Using Aircrete for a sidewalk
I am concerned about the freeze/thaw here in Canada especially with this open cell architecture. Will this be a problem for me? Here in Canada sidewalks use a sulfate resistant concrete, is this necessary with Aircrete? Lastly because of the large amount of bubbles in the concrete is it necessary to seal the top of the concrete once it is poured?
Aircrete has similar qualities as concrete when it come to water. Water doesn't damage the material but it's recommended to use an exterior sealer to prevent moisture wicking into the surface.
AirCrete was developed in Sweden in the 1920s. It's used in cold climates around the world. Type II and V cement are sulfate resistant and can be used to make AirCrete.
