What are the advantages of manufactured sand compared to natural sand?

• Strength: While the strength of manufactured sand is slightly lower than that of river sand, it still meets the GB/T14168-4293 standard and is suitable for ordinary concrete. Controlling the cement-to-sand ratio, the sand’s crushing index, and the stone powder content ensures its proper application.
• Particle Shape Quality: The particles of manufactured sand are irregular and curved, providing better adhesion and higher compressive strength, leading to longer service life.
• Compatibility with Other Raw Materials (e.g., Concrete): There is no significant difference between manufactured sand and natural sand when mixed with concrete and other materials. Tests show that manufactured sand may require slightly more water.

What are the advantages of sand produced by a sand making machine?

• Composition: The raw materials for manufactured sand are selected manually, ensuring uniform texture and pure composition, with consistent mineral and chemical components.
• Fineness Modulus: The fineness modulus of manufactured sand can be controlled manually, unlike natural sand, which has a fixed modulus.
• Adhesion and Compressive Strength: Due to their curved particle shapes, manufactured sand particles have higher adhesion and compressive strength.
• Stone Powder Content: Although the stone powder content in manufactured sand can be relatively high (generally not exceeding 20%), it does not negatively affect the setting time or strength of concrete.
