A thorough knowledge of the variations of mechanical properties of rock materials with their
water content is essential for evaluating the structural behaviour and durability of stone …

Due to several great floods in Central Europe the Ministry of the Hungarian Cultural Heritage
engaged the Department of Engineering Geology at the Technical University of Budapest to …

Two types of Hungarian travertine a massive less porous and a laminated porous type were
tested under laboratory conditions. Tests aimed to assess the performance and durability of …

Volcanic tuffs naturally show a strong heterogeneity in their petrography and petrophysical
properties. The arrangement of the components in tuffs can create a very wide spectrum of …

The goal of this paper is to present the influence of the water saturation of the intact rock on
different mechanical parameters, such as internal friction angle, cohesion, Hoek-Brown …

The unconfined compressive strength (UCS) of a rock is a basic parameter for many
characterization systems, strength criteria and calculation methods. It is well-known fact that …

Steep, hardly accessible cliffs of rhyolite tuff in NE Hungary are prone to rockfalls,
endangering visitors of a castle. Remote sensing techniques were employed to obtain data …

Abstract Neapolitan Yellow Tuff (NYT) has been used in construction in Naples (Italy) since
the Greeks founded the city—then called Neapolis—in the sixth century BCE. We investigate …

Many cultural heritage sites in Mexico have been built with volcanic tuff rocks from the
earliest Central American civilizations to the time of the Spanish conquest and up to the …

Tuff rock is highly heterogeneous due to volcanic activity, hydrothermal alteration, and
weathering. It is difficult to explain the deterioration mechanisms of the weathered rocks …
