Study on Polypropylene Twisted Bundle Fiber Reinforced Lightweight Foamed Concrete

Recent industrial developments have focused more and more on the applications of lightweight foamed concrete (LFC) in the construction industry, having advantages over normalstrength concrete. LFC, however, has several drawbacks including brittleness, high porosity, excessive drying shrinkage, rapid...

Practical engineering typically chooses steel fiber or polymer fiber to increase the tensile and fracture resistance of LFC.

The mechanical and durability properties of PTBF-reinforced LFC were determined through compression, flexural, splitting tensile, flow table, porosity, and water absorption tests. The results show that the addition of PTBF in LFC significantly improves the strength properties (compressive, flexural, and splitting tensile strengths) and reduces the water absorption capacity and porosity. The optimal weight fraction of PTBF was between 1.5 and 2.0% for mechanical properties enhancement. The inclusion of PTBF increased the ductility of LFC, and the specimens remain intact from loading to failure.
