Calcium Carbide Moisture Test - The Screed Scientist®

Calcium Carbide Moisture Test. Overview. The calcium carbide method is one of the most accurate and reliable methods of moisture testing, as the results do not just indicate the moisture levels for the surface of the screed, but it also provides an accurate measurement of the moisture present in the screed to a depth of up to 50% of its thickness.

Calcium Carbide – Structure, Production, Uses and FAQs

Calcium carbide is industrially produced in an electric arc furnace with a mixture of coke and lime, approximately at 2,200 °C (3,990 °F). This is an endothermic reaction that requires a high temperature to drive off the carbon monoxide at 110 kilocalories (460 kJ) per mole. Since its invention in 1892, this method has not changed.
