The ceramsite is light in weight and uniform in size and density, which naturally reduces the pressure on the floor. According to the shape of ceramsite, it does not harm the pipeline and waterproof layer. Moreover, the bathroom itself is a relatively humid place, and ceramsite has certain water absorption and hygroscopicity, which can promote the bonding ability between ceramsite and cement mortar.
Disadvantages of backfilling with building waste residue
Price is an eternal topic, and the owner's first consideration in decoration is price. Construction waste residue is the purchased materials, which have been abandoned, reducing the natural cost and avoiding the waste of some materials. However, if ceramsite is used as backfill, it is necessary to buy materials again, and the cost is relatively increased.
Construction waste residue: as the name implies, it is the materials that can no longer be used in decoration construction, such as concrete chips, waste bricks of masonry bricks, cement, sand, glass, etc. The composition of waste residue is chaotic, organic matter is perishable and gas is produced.
Construction waste residue is generally a mixture of different materials, which can not guarantee uniform particle size and density. Moreover, most of the construction dregs are heavy building materials, and its own weight is difficult to guarantee. If they exceed a certain limit, the floor will be overweight. At the same time, there is no guarantee that there are no sharp objects in the waste residue that will damage the pipeline and waterproof layer.
