ACI ASTM C138 ASTM C138 is utilized to determine the density (unit weight), yield, and air content (gravimetric) of concrete. A decrease in density may suggest several possibilities, including changes in materials (lower specific gravity), increased water content, higher air content, alterations in ingredient proportions, or reduced cement content. If the reduction in concrete density is attributed to an increase in air content, it may enhance the concrete's durability against fre...
