Detection of Concrete Damage Using Ultrasonic Pulse Velocity Method
This paper investigates the efficiency of Ultrasonic Pulse Velocity (UPV) method in detecting cracks and flaws inside the concrete. A series of concrete beams and slab specimens were cast and damaged to simulate the different mechanisms possible in a reinforced concrete deck due to mechanical loading. Two types of simulated cracks, namely, cracks perpendicular and cracks parallel to axis of bea...
متن کاملEstimation of mechanical and durability properties of self-compacting concrete with fibers using ultrasonic pulse velocity
In this research, the performance of ultrasonic pulse velocity (UPV) in concrete is examined as a nondestructive experiment in order to estimate mechanical (compressive and tensile strength) and durability (water absorption) properties of fiber-reinforced self-compacted concrete For this purpose 11 mixture designs containing 3 types of fibers (steel: 0.1, 0.2, 0.3 and 0.4 percent by volume, Pol...
متن کاملExperimental study of impact strength and modulus of elasticity of reinforced concrete under ambient temperature, used in concrete dams
The choice of concrete consumption and high strength in the structure of concrete dams is of particular importance. In this laboratory research, slag alkaline concrete containing 0, 4 and 8% nanosilica and 1 and 2% polyolefin fibers has been produced in 5 mixing designs. A design of control concrete containing Portland cement was prepared to compare with the test results of reinforced concre...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولEvaluation of Modulus of Elasticity of Laminated Strand Lumber by Non-Destructive Evaluation Technique
Non-destructive evaluation (NDE) techniques have been shown to be effective for evaluating mechanical properties of wood-based materials. In this study, transverse vibration of a beam under the two ends free boundary condition (FBV) was employed to measure the modulus of elasticity (MOE) in different strength directions of laminated strand lumber (LSL). It was found that the MOE values measured...
