Air-Entraining Concrete
When DuraCrete is used in combination with air entrainers during concrete production:
2% DuraCrete content reduces radius of air pores by 11%.
4% DuraCrete content reduces radius of air pores by 22%.
However, the total volume of air pores is the same for untreated concrete offset with DuraCrete. The number of air pores with a reduced radius actually increases. The greater number of air pores are more consistently distributed in the concrete.
DuraCrete in combination with an air-entraining agent reduces the radius of air pores. The reduction of the radius is proportional to the amount of DuraCrete applied.
2% DuraCrete = 11% radius reduction.
4% DuraCrete = 22% radius reduction.
The air pore volume is the same, but the number of air pores increases.
An increase in the number of air pores in the concrete improves resistance against the destructive influence of frost-thaw-changes and increase de-icing resistance.
