Study on the Influence of Fibers to the Physical Mechanical Properties of Foam Concrete

Foam concrete has been widely used in building, infrastructure and fire prevention fields because of its lightweight, excellent heat and sound insulation performance. However, due to its high porosity, the compressive strength of foam concrete is usually low, which limits its application in some high-strength structures. In order to solve this problem, researchers improve the mechanical properties of foam concrete by adding different types of fiber materials. This paper summarizes the research progress of fiber on the performance of foam concrete, and analyzes the influence of different types of fiber (such as polypropylene fiber, basalt fiber, polyvinyl alcohol fiber, etc.) on the performance of foam concrete. The research shows that adding proper amount of fiber into foam concrete can effectively improve the mechanical, durability, dry shrinkage and other properties of foam concrete.
