This investigation was performed to establish the effects of the source and amount of fly ash on abrasion resistance of concrete. A reference concrete was proportioned to have a 28day age strength of 41 MPa. Three sources of Class C fly ash were used in this research. From each source, three levels of fly ash to total cementitious materials content (40, 50, and 60%) were used in producing the c...

This paper describes the results of room temperature joining of TiO2 / SiO2 IRF by sputter deposition with a special emphasis of improvement of adherence at the interface. This multilayer system is designed to shield the infrared energy of solar spectrum by interference reflection. The abrasion resistance of the multilayer stacks was also estimated by the Haze value after the Taber abrasion tes...

OBJECTIVES To attain alliance between the oral hygiene practices with prevalence of tooth abrasion among urban and rural adult population of Central India. To plan dental care services in inaccessible areas and to suggest appropriate remedial measures to prevent this avertable and self-inflicted injury of teeth in this cross-sectional study. MATERIALS AND METHODS A sum of 1045 adult residents...

In this study, the synergistic effects of abrasion and corrosion on UNS S30403, S31603 and S32760 stainless steels have been investigated using micro-abrasion test rig. The stainless steel samples have been studied under both pure abrasion (PA) and abrasion–corrosion (AC) conditions imulated by using silicon carbide based slurries in either distilled water or 3.5% sodium chloride solutions. Tes...

an experimental program was carried out to investigate the behavior of steel, fiber reinforced concrete (sfrc) under abrasion and cycles of freeze and them. compression and flexural tests were also performed in order to reach a comprehensive conclusion of the response. in total, over 200 specimens were tested the test variables included two concrete strength., (i. e., 28 mpa as normal strength ...

The installation procedures (which induce mechanical damage) and abrasion can cause unwanted changes on the properties of the geotextiles. In this work, a nonwoven polypropylene geotextile was subjected to three degradation tests: (1) mechanical damage, (2) abrasion and (3) mechanical damage followed by abrasion (successive exposure). The damage caused by the degradation tests was evaluated by ...
