The invention discloses a ceramsite concrete insulating brick and a production method thereof. A brick block per cubic meter comprises the following components: ceramsite of 150-170kg, waste residue of 830-860kg, cement of 130-160kg, fly ash of 10-20kg and water of 120-130kg. The manufacturing method comprises the following steps: mixing the ceramsite and the waste residue to prepare a first mixture; mixing the cement and the fly ash to prepare a second mixture; mixing the first mixture and the second mixture, adding an appropriate amount of water, and mixing again; and forming through vibrating extrusion, stripping the mold and maintaining in an conventional way to obtain the ceramsite concrete insulating brick in the invention. The ceramsite can form a vitrified shell after firing formation, and the shell has good compressive strength, small shrinkage and good insulation properties. Since the waste residue is used as the main aggregate based on the ceramsite concrete, the weight proportion of the waste residue is 72 percent at least, the stacking density of the waste residue is 1100kg/m3, and the ceramsite concrete insulating brick is 30 percent lighter than other concrete porous bricks generally produced with limestone powder and other materials, the ceramsite concrete insulating brick of the invention has the advantages of low volume weight, small shrinkage, high compressive strength and good insulation properties.
