An investigation focused on the transformation and distribution behaviors of trace elements and natural radionuclides around a coal gangue brick plant was conducted. Simultaneous sampling of coal gangue, brick, fly ash and flue gas were implemented. Soil, soybean and earthworm samples around the brick plant were also collected for comprehensive ecological assessment. During the firing process, ...

Vermiculite is a hydrous clay mineral that occasionally occurs in raw materials for brickmaking. The presence of vermiculite affects the drying and firing processes brick production; thus, functions this should be clarified. In study, from 0 wt% to 30 have been added mixtures button firing. Through effective integration in-situ XRD, thermogravimetric dilatometric analyses, real-time thermal beh...

Low-frequency noise spectroscopy is used to examine the interactions between resistive and conductive films that take place during thick-film resistor (TFR) fabrication. Two noise parameters are introduced to quantitatively describe the strength of these interactions. They refer to intensity and repeatability of the noise generated in the resistor interfaces. Extensive experimental studies perf...

For the development of force sensors, manufactured in LTCC (low temperature co-fired ceramics) technology for musical wind instruments, the mechanical properties of laminated LTCC tapes were characterized. Since one layer of LTCC tape is not always fulfilling the requirements of the force sensor’s loading capacity, the influence of lamination parameters for different number of layers were inves...

Background Manual brick-manufacturing units in India engage a large number of female workers on a daily-wage basis for a period of 8 months per year. There are two groups of female workers in the brickfields: the brick molders and the brick carriers. These brickfields are mostly unorganized, and the workers are exposed to extreme conditions such as very high seasonal heat. The present trend of ...

This paper examines the effect of non-uniformmicrostructures on themacroscopic fracture properties of idealized brick and mortar composites, which consist of rigid bricks bonded with elastic–plastic mortar that ruptures at finite strain. A simulation tool that harnesses the parallel processing power of graphics processing units (GPUs) was used to simulate fracture in virtual specimens, whose mi...

This paper presents a novel interface element for the geometric and material nonlinear analysis of unreinforced brick-masonry structures. In the proposed modelling approach, the blocks are modelled using 3D continuum solid elements, while the mortar and brick-mortar interfaces are modelled by means of the 2D nonlinear interface element. This enables the representation of any 3D arrangement for ...

BACKGROUND Bricks have been manufactured in Nepal for hundreds of years and are seen as a component of Nepalese sculpture and architecture. Large quantities of hazardous materials including high concentrations of particulate matter are emitted on a daily basis from brick kilns. Exposure to these hazardous materials can lead to adverse consequences on the environment and human health. This study...

In recent years, the management of construction and demolition residues (CDRs) has become a major challenge for industry due to increasing volume waste produced its associated environmental impact. The aim this article is assess effect fine-grained fractions (<0.125 mm–0.6–0.125 mm) residues, obtained by industrial sorting in CDR processing plant Rovigo (Italy), on technological behavior tec...

This thesis presents a virtual disk cluster called END, the Expandable Network Disk. END aggregates storage on a cluster of servers into a single virtual disk. END'S main goals are to offer good performance during normal operation, and efficiently handle changes in the cluster membership. END achieves these goals using a two-layer design, in which storage "bricks," servers that consist of CPU, ...
