One of the significant imperfections of prestressed cylinder concrete pipe (PCCP) which leads to fatal failure is corrosion in spiral rebars. The use of PCCP is very widespread, but most often, their instantaneous failures are experienced. In this paper, acoustic emission (AE) technique was employed to detect corrosion in PCCP. To achieve this object three experimental specimens were made in the laboratory of Middle East Technical University. Each specimen was built for the specific aim in which the third one was the almost full-scale sample of PCCP. The pipe was loaded internally by water pressure and accelerated corrosion test was conducted on the specimens. For detecting the corrosion, especially for identifying the passive damages, water pressure was fluctuated during the experiment in both dry and wet conditions along with using the Kaiser Effect phenomenon in both conditions. It was observed that significant changes in some captured AE parameters occur as the pipe pressure exceeds the previous level by which the condition assessment is made feasible. Results indicated that the proposed technique is an efficient procedure for evaluating both active and passive damage types in PCCP.

Analysis of the effects of vertical pre-release cracks on prestressed concrete bridge girders Baran, Eray; French, Catherine; Wyffels, Tina (Precast/Prestressed Concrete Institute, 2004-11-01) Vertical cracks, termed "pre-release cracks," beginning at the top flange and propagating downward into the section depth have been observed to develop during the production of long-span prestressed concrete bridge girders. The cracking which is attributed to the restrained shrinkage the concrete and thermal effects during the curing period prior to release of the prestressing strands, tends to be more critical for long-span girders with deep sections and large amounts of prestressing strands. Studies were ...
Influence of elevated temperature on axially loaded expansive cement grout borehole plug sealing performance Akgün, Haluk (Thomas Telford Ltd., 2000-10-01) The strength of expansive cement grout borehole plugs cast in rock cylinders is investigated theoretically and experimentally as a function of curing and testing temperature of the plugged rock cylinder and of borehole size. The distributions of thermally induced stresses and displacements, shear stresses along the plug-rock interface due to an axial stress applied to the plug, and resultant interfacial shear stresses due to a combination of uniform elevated temperature and axial load are studied and analys...
Determination of the elastic properties of amorphous materials: Case study of alkali-silica reaction gel Moon, Juhyuk; Speziale, Sergio; Akgül, Çağla; KALKAN, BORA; Clark, Simon M; Monteiro, Paulo JM (Elsevier BV, 2013-12-01) The gel formed during alkali-silica reaction (ASR) can lead to cracking and deterioration of a concrete structure. The elastic properties of the ASR gel using X-ray absorption and Brillouin spectroscopy measurements are reported. X-ray absorption was used to determine the density of the gel as a function of pressure, and the result yields an isothermal bulk modulus of 33 +/- 2 GPa. Brillouin spectroscopy was applied to measure isentropic bulk (24.9-34.0 GPa) and shear moduli (8.7-10.1 GPa) of the gel. The r...
Influence of degree of saturation on the borehole sealing performance of an expansive cement grout Akgün, Haluk (Elsevier BV, 2000-02-01) The strength measures of expansive cement grout borehole plugs cast in welded tuff cylinders is investigated as a function of the degree of saturation of the plugged rock cylinder and of borehole size. Details on experimental procedure regarding rock cylinder and cement grout preparation, sample curing conditions, experimental apparatus, sample loading, mechanical characterization of the rock, and cement grout, along with procedures for the determination of the sample saturation assuming uniform saturation,...
Prediction of damage in R/C shear panels subjected to reversed cyclic loading Hindi, R; Mansour, M; Dicleli, Murat (Informa UK Limited, 2005-01-01) In this paper, the damage prediction of shear-dominated reinforced concrete (RC) elements subjected to reversed cyclic shear is presented using an existing damage model. The damage model is primarily based on the monotonic energy dissipating capacity of structural elements before and after the application of reversed cyclic loading. Therefore, it could be universally applicable to different types of structural members, including shear-dominated RC members. The applicability of the damage model to shear-domi...
