Calcium Carbide Testing – Why is it Never Done Correctly ...

 · The amount of gas produced is directly proportional to the amount of moisture present. It is widely accepted that a calcium carbide test of 5% or more confirms structural dampness. The Building Research Establishment Digest 245 states that this test should be taken from the most porous part of the wall (the mortar) and at the floor wall junction. However, time and again we see calcium carbide ...

Calcium Carbide Manufacturing

Calcium Carbide Manufacturing General Calcium carbide (CaC2) is manufactured by heating a lime and carbon mixture to 2000 to 2100°C (3632 to 3812°F) in an electric arc furnace. At those temperatures, the lime is reduced by carbon to calcium carbide and carbon monoxide (CO), according to the following reaction: CaO+3C→CaC2 +CO

Amphenol

Moisture measurements are made by mixing a weighed sample of the material with a calcium carbide reagent in the sealed pressure vessel. The reagent reacts chemically with water in the sample, producing acetylene gas that in turn increases the pressure within the vessel. As the pressure increase in the vessel is proportional to the amount of water in the sample, the moisture content can be read ...
