AASHTO T 356 - STANDARD METHOD OF TEST FOR DETERMINING AIR CONTENT OF HARDENED PORTLAND CEMENT CONCRETE BY HIGH-PRESSURE AIR METER Organization: AASHTO
Date: 2015-01-01
Description: This test method covers laboratory determination of the air content of hardened portland cement concrete with the use of the high-pressure air meter. This determination is made from the observation of change in linear piston movement with a specimen in the test chamber from that of the linear piston movement with no specimen in the test chamber.
ACI 234R - GUIDE FOR THE USE OF SILICA FUME IN CONCRETE Organization: ACI
Date: 2006-01-01
Description: Initial use of silica fume in concrete was mostly for cement replacement, along with water-reducing admixtures (WRAs). Eventually, the availability of high-range water-reducing admixtures (HRWRAs, often referred to as superplasticizers) allowed new possibilities for the use of silica fume to produce high levels of performance.
