This allows concrete to be placed in winter with reduced risk of frost damage. Concrete is damaged if it does not reach a strength of 500 pounds per square inch (3.4 MPa) before freezing. Typical chemicals used for acceleration today are calcium nitrate (Ca(NO3)2), calcium nitrite (Ca(NO2)2), calcium formate (Ca(HCOO
