Environmental-friendly foam concrete blocks

The invention provides environmental-friendly foam concrete blocks, and belongs to the field of building materials. One cubic meter of the environmental-friendly foam concrete blocks comprises following raw materials: 280 to 300 kg of cement, 80 to 120 kg of fly ash, 100 to 120 kg of building rubbish, 185 kg of water, 15 to 17 kg of a foaming agent aqueous solution with a concentration of 10%, and 0.9 kg of a foam stabilizer water solution with a concentration of 10%. The environmental-friendly foam concrete blocks are prepared via stirring, foaming, moulding, cutting, and air drying and condensing. Waste materials such as fly ash and building rubbish are used for preparing the environmental-friendly foam concrete blocks, and calcining is not needed, so that the environmental-friendly foam concrete blocks are capable of saving energy better and are more friendly to the environment.
