EFFECT OF PARTIAL REPLACEMENT OF FINE AGGREGATES

ABSTRACT

Despite the fact that sand is often non-toxic, operations like sandblasting call for safety measures. The labels on silica sand bags used for sandblasting now warn users to use respiratory protection to prevent breathing in the tiny silica dust that results from the process.According to the safety data sheets for silica sand, "excessive inhalation of crystalline silica is a serious health concern"Archived at the Wayback Machine on March 11, 2006.
