Civil engineering testing equipment are used in the quality control processes associated with the analysis of soils, concrete, asphalt, bitumen, cement and mortar, steel, aggregates, and other materials used in civil engineering.
Concrete Materials testing equipments breaks down into five major categories: mechanical testing; testing for thermal properties; testing for electrical properties; testing for resistance to corrosion, radiation, and biological deterioration; and nondestructive testing by concrete testing lab equipment.
Materials testing is a respected and established technique which is used to ascertain both the physical and mechanical properties of raw materials and components. It can be used to examine almost anything from human hair to steel, ceramics or composite materials.
Tensile test. A standard specimen is subjected to a gradually increasing load (force) until failure occurs. The resultant load-displacement behaviour is used to determine a stress–strain curve, from which a number of mechanical properties can be measured.
Compression testing used for test of concrete in civil engineering is a very common testing method that is used to establish the compressive force or crush resistance of a material and the ability of the material to recover after a specified compressive force is applied and even held over a defined period of time. Compression tests are used in civil engineering to determine the material behaviour under a load. The maximum stress a material can sustain over a period under a load (constant or progressive) is determined.
Compression testing is often done to a break (rupture) or to a limit. When the test is performed to a break, break detection can be defined depending on the type of material being tested. When the test is performed to a limit, either a load limit or deflection limit is used.
Common compression testing results are:
– Load at Rupture
– Deflection at Rupture
– Work at Rupture
– Maximum Load
– Deflection at Maximum Load
– Work at Maximum Load
– Chord Slope
– Offset Yield
Generally, there are two types of bending tests: 3-point bend and 4-point bend. The materials that are tested using the flex test method vary from metal, plastic, wood, laminates, particle board, dry wall, ceramic tile to glass. Bending tests vary greatly based on the product being tested.
There are a variety of industry standards that we manufacture, supply, trade and export in India and Global market which are mostly based on the sample material under test. Bending tests generally involve the measurement of ductility of a sample material. Bending tests may involve taking the sample material to a specific limit and determining the load measurement and its relationship to a load specification (pass/fail). Or, it may involve bending a material until the material experiences a break and determining both the load and deflection required to initiative the break limit.
