© 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/m3, and two different aggregate gradations with maximum aggregate sizes of 12 mm and 19 mm to investigate the effect of mixture design on RCC mechanical performance and fracture properties. All RCC mixtures were compacted in a plate mold with dimensions of 15x85x200 cm3 by applying first a vibratory plate compactor, then a double drum vibratory hand roller to simulate the actual field compaction procedures. Cores and prismatic beam specimens were taken from the plates to determine the strength and fracture properties of RCC mixtures. Single-point bending test was applied on the notched beams to determine the fracture parameters by using RILEM procedure based on the non-linear two parameter fracture model. According to the statistical analysis results, it was found that the strength and the fracture properties of RCC mixtures were affected not only by the mixture proportions but also by the compaction amount. Moreover, it was shown that the critical stress intensity factor (KIc) was enhanced with the increase of maximum aggregate size, compaction ratio, then binder dosage. On the other hand, critical crack tip opening displacement, CTODc seems to be affected only by the fine to total aggregate ratio or the maximum aggregate size.

Strength of carbon fiber reinforced polymers bonded to concrete and masonry Serdar Camli, Umit; Binici, Barış (Elsevier BV, 2007-07-01) 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 t...
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...
Laboratory evaluation of dry process crumb rubber modified mixtures containing Warm Mix Asphalt Additives Öztürk, Hande Işık (Elsevier BV, 2019-12-30) Crumb rubber (CR) usage in asphalt pavement sector is an environmentally friendly and economical solution. However, the production temperatures are significantly higher than the traditional mixtures. Thus, the focus of this study is to use Warm Mix Asphalt (WMA) additives in dry process CR modified mixtures to overcome high temperature needs without compromising the performance. Effect of WMA additive on conditioning time, mixing and compaction temperatures, and also rutting and cracking potentials were inv...
Investigation of Moisture Dissipation in Foam-Based Warm Mix Asphalt Using Synchrotron-Based X-Ray Microtomography Kutay, M. Emin; Öztürk, Hande Işık (American Society of Civil Engineers (ASCE), 2012-06-04) Foam-based Warm Mix Asphalt (WMA) technologies decrease the viscosity of the asphalt so that it is workable during construction. However, after construction, viscosity increases rapidly as the foam disappears and temperature drops. During the process of dissipation of foam, depending on the environmental conditions, the moisture may not escape and may be trapped inside the mixture. This trapped moisture can cause detrimental failures by breaking the adhesive bonds between the aggregates and the asphalt bind...
