Slagbrick is a new kind of hydraulic construction material. It has some evident advantages, such as large strength, strong frost-resisting, low cost and beneficial to protect environment.
矿渣砖是一种新型的水工建筑材料，它具有强度大、抗冻性强、成本低、利于环保等特点。

When the reaction products form as high melting point CA2, CA6 and MA spinel in a continuous solid phase it will clog the liquid channel and resist the further diffusion of fused slag in the brick.
The shortcoming of current slag cavity brick is presented . Its size is determined. The action of production method and gap ratio on its strength is studied in this paper.
