ACI ASTM C138 Latest Version with Complete Solutions ASTM C138 is used for what test method for Density(unit weight), Yield, and Air Content(gravimetric) of concrete A lower density may indicate what 1)materials have changed[lower specific gravity], 2)higher water content, 3)higher air content, 4)a change in proportions of ingredients, and/or 5)lower cement content. If a reduction of the density of the concrete was due to an increase in air content what can be expected the concre...
