The Seattle Concrete Lab is actively involved in Sustainable Development on both a local and global scale. We perform mix designs and run trial mixes to investigate the use of recycled concrete in future construction. Testing is also being done to support the use of recycled supplementary cementicious materials such as Fly Ash and NewCem throughout the region while investigating the future of recycled material. Lafarge is convinced that sustained economic growth cannot occur without social progress, environmental protection and respect for local communities.

The relative density specific gravity , a dimensionless quality, is expressed as oven-dry OD , saturated-surface-dry SSD , or as apparent relative density specific gravity. The OD relative density is determined after drying the aggregate. The SSD relative density and absorption are determined after soaking the aggregate in water for a prescribed duration. This test method is not intended to be used for lightweight aggregates that comply with Specification C Group I aggregates.
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. The text of this test method references notes and footnotes that provide explanatory material.
These notes and footnotes excluding those in tables and figures shall not be considered as requirements of this test method. This standard does not purport to address all of the safety concerns, if any, associated with its use.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
