Which mechanism sand is better?

It is difficult to determine which mechanism sand is better without knowing the specific application or requirements. Mechanism sand, also known as quarry dust or crushed stone, is often used in construction and landscaping projects for various purposes, such as leveling, filling, and mixing with concrete or mortar. The best type of mechanism sand depends on the project's needs and the desired outcome.

Some factors to consider when choosing the best mechanism sand include:

1. Grain size: Coarser sand is generally used for filling and leveling, while finer sand is better for mixes that require a smooth finish.

2. Shape and texture: The shape and texture of the sand particles can affect the overall quality of the finished product. For example, rounded particles may provide a more aesthetically pleasing appearance, while angular particles may be better for providing better bonding with other materials.

3. Quality and purity: The quality and purity of the sand can also play a significant role in the performance of the final product. Low-quality sand may contain impurities or contaminants that can negatively affect the strength and durability of the concrete or mortar.

4. Cost: The cost of mechanism sand can vary depending on the type, grade, and supplier. It is essential to weigh the benefits and drawbacks of each option and select the most cost-effective choice that meets the project's requirements.

It is recommended to consult with a construction professional or a supplier of building materials to determine which type of mechanism sand is best suited for a specific project.
