Which type of aggregate is preferred for high-performance concrete?

Step 1: Understand what high-performance concrete is. It is a type of concrete that has superior strength, durability, and workability.
Step 2: Learn about aggregates. Aggregates are materials like sand, gravel, or crushed stone that are mixed with cement to make concrete.
Step 3: Identify the types of aggregates. There are two main types: natural aggregates (like sand and gravel from nature) and artificial aggregates (man-made materials).
Step 4: Know the importance of aggregate quality. High-performance concrete needs aggregates that are strong, clean, and have consistent properties.
Step 5: Recognize that natural aggregates are usually preferred. They are often more reliable in quality and performance compared to artificial aggregates.
Step 6: Conclude that for high-performance concrete, using natural aggregates is the best choice.
