Kev tshawb fawb txog cov khoom cuam tshuam ntawm basalt fiber concrete
Cov qauv pob zeb ua vaj tse yuav ntsib kev cuam tshuam tsis tau thaum lub sijhawm siv, uas yuav ua rau muaj kev puas tsuaj rau lub qauv, lossis cov teeb meem loj xws li kev puas tsuaj ntawm lub qauv, ua rau muaj kev poob tsis tuaj yeem kho tau. Yuav kom ntseeg tau tias muaj kev nyab xeeb ntawm cov pob zeb ua vaj tse hauv qhov xwm txheej cuam tshuam, nws yog ib qho tseem ceeb uas yuav tsum kawm txog cov yam ntxwv cuam tshuam ntawm cov pob zeb ua vaj tse. Cov yam ntxwv cuam tshuam ntawm Basalt Fiber Cov pob zeb tau raug kawm los ntawm kev xeem SHPB lossis kev xeem poob rauj.
Los ntawm kev sim cuam tshuam pom tias kev sib xyaw ntawm cov fibers basalt tuaj yeem txhim kho qhov cuam tshuam toughness ntawm cov pob zeb, cuam tshuam toughness nrog rau kev nce ntxiv ntawm qhov ntau ntawm cov fiber basalt qhia txog qhov sib txawv ntawm kev nce thiab tom qab ntawd txo qis, kev tshawb fawb cuam tshuam qhia tau hais tias qhov ntim ntawm basalt fiber sib xyaw 0.3% thiab 0.36% ntawm basalt fiber pob zeb cuam tshuam kev ua tau zoo tshaj plaws; piv rau cov yam ntxwv puas tsuaj ntawm cov qauv, kev txhim kho ntawm cov kab nrib pleb thiab qhov kev puas tsuaj zaum kawg rau daim ntawv ntawm kev tawg, pom tias basalt fiber pob zeb rau kev puas tsuaj yas, piv txwv li, kev sib xyaw ntawm basalt fiber tuaj yeem ua rau cov pob zeb nqus tau lub zog cuam tshuam thiab muaj cov nyhuv tawv rau cov pob zeb. Kev sib piv ntawm cov yam ntxwv puas tsuaj ntawm cov khoom xeem, kev txhim kho kab nrib pleb thiab daim ntawv kawg ntawm kev puas tsuaj tawg, pom tias basalt fiber pob zeb rau kev puas tsuaj yas, uas yog, sib xyaw nrog cov fiber basalt tuaj yeem ua rau cov pob zeb ua vaj tse nqus tau lub zog cuam tshuam zoo, thiab muaj cov nyhuv tawv rau cov pob zeb ua vaj tse. Cov kws tshawb fawb tau kawm txog kev tiv thaiv kev cuam tshuam ntawm cov pob zeb basalt fiber nrog rau qhov ntim ntawm basalt fiber (0%, 0.4%, 0.6%, 0.8%) thiab qhov ntev ntawm basalt fiber (6mm thiab 18mm) ua cov hloov pauv. Nws tau pom tias basalt fibers tuaj yeem txhim kho qhov cuam tshuam toughness ntawm cov pob zeb ua vaj tse, thiab qhov cuam tshuam toughness nrog kev nce ntawm kev sib xyaw fiber thiab ua loj dua; tib yam kev sib xyaw fiber, qhov ntev ntawm fiber ntawm 6mm kev ua tau zoo dua li qhov ntev ntawm 18mm fiber pob zeb ua vaj tse.
Hauv kev xaus, basalt fiber Cov tshuaj admixture tuaj yeem txhim kho qhov kev ua tau zoo ntawm cov pob zeb ua vaj tse, tab sis cov tshuaj fiber zoo tshaj plaws tsis sib xws, los ntawm kev sib piv kev tshuaj xyuas pom tias qhov xwm txheej no yog tshwm sim los ntawm txoj kev sim, qhov sib piv ntawm cov pob zeb sib xyaw, basalt fiber kev sib xyaw thiab lwm yam, kev sib koom ua ke ntawm cov yam tseem ceeb yuav tsum tau txhawb nqa hauv kev sim yav tom ntej. Tsis tas li ntawd, kev tshawb fawb uas twb muaj lawm tsom mus rau qhov cuam tshuam ntawm cov tshuaj fiber rau nws qhov kev ua tau zoo, thiab yuav tsum tau ua tiav yav tom ntej los kawm txog qhov cuam tshuam ntawm kev ntxhov siab thiab lwm yam rau kev ua tau zoo.
