Study on Hybrid Fiber Reinforced Lightweight Aggregate Concrete

Abstract:

For lightweight aggregate concrete, fiber materials can reinforce its toughness and strength better and improve its segregation degree greatly. Specifically, as the experiment indicates, the fluidity of concrete mix decreases slightly after 0.5% basalt fiber and 0.5% PVA fiber are incorporated into the concrete with FA ceramsite as lightweight aggregate. However, its segregation degree reduces about 50%. And its 28d cubic compressive strength increases 0.7% and 28d splitting tensile strength increases 12.7%. Therefore, this effect is better than that of adding only one kind of fiber.
