Concrete Exposure Classes

TECHNICAL SPECIFICATIONS Concrete Exposure Classes Determination of the minimum Concrete performance properties is based upon identifying the following key requirements: Applicable Exposure Conditions The designer must assess the environmental conditions that the Concrete will be exposed to during its service life. Direct input is also required from the owner regarding possible future uses since they can significantly affect the Exposure class selection. Structural Requirements The designer must determine the minimum Concrete properties required to meet the applicable loading conditions.

Concrete exposed to freezing and thawing in a saturated condition but not to chlorides. Examples: pool decks, patios, tennis courts, freshwater pools, and freshwater control structures. F-2 . ... aggregate, % 10 mm . 14 – 20 mm .

Architectural precast concrete has been used since the early 20th century, coming into wide use in the 1960s. The versatility of precast concrete makes it ideal for architectural applications. The exterior surface of a precast concrete piece can vary from a form face finish similar to cast-in-place to an exposed aggregate

Exposed to cycles of freezing and thawing with the same degree of exposure to water as Exposure Class F2. AddiBonally, concrete in Exposure Class F3 is anBcipated to be exposed to deicing chemicals. Deicing chemicals can increase water absorpBon and retenBon (Spragg et al. 2011), which would enable the concrete to become saturated more readily.

Concrete can resist the effects of one freeze-thaw cycle as long as it is properly air-entrained, not exposed to an external water source, and has reached a COMPRESSIVE STRENGTH OF 500 psi. For well- proportioned concrete mixtures, this is typically within 48 hours of placement when the concrete temperature is maintained at 50 °F. 01
