Chemical and Mechanical Residences of PVA Fiber
PVA fiber is a synthetic polymer characterized by high hydrophilicity, moderate modulus of elasticity, and strong interfacial bonding with cementitious materials. Unlike steel fibers, which are prone to deterioration, or polypropylene fibers, which offer minimal mechanical support, PVA fibers integrate adaptability with toughness– displaying tensile strengths exceeding 1,600 MPa and prolongation at break around 6– 8%. Their microstructure enables efficient crack linking, power dissipation, and post-cracking ductility, making them perfect for applications needing strength and influence resistance without compromising workability.
System of Fracture Control and Ductility Enhancement
The key feature of PVA fiber in concrete is to manage microcrack breeding and enhance post-cracking actions. Ni sa veisoliyaki vakatautauvata ena loma ni matrix ., PVA fibers cakacaka me vaka na veika lalai-vakadeitaki ka semati ira na ramusu tekivu ena gauna ni vakavodoki se vakalailaitaki. Na iwalewale oqo e vakalevutaka vakalevu na kaukauwa ni flexural, kaukauwa ni ramusu, kei na rawa ni vakayagataki ni kaukauwa .. Ena idinia ni simede ni veivakatorocaketaki (ECC), Na fibers ni PVA e vakatara na itovo ni veivakasaurarataki, na vanua e vakaraitaka kina na ka e buli e vuqa na fractures vinaka ka sega ni veivakarusai ni sega ni rawata ..
