During diagenesis process, the upper Triassic sandstones Mulussa F reservoir have experienced multiple diagenetic transformations which have an important influence on the petrophysical properties of the reservoir, among them, the influences of the diagenetic / authigenic clay minerals precipitation. Conventional core analysis CCA data combined with petrographical observations have been used to characterize the upper Triassic sandstones reservoir parameters and to define the influence of the diagenetic clay mineral...

The article deals with the prediction of deformation progress of the basement for a high-rise building founded in a deep foundation pit of 12.0 m below the ground level. Foundation consists of a stiff reinforcement concrete raft with basement in a Neogene layer of several ten metres. The deformation progress of the footing bottom is predicted by numerical approach of a finite-element method and the results are subsequently confronted with geotechnical monitoring. For this purpose, the input parameters were calibra...

This paper presents the comparison of selected elements of a single-family building in light clay and traditional technology. The advantages and disadvantages of the properties of several materials used in both technologies are described. Moreover, the history of building using clay and its modern construction application, as well as an overall view of the qualities and varieties of the use of clay as a building material in combination with straw and other elements were showed. The selected object was one of the c...

Lately, in our country, the necessity of expanding the transport infrastructure works has led to the necessity of designing and executing engineering constructions in areas with lands considered difficult in terms of physical and mechanical characteristics. According to the Romanian and European norms, sensitive clay of low consistency is included in the category of difficult land. This paper presents the main research stages of the physico-mechanical properties of sensitive clays found on a section of a highway i...
