Which property of aggregates is crucial for ensuring good concrete performance?
Correct Answer: Shape and texture of aggregates
Step 1: Understand what aggregates are. Aggregates are materials like sand, gravel, or crushed stone used in concrete.
Step 2: Learn about the shape of aggregates. The shape can be round, angular, or flat, and it affects how well they fit together.
Step 3: Know about the texture of aggregates. The texture can be smooth or rough, which influences how well they bond with cement.
Step 4: Realize that good bonding between aggregates and cement is important for strong concrete.
Step 5: Understand that workability refers to how easy it is to mix and pour concrete. The shape and texture of aggregates can make concrete easier or harder to work with.
Step 6: Conclude that both the shape and texture of aggregates are crucial for ensuring good concrete performance.
