Impembelelo ye-Basalt Fiber kwi-Permeable Concrete
I-basalt fiber, njengenoveli ye-inorganic, ukusebenza okuphezulu, kunye ne-eco-friendly material, iphakamisa kakhulu iimpawu zoomatshini, ukuqina, kunye nokusebenza kwekhonkrithi evuzayo. Apha ngezantsi lucazululo oluninzi lweempembelelo zalo kunye neeparamitha zokwandisa:
- Impembelelo kwiiPropati zoomatshini
UkuPhuculwa koKunyanzeliswa kunye neFlexural Amandla
I-basalt fiber ukuqinisa ngokufanelekileyo kwandisa amandla oxinzelelo kunye nokuguquguquka kwekhonkrithi evuzayo. Uphononongo lubonisa ukuba iintsinga zenza ubume bothungelwano olunamacala amathathu, okomeleza iqhina phakathi kweeaggregates kunye nesamente intlama lo gama kuthintela ukwanda kokuqhekeka. Umzekelo:
Amandla oxinzelelo: Nge-12 mm kunye ne-24 mm fibers, amandla oxinzelelo aqala ukwanda aze anciphise kunye nomxholo ophezulu wefiber. I-dosage efanelekileyo yi-0.1% -0.15% (ngomthamo), kunye ne-24 mm fibers ifezekisa amandla oxinzelelo oluphezulu lwe-24.3 MPa (kwi-0.1% dosage).
Amandla e-Flexural: Ubude beFiber bunempembelelo ecacileyo ngakumbi kumandla aguquguqukayo. Ngokomzekelo, ii-fibers ze-18 mm zonyusa amandla e-flexural nge-66.44% xa kuthelekiswa nekhonkrithi ecacileyo ngenxa yokubambisana okuphuculweyo kwe-interface ukusuka ekudibaneni kwe-fiber-aggregate.
Ukuqina okuphuculweyo kunye nokuDumba
"Isiphumo sokuvala" se IFayibha yeBasalts iphucula ukuqina, ukuguqula iindlela zokungaphumeleli ukusuka kwi-brittle ukuya kwi-ductile. Uhlalutyo lweMicroscopic lubonisa ukuba iifiber zizinzisa ukwakheka kwamathambo ngaphakathi kwe-matrix yesamente, ngokufanelekileyo ithintela ukukhula kokuqhekeka.
Impembelelo kwiPermeability
I-Coefficient yokuNcitshiswa kwePermeability
Ukudityaniswa kweFayibha ngokuyinxenye ibhloka iipores, kwehlisa ukungeneka. Ngokomzekelo, ukunyuka kwe-fiber content ukusuka kwi-0.05% ukuya kwi-0.2% ngokuthe ngcembe kunciphisa i-coefficient yokulinganisa, kodwa isadibana neenkcukacha (umzekelo, ukunyamezela> 1 mm / s kwi-20% porosity).
Ukulinganisa i-Porosity kunye neFiber Parameters
Iintsinga ezinde (umzekelo, 12 mm → 24 mm) zonyusa kancinane i-porosity kodwa zisehlisa ukungeneka.
Ukudibanisa iifibers kunye ne-admixtures mineral (umzekelo, i-fly ash) ilungisa ubume bepore, ukunciphisa ilahleko yokungena ngelixa ugcina amandla.
- Ukuphuculwa kweFrost Resistance
Iifayibha zebasalt ukwandisa imfezeko yolwakhiwo lwangaphakathi, ukonyusa kakhulu ukuxhathisa kweqabaka:
Emva kwemijikelo ye-100 yokunyibilika komkhenkce, iisampulu eziqiniswe ngefayibha zibonisa ilahleko enkulu ephantsi njenge-0.9% kwaye igcina i-62.5% ehambelana nemodyuli eguquguqukayo.
Intsebenziswano kunye nothuthu lwempukane (umzekelo, i-6% yothuthu lwempukane + 6 kg/m³ yefibers) ifezekisa eyona ndlela ifanelekileyo yokuxhathisa kwiqabaka, njengoko uthuthu lwempukane lucokisa ubume bepore ngelixa iintsinga zicinezela ukuqhekeka komkhenkce.
- IiParameters ezingundoqo zokuPhucula
Ubude beFiber: I-24 mm fibers inconywa ukulinganisa amandla kunye nokunyamezela, nangona i-18 mm fibers igqwesa kumandla aguquguqukayo.
Uluhlu lwedosi: 0.1%–0.15% ngokomthamo (okanye 2–6 kg/m³ ngobunzima). Ukugqithiswa kwedosi kuyingozi kwi-fiber agglomeration kunye nokuncipha kokusebenza.
I-Synergistic Materials: I-Synergistic ash (6% -15%) okanye umsi wesilika (6% -9%) uphucula ngakumbi iimpawu zoomatshini kwaye unciphise ilahleko yokungena.
- Iingcebiso zeSicelo
Iimeko: Ilungele iindlela zabahambi ngeenyawo, iiplaza, kunye nemimandla ebandayo efuna zombini ukungena kunye nokomelela.
Ukwakhiwa: Sebenzisa "i-samente-coated aggregate" indlela yokuxuba ukuqinisekisa ukusasazeka kwefayibha efanayo kwaye unqande ukuhlangana.
Isishwankathelo, i-basalt fiber ilungisa i-microstructure kunye nokusebenza komatshini wekhonkrithi evumelekileyo, kodwa ulawulo olungqongqo lwedosi kunye neeparitha zenkqubo zibalulekile ukulinganisela amandla kunye nokunyamezela. Uphando lwexesha elizayo kufuneka lugxininise kwi-fiber surface modification kunye ne-multi-material synergy ukoyisa imida yokusebenza yangoku.
