About
This article is about a NIOSH study to develop a practical method of measuring shotcrete early strength onsite in the first six hours after application using a partial beam test standard, ASTM C 116-90. A more thorough understanding of shotcrete early strength will lead to improvements in ground support practices, thereby preventing ground falls and reducing mine roof-fall accidents.
