tension and compression testing machine
Concrete Compression Testing Machines are specialized equipment to evaluate the compressive strength of concrete (tensile strength of concrete) which is measured in pounds per square inch (psi). These machines apply controlled increasing force to a concrete sample until it breaks and determine its maximum strength.Compression testing is one of the most fundamental types of mechanical testing, alongside tensile and flexion tests. Compression tests are used to determine a material’s behavior under applied crushing loads, and are typically conducted by applying compressive pressure to a test specimen (usually of either a cuboid or cylindrical geometry) using platens or specialized .A universal testing machine (UTM), also known as a universal tester, [1] universal tensile machine, materials testing machine, materials test frame, is used to test the tensile strength (pulling) and compressive strength (pushing), flexural strength, bending, shear, hardness, and torsion testing, providing valuable data for designing and . Hydraulic machines, composed of single or dual column frames, a load cell, and testing software, can measure compression strength, yield strength, modulus of elasticity, and deformation behavior. Servo-electric machines, on the other hand, use electric motors for force application, offering higher accuracy, precision, and energy efficiency.
The standard is designed for testing the strength of cylindrical concrete specimens, which include molded cylinders and drilled cores. The procedure outlined entails the determination of the compressive strength of these specimens. As for the equipment, it includes compression testing machines that meet or exceed ASTM C39 requirements. The .The Universal Testing Machine (UTM), also known as a Universal Tester, Materials Testing Machine, or Tensile Testing Machine, is a versatile piece of equipment that can perform multiple types of mechanical tests, including compression tests. The UTM is designed to test the tensile strength and compressive strength of materials.
Procedure: Compressive Strength Test of Concrete Cubes. . These specimens are tested by compression testing machine after seven days curing or 28 days curing. Load should be applied gradually at the rate of 140 kg/cm2 per minute till the Specimens fails. Load at the failure divided by area of specimen gives the compressive strength of concrete.
Step 2: Know Your Sample Types and Strength Requirements The size of specimens tested directly influences the maximum concrete strength the machine is capable of testing. For instance, following the guidelines indicated above, a compression machine with a total capacity of 250,000lbf can test 6x12in cylinders with expected strengths up to about 7,000psi.A Universal Testing Machine (UTM), also known as a tensile testing machine/tester, is an electromechanical testing system that applies a tensile force to raw materials or components to test for both tensile and compressive strength. It is widely used for both small and large load testing in quality control or research projects, etc. ASTM C39, Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens, specifies that the loading rate fall within 0.14 to 0.34 MPa/sec (20 to 50 psi/sec). On average, the compressive strength of cylinders tested at the high load rate limit will be 3% greater than cylinders tested at the low load rate limit.
Compressive strength testing of concrete:-The test is carried out using 150mm concrete cubes on a Universal testing machine or compressive testing machine. Apparatus. As per IS: 516-1959 Compressive testing machine (2000Kn),15cm×15cm×15cm steel cube molds or Cylinder having Dia 15cm and length 30cm are used. The test includes following steps:-A compression test is one of the most fundamental mechanical tests that can be performed on a material, product, or component. Our compression test machines measure characteristics such as yield strength, ultimate strength, .
To operate a compression testing machine, place the cube in the machine and apply pressure until it fails. Using a compression testing machine designed for this purpose ensures accurate and reliable results. Test Process. During testing, the compression testing machine applies pressure to the cube at a rate of 140 kg/cm² per minute until it fails. Testing: The cured samples are placed in a compression-testing machine. Load Application : A load is applied gradually at a constant rate until the sample fails. Result Recording : The maximum load at failure is recorded, and the compressive strength is calculated by dividing this load by the cross-sectional area of the sample.
