The microstructure and mineralogy of volcanic rocks is varied and complex, and their
mechanical behaviour is similarly varied and complex. This review summarises recent …

The uniaxial compressive strength (UCS) is one of the most important parameters for
judging the mechanical behaviour of rock mass in rock engineering design and excavation …

This paper presents a comparative evaluation of efficacies of different index tests and
analysis techniques (ie regression analyses and fuzzy inference system) in predicting …

The elastic modulus of intact rock is used for many rock engineering projects, such as
tunnels, slopes, and foundations, but due to the requirements of high-quality core samples …

Although the uniaxial compressive strength and modulus of elasticity of intact rocks are
highly important parameters for rock engineering and engineering geology projects, the …

Weathering processes cause important changes in rock porosity. Besides porosity,
distribution of pore sizes is significant for the identification of changes due to rock …

The presence of non-connected vesicles in extensive basalt flows in western Saudi Arabia
greatly affects their engineering properties such as compressive strength, modulus of …

The uniaxial compressive strength (UCS) of rock is an important parameter required for
design and analysis of rock structures, and rock mass classification. Uniaxial compression …

Empirical relationships for estimating Uniaxial Compressive Strength (UCS) of rock from
other rock properties are numerous in literature. This is because the laboratory procedure for …

The mechanical behavior of engineering materials, whether of natural or artificial origin,
varies with their internal structure. As the uniaxial strength σu is commonly used to …
