The invention relates to the technical field of cement boards, especially to a composite foamed cement board, which includes: a first foamed cement board, a second foamed cement board and a third foamed cement board. The first foamed cement board and the second foamed cement board are in fixed connection through a binder layer, the second foamed cement board and the third foamed cement board are in fixed connection through a binder layer, the upper surface of the first foamed cement board and the lower surface of the third foamed cement board are coated with a facing mortar layer, and a radiation absorption layer is disposed between the facing mortar layers. According to the invention, an interlayer is disposed between two layers of foamed cement boards, and the interlayer has the structure of an anti-cracking material, so that the foamed cement board has reinforced strength and good toughness, is difficult to break, and has good thermal insulation performance, can greatly reduce the heating and cooling and other electric power and burning expenses, thus being the optimal choice of energy saving.
