Hauv kev tsim kho niaj hnub no, qhov teeb meem tawg ntawm mortar yeej ib txwm yog qhov tseem ceeb cuam tshuam rau qhov project zoo thiab kav ntev. Nyob rau hauv xyoo tas los no, basalt tws filaments, raws li cov khoom siv tshiab, tau pom zoo los tiv thaiv kev tawg hauv kev hloov kho mortar, muab cov kev daws teeb meem tshiab rau kev tsim kho.

Khoom siv

Basalt chopped hlau yog ibfiber ntauua los ntawm fusing natural basalt ore thiab tom qab ntawd kos duab thiab txiav nws, uas muaj peb qhov zoo:

1. Lub zog muaj zog: tensile lub zog ntawm 3000 MPa lossis ntau dua, 3-5 npaug ntau dua li cov tsoos PP fiber ntau

2. Zoo heev alkali tsis kam: tseem nyob ruaj khov nyob rau hauv alkaline ib puag ncig nrog pH qhov tseem ceeb mus txog 13.

3. Peb-dimensional thiab chaotic tis: luv txiav filaments ntawm 3-12mm nyob rau hauv ntev tuaj yeem tsim peb-dimensional reinforcing network hauv mortar.

Anti-cracking mechanism

Thaum lub mortar tsim shrinkage kev nyuaj siab, cov uniformly faib basalt fibers zoo tiv thaiv qhov nthuav ntawm micro-cracks los ntawm "bridging effect". Kev sim qhia tau hais tias qhov sib ntxiv ntawm 0.1-0.3% ntim tus nqi ntawm basalt luv txiav hlau tuaj yeem ua mortar:

- Thaum ntxov yas shrinkage tawg txo los ntawm 60-80

- Qhuav shrinkage yog txo los ntawm 30-50

- Txhim kho qhov cuam tshuam los ntawm 2-3 zaug

Engineering Advantages

Piv rau cov khoom siv fiber ntau,basalt fiber ntau tws strandshauv mortar show:

- Zoo dua dispersibility: zoo heev compatibility nrog cementitious cov ntaub ntawv, tsis muaj agglomeration.

- Kev ua haujlwm zoo: tsis muaj xeb, tsis muaj kev laus, kev pab cuam lub neej ntau dua 50 xyoo.

- Kev tsim kho yooj yim: tuaj yeem sib xyaw ncaj qha nrog cov khoom siv khib nyiab qhuav yam tsis muaj kev cuam tshuam rau kev ua haujlwm.

Tam sim no, cov thev naus laus zis no tau ua tiav rau kev kub ceev railway ballastless khiav phaj, underground pipeline corridor, lub tsev sab nrauv phab ntsa plastering thiab lwm yam dej num, thiab qhov kev ntsuam xyuas tiag tiag qhia tau hais tias nws tuaj yeem txo qhov tshwm sim ntawm cov kab nrib pleb los ntawm ntau dua 70%. Nrog rau txoj kev loj hlob ntawm lub tsev ntsuab, cov khoom siv txhawb nqa zoo li no nrog cov khoom siv ntuj tsim thiab kev ua tau zoo heev yuav tau siv ntau dua.
