| 摘要： | The study investigated the durability of high strength concrete at levels of 8, 10, and 12 ksi both with and without entrained air. Variables included air content, fly ash content, coarse aggregate type, cement and silica fume content, and type and length of curing. Testing performed included compressive strength, freeze-thaw resistance, rapid chloride ion permeability, deicer scaling resistance, chloride ion penetration, and microscopial air-void analysis. Testing indicates the need for entrained air in high strength concrete in order to render it freeze-thaw resistant. |
