The door member is preferably constructed of a gas-entrained cementitious material and has a compressive strength of at least about 30 lbf/in when measured using ASTM C-39. A method for forming a door member for use in construction with the door generally comprising: providing a door shell, placing the door shell in a fixture, filling the interior door cavity with a gas-entrained cementitious material, green-strength curing the gas-entrained cementitious material, and removing the door shell from the fixture is disclosed. The cured gas-entrained cementitious material provides a gas-entrained cementitious core for use in conjunction with a door.
