Since a large part of the hydropower structures in Sweden was built in the 1950s and 1960s, many of them are slowly but surely exhibiting deterioration. The hydropower companies are facing big challenges and are consequently investing in effective repairing methods since a hydropower structure failure could pose serious consequences and dangers to people, the environment, and the community. Many structures within hydropower are made of concrete and the demands on the new supplementing concrete are high. Concrete with the potential to meet these high demands is the pre-placed aggregate concrete

Abstract Stabilized ferritic stainless steel grades are attractive alternatives to common austenitic grades in sheet metal applications. Compared with older unstabilized ferritic grades, the mechanical and corrosion properties are usually improved. The impurity level, mainly the amount of interstitial carbon and nitrogen, plays an important role in these steels. There are notable issues in the welding of these steels, the most apparent difference to austenitic steels is the susceptibility to brittle failure. This research focused on the influence of minor elements, especially aluminium, calciu

This research addresses the design of reinforced concrete flat slabs for punching shear. Flat slabs are two way spanning slabs without downstand beams that are directly supported by columns. The thickness of flat slabs is typically governed by considerations of either deflection control or punching shear for which there is still no widely accepted theoretical treatment. The research seeks to develop a better understanding of the effects of in-plane restraint and flexural continuity on the punching resistance of flat slabs. The overriding aim is to determine whether flexural continuity is suffi

This project foregrounds the work and perspectives of spoken word poets of Middle Eastern and North African (MENA) descent in connection to the NYC slam poetry scene. I trace the parallel racialization of MENA diaspora communities in the US and the development of slam poetry as a space for raising “othered” voices. Through ethnographic analysis, I consider slam poetry as a site of intersectional struggle, arguing that the engagement of MENA diaspora poets with this scene reveals the ways in which poetry both constitutes resistance to discursive violence through representation and works to mobi

Composite slab flooring systems for steel-framed buildings consist of a profiled steel deck and a cast in-situ slab. The slab traditionally includes a layer of light gauge steel mesh reinforcement. This mesh is placed near the surface, which controls the early-age cracking caused by concrete drying and shrinkage. The steel mesh also performs a vital structural role at high temperatures. Structural fire tests and numerical investigations over the last 15 years have established that the mesh can provide enhanced fire resistance.

Two concrete mixes were designed with 280 kgf/cm2 in the compressive strength and 0.5 in the water to cement ratio with 10%, 20%, and 30% of blast furnace slag or fly ash that were proportioned. Fresh and harden concrete properties of 7, 14, 28, 56, 91, and 120-days moist cured concrete cylinders were assessed. It has to be noted that regular and zinc-coated galvanized rebars were design

These characteristic make magnesium alloys being a potential candidates to replace steel and aluminum alloys in many structural and mechanical applications especially in vehicle application. However, magnesium alloy has high electrochemical activity, and therefore a poor corrosion resistance. Besides, magnesium alloys have poor mechanical properties at high temperature. Accordingly, usage of magnesium alloys are not yet widespread. In this study, using CaCO3

The result of experiment show the corrosion performance of the spray-coated AZ91D is improved with increasing SiO2 content added into cement slurry. When the spray coating containing >12 wt.% SiO2, the corrosion performance of the spray-coated AZ91D is not enhanced and C-S-H (CaO-SiO2-H2O) gel is hindered self-repair. In addition, when 30 wt.

碩士<br>國立雲林科技大學<br>營建工程系碩士班<br>101<br>The environment of Taiwan is hot and wet. When moisture permeates into concrete of structure, calcium hydroxide forms and is carried to the surface of concrete to form efflorescence. Agent of inhibitor for efflorescence was developed for retard calcium hydroxide and moisture. Slag of waste contains heavy metal. Cement products using slag of waste always have problems of diffusing of heavy metal and efflorescence. Agent of inhibitor for efflorescence is applied in this study to solve the problems.

The construction of the port is accompanied by problems such as silt accumulation in the port, the retreat of the surrounding coastline, and disappearance of the beach. Therefore, the dredging operation of the port and sand fill works around the port are environmental sustainability issues. This study uses the dredged sediment from the Mai-Liao harbor to add the BOF slag as a more anti-erosion and shear-resistant backfill material. The BOF slag is the by-product

Three interior and three exterior fiber reinforced slab-column connections were subjected to gravity loads and then tested under lateral load simulating earthquake forces. Test results were compared to previous tests on non-fiber slab-column connections. Addition of steel fiber to the concrete matrix greatly increased the ductility and the energy dissipation capacity of all specimens. Fiber reinforcement also enhanced the shear capacity of interior connections. The failure mode switched from punching shear in interior connections with small amount or no fiber reinforcement to flexure failure i

However, the one-dimensional transient heat conduction problems frequently encountered in the industry have not been tackled to predict the change din temperature over time simply based on a concept similar to the thermal resistance. Although the method of solution for time-dependent temperature variations within a composite slab has been developed for some time, its implementation is quite complex and cumbersome. This i

The aim of this study was to assess the strength, durability properties and corrosion resistance of concrete samples using supplementary cementitious blended materials. In this investigation, three supplementary concrete materials (SCMs) were used together with ordinary Portland Cement (OPC) to form cementitious blends at different proportions. The supplementary materials are silica fume (SF), ground granulated blast furnace slag (GGBS) and fly ash (FA). Sixteen (16) different proportions of the cementitious blends were produced. Tests carried out on concrete samples include slump test, compre

In order to determine the seismic response of existing reinforced concrete non-ductile flat-plate buildings, four reinforced concrete slab-column connection subassemblies designed for gravity load only were built at half-scale of prototype structure, and tested at Ryon laboratory of the Rice University. Each specimen had two exterior and one interior connections. The variables included the presence of spandrel beam, magnitude of gravity load, and reinforcing arrangement. The behavior of entire subassemblies and the individual connections under the cyclic loading was studied in terms of failure

Although epithelial-mesenchymal transition (EMT) can predict resistance to EGFR TKIs, the molecular mechanisms are still unknown. Objectives: To examine the role of EMT regulators in resistance to gefitinib. Methods: The expression level of EMT regulators in gefitinib-sensitive cells (PC9) and gefitinib-resistant cells (PC9/gef) was determined using q
