General description: Air content is measured by a pressure meter method. Air content in mortar affects compressive strength, bond strength and workability of the mortar. Limits imposed on the percent air by volume of mortar are a maximum of 12% for portland-cement lime mortars and 18% for masonry cement mortars. MSJC - Masonry Standard Joint Committee |
