[1112] EFFECT OF MIX DESIGN AND CURING CONDITION ON TRAPPED AIR BUBBLES DURING WATER PERMEATION
キーワード：air bubbles、cement paste、mix design、mortar、penetration depth、porosity、water permeation
During liquid water permeation into concrete, air trapping occurs and may affect water mass transport. To determine the relationship between the amount of trapped air bubbles, mix design, and curing condition, water absorption tests of different mortar and cement paste mixtures with different air-entrainment agent usage, water to cement ratios, fly ash/blast furnace slag proportions, and curing were conducted under decompression and atmospheric conditions. Air trapping estimates were affected by mix design and curing condition, but not directly correlated with porosity.
