Preparation method of carbon dioxide ceramsite foamed concrete

The invention belongs to the technical field of concrete, and relates to a preparation method of carbon dioxide ceramsite foamed concrete. According to the invention, the ready-made carbon dioxide gas is introduced into the foaming agent solution by using a foaming machine, so that foam filled with the carbon dioxide gas is formed, and then the foam is added into the stirred ceramsite concrete and is fully stirred and mixed again, so that the carbon dioxide ceramsite foamed concrete is formed and has an excellent heat insulation effect; the ceramsite has good high temperature resistance, moisture absorption performance, hardness and stability, and the ceramsite is doped as a lightweight aggregate, so that the concrete has higher fire resistance, compressive strength and bending strength than common foamed concrete while keeping light weight, and has certain adaptability to environments with high humidity; therefore, the structure is more suitable for occasions requiring higher structural strength. 本发明属于混凝土技术领
