2. Concrete moisture meter - Wikipedia

   en.wikipedia.org/wiki/Concrete_moisture_meter

   There is no ASTM standard for using a concrete moisture meter to determine a final moisture content reading. Concrete moisture meters, [4] either non-pin or pin meters are affected by what it sees in the concrete. This can be anything from the density of the concrete and aggregate size to the chemical properties of the slab.

3. Epoxy moisture control system - Wikipedia

   en.wikipedia.org/wiki/Epoxy_moisture_control_system

   There are two industry standards for measuring moisture vapor emissions in concrete: calcium chloride testing (ASTM F1869) and relative humidity testing (ASTM F2170). [3] Epoxy moisture control systems can be used when these tests determine that the moisture vapor emissions need to be remediated in order to install the selected floor covering ...

4. Alkali–silica reaction - Wikipedia

   en.wikipedia.org/wiki/Alkali–silica_reaction

   ASTM C1293: "Test Method for Concrete Aggregates by Determination of Length Change of Concrete Due to Alkali-Silica Reaction". It is a long-term confirmation test (1 or 2 years) at 38 °C in a water-saturated moist atmosphere (inside a thermostated oven) with concrete prisms containing the aggregates to be characterised mixed with a high-alkali ...

5. Sand equivalent test - Wikipedia

   en.wikipedia.org/wiki/Sand_equivalent_test

   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 clay suspension and the sand level is read on the cylinder scale.

6. Bresle method - Wikipedia

   en.wikipedia.org/wiki/Bresle_method

   The solubility in water depends on the type of salt. Sodium chloride can be dissolved in cold water to a concentration of 357 g∙l −1. Not only solubility differs between salts but also the conductivity. When performing a Bresle method test, not only sodium chloride is dissolved but also all other salts present on the surface.

7. Calcium chloride - Wikipedia

   en.wikipedia.org/wiki/Calcium_chloride

   Calcium chloride was apparently discovered in the 15th century but wasn't studied properly until the 18th century. [11] It was historically called "fixed sal ammoniac" (Latin: sal ammoniacum fixum [12]) because it was synthesized during the distillation of ammonium chloride with lime and was nonvolatile (while the former appeared to sublime); in more modern times (18th-19th cc.) it was called ...
