Abstract: Determination of the deformability of jointed rock masses is an important and challenging task in rock mechanics and rock engineering. In this paper, simple expressions are derived for estimating the equivalent isotropic ...

Abstract: The use of the cone penetration test (CPT) resistance data as an index for liquefaction assessments is receiving increased attention because of the advantages of this in-situ test method. This paper investigates the ...

Abstract: This paper presents a method for predicting the nonlinear response of torsionally loaded piles in a two-layer soil profile, such as a clay or sand layer underlain by rock. The shear modulus of the upper soil is assumed to ...

Abstract: This paper presents an experimental study on geopolymer synthesized with class F fly ash (FA) and low-calcium slag (SG). Geopolymer specimens were produced using FA and SG at different relative amounts (FA/SG=0/100, 25/75, ...

Abstract: A great number of rock strength criteria have been proposed over the past decades. Of these different strength criteria, the Hoek-Brown strength criterion has been used most widely, because: (1) it has been developed ...

Abstract: This paper investigates complete recycling of waste concrete to produce new geopolymer concrete (GPC). Specifically, GPC was produced using waste concrete fines (WCF) and class-F fly ash (FA) together with mixed sodium ...

Abstract: This paper investigates the incorporation of ordinary portland cement (OPC) to adjust/improve the workability, setting time, and compressive strength of Class F fly ash (FA)–based geopolymer binder. The geopolymer binder ...
