Application of neural networks in determination of compressive strength of concrete
(Revista Romana de Materiale/ Romanian Journal of Materials, 2012)
This paper presents the optimization of concrete mixtures composition related to a physical property and the process of production of trial mix design by using the multi-layered feed-forward neural networks. This optimization ...
Determination of the effective diffusion coefficient
(Revista Romana de Materiale/ Romanian Journal of Materials, 2011)
The equation for drying kinetics is obtained, base on the analytical solution of the differential equation with a boundary condition in the form of the flux. This equation was initially developed by G. Efremov. In this ...
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 ...
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 ...
The effect of mechano-chemical activation and surface treatment of limestone filler on the properties of construction composites
(Elsevier Sci Ltd, Oxford, 2017)
The effect of the combined actions of milling and hydrophobization procedures applied in construction composites synthesis was investigated. The mortars were prepared with cement (CEM I 42.5) and calcite aggregate complying ...
Application of Organic and Inorganic Wastes in Clay Brick Production: A Chemometric Approach
(Wiley Blackwell, 2016)
The goal of this study was the research on the usage capability of various industrial wastes in clay bricks. Changes in product's behavior were studied in terms of relative differences in ceramic-technological parameters ...
Mathematical approach to application of industrial wastes in clay brick production - Part I: Testing and analysis
(Elsevier Sci Ltd, Oxford, 2015)
The objective of this study was to investigate utilization potential of organic and inorganic industrial wastes in clay bricks. Mineral composition of starting heavy clay sample is tested using an X-ray diffractometer. ...
Mathematical approach to application of industrial wastes in clay brick production-Part II: Optimization
(Elsevier Sci Ltd, Oxford, 2015)
The effects of organic and inorganic waste sludges, coal dust, fly and landfill ashes, soybean crust, sawdust, sunflower flakes and their ash addition to representative heavy clay were investigated. Changes introduced to ...
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, ...
