  2. Ultrasonic pulse velocity test - Wikipedia

    en.wikipedia.org/wiki/Ultrasonic_pulse_velocity_test

    An ultrasonic pulse velocity test is an in-situ, nondestructive test to check the quality of concrete and natural rocks. In this test, the strength and quality of concrete or rock is assessed by measuring the velocity of an ultrasonic pulse passing through a concrete structure or natural rock formation. This test is conducted by passing a pulse ...

  3. Sand equivalent test - Wikipedia

    en.wikipedia.org/wiki/Sand_equivalent_test

    A higher sand equivalent value indicates that there is less clay‐like material in a sample. During the test, material from the test specimen that can pass through a No. 4 sieve is mixed with solutions of calcium chloride, formaldehyde and glycerin in a cylinder. The content is then left for sedimentation. After about 20 minutes, the level of ...

  4. Flow table test - Wikipedia

    en.wikipedia.org/wiki/Flow_table_test

    The flow table test or slump-flow test is a method to determine consistency of fresh concrete. Flow table test is also used to identify transportable moisture limit of solid bulk cargoes. [ 1 ] It is used primarily for assessing concrete that is too fluid (workable) to be measured using the slump test , because the concrete will not retain its ...

  5. Water testing - Wikipedia

    en.wikipedia.org/wiki/Water_testing

    Water testing being conducted at a treatment facility in Broken Bow, Oklahoma. Water testing is a broad description for various procedures used to analyze water quality. Millions of water quality tests are carried out daily to fulfill regulatory requirements and to maintain safety. [1] Testing may be performed to evaluate:

  6. Permeability (foundry sand) - Wikipedia

    en.wikipedia.org/wiki/Permeability_(foundry_sand)

    Standard permeability meter. Permeability is a property of foundry sand with respect to how well the sand can vent, i.e. how well gases pass through the sand. And in other words, permeability is the property by which we can know the ability of material to transmit fluid/gases.

  7. Water flow test - Wikipedia

    en.wikipedia.org/wiki/Water_flow_test

    A set of three water pressure measurements are recorded from two hydrants. One hydrant is known as the residual hydrant or test hydrant and is located on or near the water main where a new water connection is desired. From this test hydrant, a static pressure and a residual pressure will be measured.

  9. Cone penetration test - Wikipedia

    en.wikipedia.org/wiki/Cone_penetration_test

    The cone penetration or cone penetrometer test (CPT) is a method used to determine the geotechnical engineering properties of soils and delineating soil stratigraphy. It was initially developed in the 1950s at the Dutch Laboratory for Soil Mechanics in Delft to investigate soft soils. Based on this history it has also been called the "Dutch ...
