What is the difference between cement mortar and dry mix mortar?
Cement mortar is a mixture of cement, cát, and the appropriate water for on-site construction.
Dry mortar is a mixture of cement, cát, chemical additives, vân vân., mixed in specific proportions, then mechanically mixed and packaged and sealed, and then mixed with the right amount of water when used. Dry-mixed mortars are usually of more consistent quality and more efficient, as they avoid errors and waste in the field mixing process.
Cement mortar and dry-mixed mortar are two common materials used in construction, and they differ in the following ways:
1. Material composition: Cement mortar mainly consists of cement, lime, and sand, while dry-mixed mortar adds various additives, such as expansion agents, polymers, vân vân., to improve its performance and efficiency.
2. Usage: Cement mortar needs to be blended with water to become mortar before it is used, while dry-mixed mortar is directly mixed with water for construction, which is convenient and fast.
3. Characteristics: The strength of cement mortar is higher than that of dry-mixed mortar, but the adhesion and adaptability are poor, and cracking is easy to occur; dry-mixed mortar is adjusted according to the required ratio to achieve the required characteristics.
4. Construction environment: Cement mortar needs to pay attention to environmental factors such as temperature and humidity during construction, otherwise it may have poor curing and other problems; dry-mixed mortar is more suitable for construction in some unique environments because it contains chemical additives that can improve its water resistance, crack resistance, and other properties.
5. Service life: Compared with cement mortar, dry-mixed mortar pays more attention to the uniformity and stability of the material and has higher mechanical strength and service life.
In a word, cement and dry mix mortar have their characteristics and applicability and will select according to specific needs before construction.
