Blind-hole air brick

The invention discloses a blind-hole air brick. The blind-hole air brick comprises a brick body, wherein a plurality of cavities are formed in the brick body; each cavity extends from one end to the other end of the interior of the brick body; an end surface plate is arranged at one end of the brick body, so that all the cavities become blind holes; air holes are formed in the end surface plate and correspond to the cavities; the end surface plate concaves to form a mortar filling groove; a plurality of strip-shaped through grooves are formed in the outer surface of each of the upper wall, the lower wall, the left wall and the right wall at equal intervals; the outer surface of the brick body can be glazed. The blind-hole air brick has the benefits that during brick laying, as the blind holes are formed in one end, mortar leakage is prevented, the mortar consumption is reduced and the brick laying stability is improved; a sawtoothed filling layer can be formed between the upper-layer brick body and the lower-layer brick body through the strip-shaped through grooves, so that the fastness degree of connection between the brick bodies is improved; the air holes are reserved in one ends of the blind holes to achieve ventilation during roasting so as to prevent cracks; after the outer surface of the blind-hole air brick is glazed, the smoothness degree is high and a decorating role can be played.
