Questions & Step-by-Step Solutions
Which aggregate size is generally preferred for high-strength concrete?
Step 1: Understand that high-strength concrete is a type of concrete that has a higher compressive strength than normal concrete.
Step 2: Know that aggregates are materials like sand (fine aggregate) and gravel or crushed stone (coarse aggregate) that are mixed with cement to make concrete.
Step 3: Realize that using a mix of both fine and coarse aggregates helps fill the spaces between the larger particles, which improves the overall density of the concrete.
Step 4: A denser mix means that the concrete can withstand more pressure and is stronger, which is why a combination of different sizes of aggregates is preferred for high-strength concrete.
