. Non-asphaltic designed to meet stringent fire code requirements. Start molding strength specimens within 15 minutes after obtaining the composite sample. Composite sample must be at least 1 cubic foot of concrete.

Fine aggregate content is usually 35 to 45 by. Air-entrained concrete is produced using air-entraining Portland Cement or by the introduction of air-entraining agents under careful engineering supervision as the concrete is mixed on the job. The amount of entrained air is usually between four and seven percent of the volume of the concretebut may be varied as required by special conditions.
