AS 1012.12.1:1998 (R2014) PDF Download

AS 1012.12.1:1998 (R2014) is a standard that provides a rapid method for determining the mass per unit volume of hardened concrete. The method is applicable to regular shaped specimens with minimal defects, as well as capped specimens as long as the mass per unit volume of the cap does not differ from that of the specimen by more than 25 percent.

It is recommended that the mass per unit volume of concrete be based on the average value obtained from a group of at least two representative specimens, as there may be variations in results. The standard also includes notes on general procedures and precautions for laboratory operations to ensure the safety of individuals and property. Additionally, the standard notes that the testing procedure may involve hazardous materials, operations, and equipment, highlighting the importance of following safety guidelines and protocols.
