Kev Piav Qhia Luv:
Cov lus piav qhia txog cov khoom los ntawm tus neeg muag khoom
Txheej txheem cej luam
Lub tuam txhab siv cov thev naus laus zis tshiab ntawm cov khoom siv cement-based uas muaj kev ua tau zoo heev raws li cov ntaub ntawv CM cementitious los tsim cov khoom ASCEND WHITE Cement UHPC. Cov khoom muaj cov yam ntxwv xws li tsis tshua muaj zog, muaj zog heev, nws tus kheej leveling, du, mos thiab puag ncig. Nws yog qhov tsim nyog rau kev kho cov khoom lag luam tus kheej. Nws siv cov khoom siv dawb ua cov khoom siv hauv paus thiab ntxiv cov xim thiab cov fibers kom ua tiav cov qauv ntawm cov ntaub thaiv phab ntsa nrog cov qauv nyuaj thiab cov qhov loj.
Cov pab pawg kws tshaj lij ntawm cov khoom no yog tsim los ntawm cov kws tshaj lij los ntawm Tsev Kawm Ntawv ntawm Civil Engineering thiab Tsev Kawm Ntawv ntawm Cov Khoom Siv ntawm Tongji University, thiab tau koom ua ke nrog cov pab pawg saum toj kawg nkaus hauv kev lag luam hauv Singapore. Nws muaj kev paub txog kev tsim kho vaj tse nplua nuj ntsig txog kev sib koom ua ke ntawm cov ntaub ntawv cement thiab cov qauv kho kom zoo nkauj, thiab tuaj yeem muab cov kev pabcuam sib koom ua ke tag nrho.

Kev ua tau zoo ntawm cov khoom
Muaj zog heev
Thaum ntxiv 2% ntawm cov polymer fiber rau cov khoom, lub zog 28 hnub yog ntau dua 120MPa.
kev ntsuas tus kheej
Cov khoom muaj kev ua haujlwm zoo thiab qib nthuav dav yog ntau dua 300 hli hauv lub xeev tsis muaj fiber, ua rau nws haum rau cov khoom lag luam tus kheej.
qis shrinkage
Tus nqi shrinkage ntawm cov khoom yog qis, thiab qhov shrinkage deformation los ntawm 3 hnub mus rau 28 hnub yog tsis pub ntau tshaj 300 micro-strain.
