Background

Terrazzo is widely used in the construction industry for paving exterior walls or floors of buildings, etc. The terrazzo is made up by mixing stone rice, sand stone and cement, and is spread on the external wall of building, after the cement is solidified, the surface sludge can be removed by water. The mud washed off by the cleaning wall surface is discharged into a sewer in a large amount, and is very dirty, so that the sewer is blocked, and the environment is seriously polluted. Moreover, the stone rice surface is sharp and protruded, so that the skin is easily scratched, and the cleaning is very inconvenient. Thus, despite the simplicity and low cost of the terrazzo manufacturing process, this approach has been increasingly used.

In addition, the terrazzo is easy to crack after years of use, and the crack formation causes are multiple: combine not strong between common terrazzo layer and the original bottom plate, break away from with original bottom plate under the long-term external stress, the department of breaking away from is not smooth surface, even be vertical decurrent stress effect down also can bear shear stress at the part, make the terrazzo fracture, again if the terrazzo reduces the tensile stress that shrink or inflation volume deformation brought through slotting, but embellishment such as metal strip can be installed to the department at the cutting seam simultaneously, the embellishment is metal material usually, will make the terrazzo of metal strip both sides bear compressive stress when the people walk and step on the pressure metal strip, and in the long term, can lead to the terrazzo to begin the fracture from the department of slotting. In addition, maintenance is not standardized, or heavy weight can also cause the terrazzo to crack.
