NBR NM 18 Cement Chemical Analysis Standard Test for Determination of Ignition Loss

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of NBR NM 18 testing. NBR NM 18 is a Brazilian technical standard that specifies the method for determining the ignition loss of cement. Ignition loss refers to the amount of material lost when a substance is heated to a high temperature. In the case of cement, ignition loss is a measure of the amount of carbonates and other volatile substances in the sample.

The method described in NBR NM 18 involves heating a cement sample in a furnace to a temperature of 900 to 1000 degrees Celsius until it is completely free of carbon dioxide and other volatile substances. The sample is then cooled and weighed, and the weight loss is calculated as a percentage of the original weight. This is the percentage ignition loss.

Determining the ignition loss is an important parameter for assessing cement quality as it can indicate the presence of impurities or contaminants in the sample. It is also used as a basis for calculating other important parameters such as the amount of free lime in the cement.

It should be noted that NBR NM 18 is specific to the Brazilian market and other countries may have different standards for determining ignition loss in cement. However, the general principles and methods described in the standard are widely used in industry and can be adapted to suit local requirements.
