  — Keywords Loss on ignition Doggerland sediment Thermogravimetric analysis Multistage Introduction Loss on ignition LOI Heating of samples to specified temperatures has been used widely to measure organic matter and carbonate content in sediment soil and coal fly ash samples Bengtsson and Enell 1986; Heiri et al 2001;

  Rapid detection of loss on ignition for unburned carbon powder in fly

  — The unburnt carbon content in fly ash can be represented by the LOI For LOI testing of fly ash triboelectric separation recycled products there are 4 problems with traditional detection methods Firstly the oxygen concentration during combustion will affect whether the combustion of fly ash is complete [14]

  Variables Affecting the ASTM Standard C 311 Loss on Ignition

  — 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

  Evaluation of activated high volume fly ash systems using

  — The reference fly ash low loss on ignition did not perform better than the high LOI ashes as expected The effect of the Fe 2 O 3 content is highly relevant to the activation process but remains poorly understood; this appears to reduce the speed of dissolution of the reactive components of fly ash

  Characterization of supplementary cementitious materials by

  — The loss on ignition of fly ash is often used as a measure of the content of unburnt carbon in the material [7 8] as the carbon can oxidize during heating in the presence of oxygen to CO and CO 2 which is released during TGA measurement [9 10] Any moisture content in the fly ash residual water from storage will also register

  Dry beneficiation of high loss on ignition fly ash

  — Dry beneficiation of three high loss on ignition LOI fly ashes were conducted The combination of two different types of dry separation techniques—ultrasonic sieving and triboelectrostatic separation—were used for this study The results indicate that a simple separation of unburned carbon from fly ash is achievable at particle sizes
