Lightweight porous ceramsite concrete brick

The utility model provides a light porous ceramsite concrete brick. Brick main body, the brick main body takes a transverse symmetry axis of the upper end surface of the brick as an axis; two trapezoidal grooves are symmetrically formed; the two symmetrically-arranged trapezoidal grooves are connected through a circular hole groove. Two sides of the circular hole groove are communicated with the outer edge of the brick body; the structure plays a role in buffering and slowly releasing the absorption of attached moisture and harmful substances; the trapezoidal grooves and the circular hole grooves are formed in the brick body and slowly extend to the middle of the brick body from the edge of the brick body to achieve multi-layer adsorption and absorption, the trapezoidal grooves and the circular hole grooves are filled with the light porous ceramsite formed by bonding the metal tailings and the nonmetallic minerals, the brick body is light in weight, and various air pollution and harmful impurities can be effe
