How to eliminate the problems of artificial sand and improve the quality of mechanism sand

Artificial sand, also known as manufactured sand or crusher sand, is increasingly being used as a substitute for natural sand in concrete production. However, some challenges associated with artificial sand, such as reduced strength, increased shrinkage, and poor workability, have led to concerns about its quality. To improve the quality of mechanism sand and eliminate the problems associated with artificial sand, consider the following steps:

1. Select the right crusher: The quality of the final product depends significantly on the type of crusher used. Choose a crusher that produces well-graded and angular particles, which contribute to better strength and workability.

2. Control the particle size distribution: Ensure that the produced sand has a consistent particle size distribution by using appropriate screening and classification equipment. A uniform particle size distribution improves the workability and strength of the concrete.

3. Minimize dust and fines: Control the production of dust and fines during the crushing process to avoid negative effects on concrete properties, such as increased shrinkage and reduced strength.

4. Use admixtures: Incorporate admixtures, such as superplasticizers, accelerators, and retarders, to improve the workability and strength of the concrete made with artificial sand.

5. Proper curing and moisture control: Ensure that the concrete made with artificial sand is properly cured and kept at optimal moisture levels to achieve the desired strength and durability.

6. Quality control and testing: Implement a robust quality control program that includes regular testing of the produced sand and concrete made with it. This will help identify and address any issues before they become problematic.

7. Education and training: Educate and train the workforce involved in the production and use of artificial sand to ensure proper handling and application.

By following these steps, you can improve the quality of mechanism sand and eliminate the problems associated with artificial sand. However, it is crucial to conduct regular quality checks and make necessary adjustments to maintain the desired product quality.
