What to expect from heavy clay?
(Elsevier Sci Ltd, Oxford, 2013)
The need of testing the quality of brickclay arises in all brick factories, with the opening of new deposits. The analyses are both time and economically consuming, so the aim of this study was to shorten the procedure ...
Tie-rods of the bucket wheel excavator slewing superstructure: A study of the eye plate stress state
(Elsevier Sci Ltd, Oxford, 2020)
Tie-rods of the bucket wheel and counterweight booms are vital parts of the bucket wheel excavator slewing superstructure. This paper is dedicated to the problem of identifying the stress state of the critical cross-section ...
Factor space differentiation of brick clays according to mineral content: Prediction of final brick product quality
(Elsevier Science Bv, Amsterdam, 2015)
Chemical composition and XRD qualitative analysis were used to calculate mineral contents of 139 brick clay raw materials using LPNORM. The second order polynomial models (SOP) for all the samples, which express the relation ...
Novel Utilization of Fly Ash for High-Temperature Mortars: Phase Composition, Microstructure and Performances Correlation
(Wiley, Hoboken, 2015)
In this study, the feasibility of using fly ash to manufacture high-temperature mortars was investigated. The investigation was set to define preliminary characteristics of new types of mortars based on ordinary and/or ...
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 ...
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, ...
