What is the primary role of coarse aggregate in concrete?

Step 1: Understand what coarse aggregate is. Coarse aggregate consists of larger particles, like gravel or crushed stone, used in concrete.
Step 2: Recognize that coarse aggregate is mixed with cement, water, and fine aggregate (like sand) to make concrete.
Step 3: Know that the primary role of coarse aggregate is to provide volume to the concrete mix, which helps fill space.
Step 4: Realize that coarse aggregate also adds stability to the concrete, making it less likely to crack or break.
Step 5: Conclude that by providing volume and stability, coarse aggregate contributes to the overall strength of the concrete.
