Tensile testing, also known as tension testing, [1] is a fundamental materials science and engineering test in which a sample is subjected to a controlled tension until failure. Properties that are directly measured via a tensile test are ultimate tensile strength, breaking strength, maximum .
Tensile strength is one of the important mechanical properties of concrete, but it is difficult to measure accurately due to the brittle nature of concrete in tension. The three widely used test methods for measuring the tensile strength of concrete each have their shortcomings: the direct tension test equipment is not easy to set up, particularly for alignment, and there .
The study aims to develop a new approach of concrete tensile strength test characteristic by minimizing the traditional drawbacks such as load eccentricity, stress or strain non-uniformity and stress concentration in traditional test methods and of a distinguished gauge region which undergoes uniform tensile stress so the determination of the tensile stress .
Keywords: compression test; tensile strength; test. DOI: 10.14359/10162. Date: 1/1/2001. Abstract: The measured tensile strength of concrete is dependent on the test method used. Compared with indirect methods, the direct tension test method gives results closer to the true tensile strength under pure tension condition.
The tensile Testing method measures the force required to break a metallic, composite, or plastic specimen and the extent to which the specimen stretches or elongates to that breaking point. Tensile Test Procedure. A tensile specimen of standard dimensions machined from the metal is inserted in a tensile testing machine (shown in the below figure).5. Age of the Concrete at the Time of Testing: The increase in tensile strength after one month is slower than the compressive strength. Hence the age of specimen affects this ratio. 6. Methods of Testing: Tensile strength is determined by the following methods: (a) Direct tension method. (b) Splitting tension method. (c) Flexural tension method. 3.1 Test Setup. In previous investigations at the Institute of Building Materials Research (ibac), the tensile test method based on ASTM C307-03 on small “bone-shaped specimens” yielded a low scattering of the tensile strength of cement based mortars with a high ratio of evaluable results.On the basis of these examinations the test apparatus according to .
