Effect of volcanic ash on the properties of cement paste

2011-11-1  Volcanic ash (VA) is formed during volcanic eruptions. Volcanic glass is relatively high in silica, and its physical and chemical properties could be referenced with ASTM C618-93, a Standard Specification for ‘Fly Ash and Raw or Calcinated Natural Pozzolan for Use as a Mineral Admixture in Portland Cement Concrete’.

Properties of concrete made with volcanic ash

2012-9-1  Volcanic ash (VA) is formed during volcanic eruptions, and is considered as natural pozzolan as per ASTM C618-93, a standard specification for ‘Fly Ash and Raw or Calcinated Natural Pozzolan for Use as a Mineral Admixture in Portland Cement Concrete’.It can be suitably used in cement, mortar, and concrete.
