Final answer:
Concrete mixture typically consists of 10-15% cement, 60-75% aggregate, and 15-20% water by volume. Proportions may vary for specialized applications like lightweight concrete, which uses different types of aggregates for benefits such as reduced load and better thermal insulation.
Step-by-step explanation:
Typically, a concrete mixture is comprised of various proportions of cement, aggregate, and water. These components are crucial for the formation of concrete, which is a composite material utilized extensively in construction. The exact percentages can vary depending on the specific application and desired properties of the concrete, but a common mix by volume could consist of about 10-15% cement, 60-75% aggregate, and 15-20% water.
Lightweight concrete is a specific type of concrete that uses lightweight coarse aggregate like shale, clay, or slate. This kind of concrete offers benefits such as reduced structural load, faster building rates, and excellent thermal protection. The mention of lightweight concrete highlights that the component percentages can differ when specialized aggregates or applications are involved.
