  2. 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 ...

  3. Concrete slump test - Wikipedia

    en.wikipedia.org/wiki/Concrete_slump_test

    The ASTM standards also regulate the rigidity of the cone. It states in the procedure that when the cone is removed, it should be lifted up vertically, without any rotational movement at all. [6] The concrete slump test is known as "Standard Test Method for Slump of Hydraulic-Cement Concrete" and carries the code (ASTM C 143) or (AASHTO T 119).

  4. Drainage - Wikipedia

    en.wikipedia.org/wiki/Drainage

    Drainage is the natural or artificial removal of a surface's water and sub-surface water from an area with excess water. The internal drainage of most agricultural soils can prevent severe waterlogging (anaerobic conditions that harm root growth), but many soils need artificial drainage to improve production or to manage water supplies.

  5. Water flow test - Wikipedia

    en.wikipedia.org/wiki/Water_flow_test

    A process to perform a water flow test is explained in the model fire codes as published by NFPA (National Fire Protection Association). If a water supply source is considered weak compared to what is required by the sprinkler system design hydraulic calculation , the water pressure can be boosted by means of a fire pump .

  6. Percolation test - Wikipedia

    en.wikipedia.org/wiki/Percolation_test

    A percolation test (colloquially called a perc test) is a test to determine the water absorption rate of soil (that is, its capacity for percolation) in preparation for the building of a septic drain field (leach field) or infiltration basin. [1] The results of a percolation test are required to design a septic system properly.

  7. Reduced pressure zone device - Wikipedia

    en.wikipedia.org/wiki/Reduced_pressure_zone_device

    The reduced pressure is guaranteed by a differential pressure relief valve, which automatically relieves excess pressure in the chamber by discharging to a drain. Four test cocks are installed to allow an inspector to verify proper operation of the valve with a differential pressure meter.

  8. Trench drain - Wikipedia

    en.wikipedia.org/wiki/Trench_drain

    A trench drain (also known as a channel drain, line drain, slot drain, linear drain, or strip drain) is a specific type of floor drain featuring a trough- or channel-shaped body. It is designed for the rapid evacuation of surface water or for the containment of utility lines or chemical spills.

  9. Foam Index - Wikipedia

    en.wikipedia.org/wiki/Foam_Index

    The Foam Index Test was developed to measure capacities of AEA for cement-mineral admixtures during concrete mixing. [ 2 ] The Foam Index Test is a laboratory titration procedure which determines the AEA absorption on fly ash or fly ash and cement mixtures.
