Effect of crushed ceramic and basaltic pumice as fine ...

2007-6-1  The main objective of this investigation is to study the performance of concrete with ceramic waste and crushed basaltic pumice fine aggregate. Two sources of fine aggregate replacement were used in this work. Crushed ceramic and crushed basaltic pumice source were used at three levels of fine aggregate cement replacements (40%, 50%, and 60%).

Pumice: Igneous Rock - Pictures, Definition More

Pumice is produced in two forms: rock pumice and pumicite. "Pumicite" is a name given to very fine-grained pumice (less than 4 millimeters in diameter down to submillimeter sizes). The word can be used synonymously with "volcanic ash." It is mined from volcanic ash
