Effect of LOI of fly ash on properties of concrete
Generally, the amount of unburned carbon of fly ash can be easily determined by the LOI test (ASTM D7348) High LOI fly ash is generally known to cause some malfunctions in concrete, The European fly ash standard (EN 4501) provides a specification limit on soundness for fly ashes containing >15% CaO When ASTM C618 was originally adopted, it appears that the ASTM C618 Fly Ash Specification: Comparison with Other GaleTo control carbon content, ASTM Standard C 61803 4 limits loss on ignition LOI of fly ash to 60 percent by mass Although LOI is a standard index for carbon content of ash, LOI andVariables Affecting the ASTM Standard C 311 Loss on Ignition Test 2021年1月1日 Keywords: fly ash; loss on ignition; specifications; standards; strength activity index DOI: 1014359/ Date: 1/1/2021 Abstract: ASTM C618 and AASHTO M 295 ASTM C618 Fly Ash Specification: Comparison with Other
