In civil construction, especially in high-rise buildings, rock wool boards are commonly used as insulation materials. When selecting rock wool boards for such applications, it is essential to consider key performance indicators like compressive strength, tensile strength, and water absorption. The ideal choice would be three-dimensional rock wool boards, which offer superior mechanical properties and low water absorption. However, due to the complex manufacturing process, the cost of three-dimensional rock wool boards is significantly higher, making them less practical for widespread use.
Considering cost-effectiveness, pendulum-type rock wool boards are often the preferred option. They provide a good balance between performance and price, making them suitable for most civil construction projects. To ensure the right selection, it's important to refer to technical specifications that guide the proper evaluation of different types of rock wool boards.
Below is a table summarizing the key technical performance indices for various types of rock wool boards:
**Table 1: Rockwool Board Technical Performance Index**
| **Project** | **Rock Wool (Pendulum)** | **Three-Dimensional Rock Wool** |
|------------------------------------|--------------------------|---------------------------------|
