Polypropylene fiber (PPF) yog ib hom khoom siv polymer uas muaj qhov hnyav sib dua, muaj zog heev, thiab tiv taus corrosion. Qhov tsis kam ntawm cov pob zeb ua vaj tse tuaj yeem txhim kho los ntawm kev ntxiv cov polypropylene fibers. PPF tuaj yeem ua kom zoo dua qhov pore loj ntawm cov pob zeb ua vaj tse. Yog li ntawd, qhov ruaj khov ntawm cov pob zeb ua vaj tse tau txhim kho ntau vim tias PPF tuaj yeem thaiv kev nkag mus ntawm dej lossis cov ions tsis zoo hauv cov pob zeb ua vaj tse. Cov ntsiab lus fiber sib txawv, txoj kab uas hla fiber, thiab qhov sib xyaw ua ke ntawm cov fiber yuav muaj cov teebmeem sib txawv ntawm cov ntsuas ruaj khov. Qhov ruaj khov ntawm cov pob zeb ua vaj tse tuaj yeem txhim kho ntxiv los ntawm kev sib xyaw ua ke PPFs thiab cov hlau fibers. Qhov tsis zoo ntawm PPF hauv kev siv hauv cov pob zeb ua vaj tse yog qhov tsis zoo hauv cov pob zeb ua vaj tse thiab kev sib txuas tsis muaj zog nrog cov cement matrix. Cov txheej txheem los kov yeej cov kev tsis zoo no yog siv cov fiber hloov kho nrog nanoactive hmoov lossis kev kho tshuaj.

Cov fiber tiv thaiv kev tawg yog cov fiber ntau monofilament organic uas muaj zog heev uas siv cov fiber-grade polypropylene ua cov khoom siv raw thiab ua tiav los ntawm cov txheej txheem tshwj xeeb. Nws muaj cov tshuaj tiv thaiv acid muaj zog, alkali muaj zog, thermal conductivity tsis muaj zog, thiab cov khoom siv tshuaj ruaj khov heev. Kev ntxiv mortar lossis concrete tuaj yeem tswj tau cov kab nrib pleb me me los ntawm kev hloov pauv kub hauv theem pib ntawm cov yas shrinkage ntawm mortar thiab concrete, tiv thaiv thiab tiv thaiv kev tsim thiab kev loj hlob ntawm cov kab nrib pleb, thiab txhim kho qhov kev tiv thaiv kab nrib pleb, kev tsis nkag, kev cuam tshuam thiab kev tiv thaiv av qeeg. Nws tuaj yeem siv dav hauv kev tsim kho dej hauv av, ru tsev, phab ntsa, pem teb, pas dej ua ke, qab nthab, txoj kev thiab choj hauv kev lag luam thiab pej xeem kev tsim kho. Nws yog cov khoom siv tshiab zoo tagnrho rau kev tsim kho mortar thiab concrete nrog kev tiv thaiv kev tawg, tiv thaiv kev nqus thiab kev puas tsuaj.
