [46], although, the value of K is disputed by many researchers.…”

Suitability Assessment of Gretageous Limestones From Thermo (Aitolokarnania, Western Greece) for Their Use as Base and Sub-Base Aggregates in Road-Construction

“…The somewhat higher Los Angeles values of samples ΑΤ22Α and ΑΤ22Β are interpretaed as the result of their sparitic texture (e.g. Zarif & Tuğrul, 2003;Sabatakakis et al, 2008).…”
