    Abstract

    The loss on ignition (LOI) test as an indicator of carbon content in fly ash is a useful screening tool for fly ash for use in concrete. Despite the importance and relevance of the LOI test, the LOI test results are sensitive to procedural variations that are within the requirements of the ASTM C 311 test standard. A suite of LOI tests on fly ash samples was performed that varied several procedural details. The effects of cooling time, cooling method, sample size, ignition duration, and ignition temperature were evaluated.
