Lime-soil is a traditional building material in northern China, made by mixing clay, lime , and water. Many people frequently use 37 lime-soil mixtures, so how do you calculate the amount of lime needed for 37 lime-soil? Let's find out below.
How do you calculate the amount of quicklime needed for 37 lime-soil mixture?
37 lime-soil refers to the volume ratio of quicklime to clay. Quicklime is also known as lime powder. The volume ratio of quicklime to clay is generally 3:7. This lime-soil is called " 3:7 lime-soil". Each cubic meter of 3:7 lime-soil generally contains 0.3 cubic meters of quicklime and 0.7 cubic meters of clay.
The role of lime soil
1. Sterilization and insecticidal
Quicklime has sterilization and insecticidal properties. Spreading an appropriate amount of undigested quicklime on the soil will cause it to react with moisture in the soil, releasing a large amount of heat, which can kill pathogens and pests in the soil.
2. Adjusting soil properties
Quicklime reacts with water to produce calcium hydroxide, an alkaline substance. If quicklime is applied to acidic or slightly acidic soil, it can effectively neutralize the acidity, change the soil properties, and alleviate problems such as soil compaction.
3. As a desiccant
Quicklime can be used as a desiccant, and it has a very good dehumidifying effect.
4. Supplement calcium to water bodies
When quicklime comes into contact with water, it undergoes a chemical reaction to form calcium carbonate. This process releases a large amount of free calcium into the water, which can increase the calcium content of the water and help fish, shrimp and other organisms absorb calcium for growth.
5. Increase the pH value of the water.
When the water is acidic and the pH value is low, it will affect the normal growth of fish and shrimp. Therefore, quicklime can be added to neutralize the acidic water and increase the pH value of the water.
