  2. Janka hardness test - Wikipedia

    en.wikipedia.org/wiki/Janka_hardness_test

    For hardwood flooring, the test usually requires an 80 mm × 150 mm (3 in × 6 in) sample with a thickness of at least 6–8 mm, and the most commonly used test is the ASTM D1037. When testing wood in lumber form, the Janka test is always carried out on wood from the tree trunk (known as the heartwood), and the standard sample (according to ...

    en.wikipedia.org/wiki/File:Concrete_Durability...

    English: The "Bache method" for testing concrete durability, which simulates daily temperature variations in brine. Test 1 or 2 (each 24 h) may be used, or both performed sequentially during a 48-hour period. The chosen cycle is repeated ad nauseam in order to determine the mass-loss, as an analogue for durability.

  5. Cement - Wikipedia

    en.wikipedia.org/wiki/Cement

    Sorel cement is a hard, durable cement made by combining magnesium oxide and a magnesium chloride solution Fiber mesh cement or fiber reinforced concrete is cement that is made up of fibrous materials like synthetic fibers, glass fibers, natural fibers, and steel fibers. This type of mesh is distributed evenly throughout the wet concrete.

  6. Schmidt hammer - Wikipedia

    en.wikipedia.org/wiki/Schmidt_hammer

    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. By reference to a conversion chart, the rebound value can be used to determine the concrete's compressive strength. When conducting the test, the hammer should be held at right angles to the ...

  7. Gypsum concrete - Wikipedia

    en.wikipedia.org/wiki/Gypsum_concrete

    Gypsum concrete is a building material used as a floor underlayment used in wood-frame and concrete construction for fire ratings, sound reduction, radiant heating, and floor leveling. [1] It is a mixture of gypsum plaster, Portland cement , and sand .

  8. Thermal integrity profiling - Wikipedia

    en.wikipedia.org/wiki/Thermal_integrity_profiling

    Thermal Integrity Profiling (TIP) is a non-destructive testing method used to evaluate the integrity of concrete foundations. It is standardized by ASTM D7949 - Standard Test Methods for Thermal Integrity Profiling of Concrete Deep Foundations. The testing method was first developed in the mid 1990s at the University of South Florida.

  9. Reinforced concrete structures durability - Wikipedia

    en.wikipedia.org/wiki/Reinforced_concrete...

    To assess some of the durability design parameters, the use of accelerated laboratory test is suggested, such as the so called Rapid Chloride Migration Test to evaluate chloride penetration resistance of concrete [11] '. Through the application of corrective parameters, the long-term behaviour of the structure in real exposure conditions may be ...
