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’.This paper presents comprehensive details of the physical, chemical properties of volcanic ash, and its micro-structure and hydration products. It also covers effect of volcanic ash on consistency, setting times, workability, compressive strength, electrical resistivity of cement paste and mortar.
► This paper discusses volcanic ash in cement paste and mortar. ► Presents properties of volcanic ash and applications of volcanic ash. ► Effect of volcanic ash on the fresh, strength, and durability properties of cement paste and mortar.
