Tensile strength of concrete is measured bya)Direct tension test in th...
Tensile strength of concrete is measured by applying compressive load along the diameter of the cylinder. This is known as the split cylinder test or Brazilian test. This test is performed by preparing a cylinder specimen of concrete and then loading it diametrically until it splits apart. The tensile strength of the concrete is calculated based on the maximum load applied before the cylinder splits.
The process of measuring the tensile strength of concrete using the split cylinder test involves the following steps:
1. Preparation of the specimen: A cylindrical specimen of concrete is prepared with a diameter of 150 mm and a height of 300 mm. The ends of the cylinder are then ground flat and parallel.
2. Loading the specimen: The specimen is placed horizontally on the lower bearing block of the testing machine. A compressive load is applied to the specimen along the diameter at a rate of 0.2 MPa per second until it splits apart.
3. Calculation of tensile strength: The tensile strength of the concrete is calculated using the formula T = 2P/πD^2, where T is the tensile strength, P is the maximum load applied before splitting, and D is the diameter of the cylinder.
The split cylinder test is widely used to determine the tensile strength of concrete because it is a simple and reliable method. It is also a non-destructive test, which means that the specimen can be reused for other tests. However, it is important to note that the tensile strength of concrete is typically much lower than its compressive strength, which is why the split cylinder test is not as commonly used as other tests such as the compressive strength test.
