The influence of the air-entraining agent (AEA) on a density, volume entrained air mortar mix and compressive strength hardened was studied in this article. Results show that addition AEA results reduction water to cement ratio provide targeted flow density depends air. causes decrease (C:S=1:2) by 8,2% increase 13,9% after 28 days hardening compared without AEA. further sand content (C:S=1:3) ...
