Generally speaking, the dry mortar mix ratio needs to be adjusted according to the specific use, and different materials and proportions are required for different environments.
Here I will list the standard dry mortar mix ratios for your reference.
Masonry mortar ratio
Masonry mortar is commonly used for brickwork, blockwork, and stone masonry. The ratio of masonry mortar typically consists of the following ingredients:
– Portland cement
– Hydrated lime
The most common ratio for masonry mortar is 1:1:6, which means one part Portland cement, one part hydrated lime, and six parts sand. However, the ratio can vary depending on the specific project requirements and the type of materials being used. Other common ratios include:
– 1:2:9 (one part cement, two parts lime, nine parts sand)
– 1:3:12 (one part cement, three parts lime, 12 parts sand)
Plastering mortar ratio
The plastering-mortar mix ratio refers to the proportion of different materials (such as cement, sand, and water) used to make the plastering mixture for application on walls or ceilings. The exact ratio can vary depending on factors like the plastering type and the surface conditions to be plastered. Typically, the percentage for plastering mortar is 1:3 or 1:4, which means one part of cement to three or four pieces of sand. The exact ratio may vary depending on the type of sand, cement, and additives used and the project’s specific requirements.
Flooring mortar mix ratio
The flooring mortar is used for the initial treatment of the ground mortar; the specific ratio needs to be prepared by the ratio of cement, perlite, 107 rubber, sand, and water volume ratio of about 1:2:0.5:2.4, by this standard configuration of the mortar used as ground treatment, the effect is better.
1. Ordinary mortar ratio: cement: sand = 1:3 or 1:4, add the right amount of water as needed.
2. Waterproof mortar ratio: cement: fly ash: sand = 1:0.2:3; add the right amount of water as needed.
3. Polymer mortar ratio: cement: sand = 1:3, add polymer enhancer, and add the right amount of water as needed.
4. Fire-resistant mortar ratio: cement: clay: sand = 1:0.5:4, add the right amount of water as needed.
It should be noted that different sand materials and particle sizes will also impact the dry mortar mix ratio, so it needs to be adjusted according to the specific situation. It is also necessary to pay attention to details during the preparation process, such as adequate mixing, adding each component in proportion, and adjusting the water content of cement.
