Talosaga
➢ Lelei fetuutuunai i ituaiga uma o sima, faʻaleleia le faʻaogaina o sima, faʻaaogaina lautele i auala, nofoaafi, Alalaupapa, tunnels, eletise, DAMS, fale maualuluga ma isi galuega.
1. Fa'afefiloi fuala'au ile 0.5%-1.0%,0.75% fa'afefiloi fuala'au fautuaina.
2. Saunia fofo pe a manaomia.
3. Fa'aaoga sa'o o le sui o le pa'u ua fa'atagaina, i le isi itu o le fa'aopoopoga o le so'o e soso'o ma le fa'asusu vai(vai-sima fua:60%).
Fa'atinoga Autu
➢ E mafai e le SNF-A ona tu'uina atu le paluga vave fa'apipi'i saosaoa, maualuga le liquifying a'afiaga, maualalo le ea entraining aafiaga.
➢ O le SNF-A e fetaui lelei ma ituaiga sima po'o gypsum binders, isi mea fa'aopoopo e pei o le fa'afu'afu, mafiafia, fa'aluma, mea fa'alautele, fa'avave ma isi.
➢ SNF-A e fetaui lelei mo le pa'u ta'ele, fa'ameamea fa'alelei, sima foliga fa'alelei fa'apea fo'i fa'ama'a fola lanu.
Galuega Fa'atino
➢ E mafai ona fa'aogaina le SNF e fai ma susū mo le paluga fa'afefiloi mago ina ia maua ai le fa'aogaina lelei.
☑ Teuina ma le tuʻuina atu
E tatau ona teuina ma tuʻuina atu i lalo o tulaga mamago ma mama i lona uluai afifi ma alu ese mai le vevela. A maeʻa ona tatalaina le afifi mo le gaosiga, e tatau ona toe faʻamaufaʻailogaina faʻamau ina ia aloese mai le faʻaogaina o le susu.
☑ Ola fa'asa
Ole ola ole 10 masina. Faʻaaoga i le vave e mafai ai i lalo o le maualuga o le vevela ma le susu, ina ia aua neʻi faʻateleina le avanoa o le keke.
☑ Saogalemu o oloa
Naphthalene based superplasticizer SNF-A e le o se mea mata'utia. O isi fa'amatalaga e uiga i itu saogalemu o lo'o tu'uina atu i le Pepa o Fa'amatalaga Saogalemu Mea.
