cement mortar tiling is a traditional method and is also the most widely used and commonly used method in China. Because the decorative materials in the past were mainly glazed tiles , which had a higher water absorption rate, most families used traditional materials such as cement mortar.
Cement mortar is a pure physical tiling. It relies on mechanical anchoring of physical properties to paste ceramic tiles. What are the obvious characteristics of cement mortar?
1. Cement mortar has limited adhesion
As the tiles size increases and the water absorption decreases, the mechanical bite force after the cement mortar is dry and it is difficult to "bite" the back of the tiles. A slightly larger tiles or tiles with low water absorption are required to support the wall, otherwise bricks will fall and slip. This is all due to insufficient cement mortar bonding.
2. Cement needs to be stirred on site, and the quality is not guaranteed.) Due to environmental protection, the national construction standard does not allow the stirring of cement river sand, concrete, etc. on site. Large-scale projects have begun to be implemented, while small projects and home decoration are still allowed at present, but the on-site mixing is dusty and the construction environment is harsh, which is very different from the current decoration trend.
2) Cement mortar tiling, hollowing is a common phenomenon. In addition, once water is exposed to, cement will undergo hydration (the hydration of cement will continue to occur within 20 years), which means continuous shrinkage and solidification, which will lead to hollowing and cracking in the beginning.
Why is cement mortar tiling gradually not advocated now? The current tiles have high density, and the porosity of is also low, which increases the difficulty of tiling. When the tiles are larger and the density is higher, it is difficult for cement mortar to stick firmly and stably with physical properties. There are often problems such as hollowing and falling off in tiles. In addition to the progress of laying materials, more and more people choose more efficient laying methods.
