There are many reasons for cracking of Terrazzo floor. Let's analyze them one by one:
1. During construction, if the base floor is not cleaned thoroughly, and the joints and end joints of the prefabricated concrete floor are not poured tightly, it will affect the integrity and stiffness of the floor. When the ground load is too concentrated, it will cause cracks.
2. During construction, in order to catch up with the construction period, the structural settlement is unstable, the cushion and surface processes are closely followed, the cushion material shrinkage is unstable, the concealed cable pipelines are too high, and the surrounding mortar is not well fixed, resulting in surface cracks.
3. The other reason is that the ground backfill is not solid, the surface height has a drop, and the thickness of the cushion is uneven or too thin, which will cause cracks in the Terrazzo floor.
