Fiber reinforced polymers (FRPs) have gained popularity in upgrades of reinforced concrete structural elements within the last decade because of their ease of application and high strength-to-weight ratio. In the design of an effective retrofitting solution using FRP systems, the anchorage capacity has an important role. This study presents the results of 57 double shear push-out tests conducted to determine the strength of carbon fiber reinforced polymers (CFRPs) bonded to concrete prisms and hollow clay tiles that are finished with and without plaster. In the experimental program, different types of anchorage methods were tested in a double shear push-out test setup. It was observed that presence of a plaster finish adversely affects the strength of CFRPs bonded to concrete or masonry. Furthermore, it was found that strength of CFRPs bonded to hollow clay tiles are significantly lower than CFRPs bonded to concrete. The proposed embedded anchors acting as shear connector were found to significantly improve the ultimate strength of surface bonded CFRPs both in the presence and absence of plaster finishing. A simple and effective strength model, calibrated using the experimental results, is verified for FRP anchors based on the existing analytical models and experimental observations from this and other studies reported in the literature.

Anchorage strength of fiber reinforced polymers Çamlı, Ümit Serdar; Binici, Barış; Department of Civil Engineering (2005) Fiber reinforced polymers (FRPs) have gained popularity in upgrade projects for reinforced concrete structural elements within the last decade because of its ease of application and high strength-to-weight ratio. In the design of an effective retrofitting solution by means of an FRP system, the anchorage capacity has an important role.

Strength and fracture properties of roller compacted concrete (RCC) prepared by an in-situ compaction procedure ŞENGÜN, EMİN; Aleessa Alam, Burhan; Shabani, R.; Yaman, İsmail Özgür (Elsevier BV, 2020-01-01) © 2020 Elsevier LtdThe use of roller compacted concrete (RCC) technology in pavement applications has been steadily increasing owing to its economical as well as practical advantages. Past literature studies on RCC mixtures, focused mainly on the effects of RCC mixtures on their strength and durability properties, and there is a lack in the fracture properties. In this experimental study, a total of seven different RCC mixtures were designed with four different binder ratios ranging from 200 kg/m3 to 600 kg...
Properties of blended cements with thermally activated kaolin Arikan, Metin; Sobolev, Konstantin; Ertuen, Tomris; Yeginobali, Asim; Turker, Pelin (Elsevier BV, 2009-01-01) Kaolin, one of the materials of major importance for the ceramic and paper industry, is also used in the construction industry as a raw material for the production of white cement clinker and, in the form of metakaolin, as an artificial pozzolanic additive for concrete. Metakaolin is a vital component of high-performance and architectural concrete; however, its application in regular concrete is very limited due to relatively high production costs. This report evaluates the performance of a low-cost metakao...
Seismic strengthening of reinforced concrete frames by precast concrete panels BARAN, MEHMET; Susoy, M.; Okuyucu, D.; Tankut, T. (Thomas Telford Ltd., 2011-05-01) An innovative occupant-friendly retrofitting technique has been developed for reinforced concrete (RC)-framed structures which constitute the major portion of the existing building stock. The idea is to convert the existing hollow brick infill wall into a load-carrying system acting as a cast-in-place concrete shear wall by reinforcing it with relatively thin high-strength precast concrete panels epoxy bonded to the plastered infill wall and epoxy connected to the frame members. In this study, results of 11...
Comprehensive Evaluation of AIMS Texture, Angularity, and Dimension Measurements Mahmoud, Enad; Gates, Leslie; Masad, Eyad; Erdoğan, Sinan Turhan; Garboczi, Edward (American Society of Civil Engineers (ASCE), 2010-04-01) Aggregates are the most widely used construction materials in the world in structures built from both asphaltic and portland cement concrete composites. The performance of these composites is affected by aggregate shape characteristics (e.g., angularity, texture, and dimensions). The aggregate imaging system (AIMS) is a computer automated system that was developed to measure aggregate shape characteristics using digital camera images of aggregates. This paper addresses four issues concerning AIMS measuremen...
