Developing Cost Estimation Models for Road Rehabilitation and Reconstruction: Case Study of Projects in Europe and Central Asia
(ASCE - American Society of Civil Engineers, 2014)
This paper presents the development of prediction models for the unit costs of road works that could be applied to strategic planning of road works at the network level. A specialized data set was used, which was generated ...
Drying simulation of shrinkable clay tiles using variable diffusivity model
(Trans Tech Publications Ltd, Stafa-Zurich, 2014)
This paper represents the upgrade of our previous study in which we have presented a model for simulation of the drying kinetic and estimation of the effective moisture diffusivity of clay tiles using a constant diffusivity ...
Characterisation of collapsing loess by seismic dilatometer
(Elsevier, Amsterdam, 2014)
Structural collapse and sudden volume changes represent a major geotechnical issue, particularly in loess soils. There are different criteria for assessing collapse potential based on laboratory test results, which require ...
Thermal and mineralogical characterization of loess heavy clays for potential use in brick industry
(Elsevier, Amsterdam, 2014)
This paper describes a study of 11 selected samples of loess soil from Serbia, by using differential scanning calorimetry, simultaneously with thermogravimetry and its differential calculation, known as simultaneous thermal ...
Analysis of trace elements in surface sediments, mussels, seagrass and seawater along the southeastern Adriatic coast - a chemometric approach
(Walter De Gruyter Gmbh, Berlin, 2014)
Surface sediments, mussels, seagrass, surface and bottom seawater samples were collected from the costal area of the southeastern Adriatic Sea and analyzed in order to determine the concentration and origin of the following ...
Analysis of Moisture Transfer During the Drying of Clay Tiles with Particular Reference to an Estimation of the Time-Dependent Effective Diffusivity
(Taylor & Francis Inc, Philadelphia, 2014)
The description of the drying process was reduced to the establishment of a series of theoretical and empirical drying models. The complex processes of simultaneous moisture and heat transfer, which are often nonstationary, ...
The effects of chemical composition and firing temperature in heavy clay brick production - Chemometric approach
(Expert Fachmedien GmbH, 2014)
Factors influencing final clay brick properties are numerous, since the raw materials are highly heterogeneous. The chemometric approach is rarely used in analysis in this field, although it could significantly improve ...
Assessment of intensive grinding effects on alumina as refractory compound: Acceleration of gamma to alpha phase transformation mechanism
(Elsevier Sci Ltd, Oxford, 2014)
In this study, the feasibility of alumina phase transition enhancement by mechanical activation was conducted. It was showed that the milling environment plays an important role on the physical, chemical and thermal behavior ...
Comparative kinetic study of mechanical activation process of mica and talc for industrial application
(Elsevier Sci Ltd, Oxford, 2014)
Mica and talc have wide areas of application as a raw material in a number of industrial branches. Mechanically activated mica has specific applications such as: capacitors, insulators, and pearlescent pigments. Talc is ...
ANN model of brick properties using LPNORM calculation of minerals content
(Elsevier Sci Ltd, Oxford, 2014)
Mineralogical composition of heavy clays is one of the most important properties when stadying raw materials in brick industry. Within this study, quantitative determination of minerals using LPNORM calculation was performed, ...
