Kev tsim kho txoj kev thiab kev ceev faj rau Chopped Basalt Fiber Concrete

1. Kev tsim kho Kub

Txiav basalt fiber ntau pob zeb Nws yuav tsum tau ua tib zoo tsim nyob rau hauv qhov kub ntawm -5 ° C mus rau 25 ° C. Ob qho tib si siab dhau los yog qis qis tuaj yeem ua rau muaj kev sib txuam tsis sib xws.

2. Kev Tswj Xyuas Kev Ua Haujlwm Zoo

Kev tswj kom zoo rau chopped Basalt Fiber ntau kev tsim kho vaj tse yuav tsum tsom rau kev tshuaj xyuas cov khoom siv raw, ntsuas qhov tseeb, thiab qhov zoo ntawm cov txheej txheem sib xyaw.

2.1 Mix Design

Nyob rau hauv kev tsim kho, qhov kev faib ua feem ntawm tws basalt fiber yuav tsum tau xaiv nyob rau hauv ib tug tsim nyog ntau yam raws li qhov project yuav tsum tau. Txij li thaum tws basalt fiber nws tus kheej tsis chemically hnov ​​​​mob nrog rau lwm yam khoom vaj khoom tsev los yog admixtures, nws cov inclusion feem ntau tsis hloov tus thawj qhob mix tsim qauv. Thaum lub sij hawm tsim kho, qhov zoo ntawm tag nrho cov ntaub ntawv yuav tsum tau nruj me ntsis txiav txim raws li kev tsim mix ratio thiab ib batch mixing kom muaj nuj nqis.

Table 1: Piv txwv ntawm Kev Sib Tw Zoo Tshaj Plaws rau Basalt Fiber Reinforced Concrete

Kev ntsuam xyuas tau pom tias cov ntsiab lus fiber ntau dua tsis tas yuav ua rau muaj kev sib tsoo zoo dua. Thaum cov ntsiab lus fiber ntau tsis tshaj 1.2 kg / m³, lub zog compressive ntawm cov pob zeb qhia tau hais tias qhov pib nce ntxiv tom qab qhov txo qis thaum cov ntsiab lus fiber ntau nce (muaj tus nqi siab tshaj).

2.2 Kev pub noj ib ntus thiab txoj kev

Thaum lub sij hawm sib tov, chopped basalt fibers yuav tsum zoo dua ntxiv ib txhij nrog aggregates xws li xuab zeb thiab gravel. Nws raug nquahu kom sib npaug ntawm cov fibers rau hauv qhov sib tov thaum pub mis rau hauv cov xuab zeb thiab gravel, ces ntxiv dej rau ntub sib xyaw.

Fiber ntxiv txoj kev tuaj yeem muab faib ua phau ntawv pub mis thiab pub mis tsis siv neeg:

Phau ntawv pub mis: Tom qab cov kub aggregate yog pub rau hauv lub tov khoom, lub hnyav basalt fibers yog manually ntxiv. Txoj kev no yog kev siv zog ntau, thiab kev sib xyaw ua ke yog qhov qis dua. Lub sijhawm sib tov yuav tsum tau txuas ntxiv kom tsim nyog kom ntseeg tau tias muaj fiber ntau dispersion.

Tsis siv neeg pub mis:Lub basalt fiber feeder yog siv rau kev ntsuas tsis siv neeg thiab ib txhij pub rau hauv lub tov khoom nrog cov kub sib xyaw. Fiber feeders feem ntau yog nruab nrog tsis siv neeg metering, pre-dispersion, thiab pneumatic conveying mechanisms, muab qhov zoo ntawm qhov yooj yim, ceev, thiab raug ntxiv. Txoj kev tsim nyog yuav tsum raug xaiv raws li cov xwm txheej ntawm qhov chaw tsim kho tiag tiag.

2.3 Slump Adjustment

Qhov sib ntxiv ntawm fibers yuav ua rau me ntsis viscosity ntawm cov pob zeb sib tov, cuam tshuam nws cov slump. Yog tias qhov poob qis tsis ua raws li kev tsim kho, cov khoom siv yas lossis cov dej txo qis yuav tsum tau ua ntej rau kev hloov kho, thiab qhov teeb meem yuav tsum tsis txhob daws los ntawm kev nce cov dej.

2.4 Kev tsim thiab kho

Kev sib xyaw ua ke ntawm cov ntoo basalt fibers tsis muaj qhov tshwj xeeb rau kev tsim, tab sis nws yuav tsum tau ua kom ntseeg tau tias nws yog siab vibrated thiab compacted. Nws cov kev cai curing yog tib yam li cov pob zeb zoo tib yam.
