1. The compressive strength of the mortar. Mortar needs to have a certain compressive strength to meet the structural requirements of the building. Different projects have different requirements for the strength of the mortar, therefore, when preparing the mortar, it is necessary to choose the appropriate material and ratio to ensure that the strength of the mortar meets the specified standards.
2. Water retention of mortar. Water retention refers to the ability of a mortar to retain moisture during storage, transportation, and use. Good water retention can prevent the mortar from drying and cracking prematurely, so as to ensure its construction performance and service life.
3. The adhesion of the mortar. Mortar needs to have good adhesion in order to bond firmly with the building material. This requires the mortar to have sufficient bond strength and adhesion to ensure a reliable bond in all parts of the building.
4. Durability of mortar. Durability refers to the stability and anti-aging performance of the mortar during use. Buildings will be affected by the natural environment, chemical corrosion and other factors during use, therefore, mortars are required to have good durability to ensure the long-term safe use of buildings.
5. Construction manufacturability. Mortar needs to have good construction technology, including good workability, fluidity, etc., so that various construction operations can be completed easily and quickly in the construction process.
