Final answer:
Type III Concrete, also known as high early strength concrete, gains strength rapidly after it is poured. It is often used in construction projects that require quick setting and early strength development.
Step-by-step explanation:
Type III Concrete, also known as high early strength concrete, is a specialized type of concrete that gains strength rapidly after it is poured. This type of concrete is often used in construction projects that require quick setting and early strength development, such as high-rise buildings or heavy traffic areas.
The high early strength is achieved through the use of special cementitious materials or chemical admixtures. Type III Concrete is designed to achieve a specified compressive strength within a short period of time, typically 7 to 28 days.
