In 1941, construction for the Schwerbelastungskörper began for the purpose of testing the load-bearing capacity of the ground on the planned site of Hitler's Triumphal Arch. [7] The Triumphal Arch was to be Hitler's focal point of Germania, therefore the Schwerbelastungskörper was a vital and necessary piece of construction. [1]
Testing the compressive strength of a concrete cube using Schmidt hammer Cross section. The hammer measures the rebound of a spring-loaded mass impacting against the surface of a sample. The test hammer hits the concrete at a defined energy. Its rebound is dependent on the hardness of the concrete and is measured by the test equipment.
The test is carried out using a metal mould in the shape of a conical frustum known as a slump cone or Abrams cone, that is open at both ends and has attached handles.The tool typically has an internal diameter of 100 millimetres (3.9 in) at the top and of 200 millimetres (7.9 in) at the bottom with a height of 305 millimetres (12.0 in).The cone is placed on a hard non-absorbent surface.
Compression testing of a concrete cylinder. The ingredients affect the strengths of the material. Concrete strength values are usually specified as the lower-bound compressive strength of either a cylindrical or cubic specimen as determined by standard test procedures. The strengths of concrete is dictated by its function.
Concrete is typically sampled while being placed, with testing protocols requiring that test samples be cured under laboratory conditions (standard cured). Additional samples may be field cured (non-standard) for the purpose of early 'stripping' strengths, that is, form removal, evaluation of curing, etc. but the standard cured cylinders ...
Cubic or cylindrical samples of concrete are tested under a compression testing machine to measure this value. Test requirements vary by country based on their differing design codes. Use of a Compressometer is common. As per Indian codes, compressive strength of concrete is defined as: Field cured concrete in cubic steel molds (Greece)
Duff A. Abrams (1880–1965) was an American researcher in the field of composition and properties of concrete. He developed the basic methods for testing concrete characteristics that remain in use. A professor with the Lewis Institute, he studied the component materials of concrete in the early 20th century.
A concrete cylinder being tested under a UTM. The set-up and usage are detailed in a test method, often published by a standards organization. This specifies the sample preparation, fixturing, gauge length (the length which is under study or observation), analysis, etc.
