Impembelelo yeBasalt Fiber ekusebenzeni kweConcrete eVulekayo

Ifayibha yeBasalt, njengesixhobo esitsha esingabonakaliyo, esisebenza kakuhle, nesinobuhlobo nokusingqongileyo, siphucula kakhulu iipropati zoomatshini, ukuqina, kunye nokusebenza kwekhonkrithi ekwaziyo ukungena. Apha ngezantsi kukho uhlalutyo olunemilinganiselo emininzi yempembelelo yayo kunye neeparameter zokuphucula:

1. Impembelelo kwiipropati zoomatshini

Ukuphucula Amandla Okucinezela Nokuguquguquka

   Ifayibha yeBasalt Ukuqinisa kuphucula ngokufanelekileyo amandla okuxinzelela kunye nokugoba kwekhonkrithi edlulayo. Izifundo zibonisa ukuba iifayibha zenza isakhiwo senethiwekhi esinemilinganiselo emithathu, siqinisa ukubopha phakathi kwee-aggregates kunye ne-samente paste ngelixa sithintela ukwanda kweentanda. Umzekelo:

Amandla Okucinezela: Ngeefayibha eziyi-12 mm kunye ne-24 mm, amandla okucinezela ayanda ekuqaleni aze anciphe xa kukho ifayibha ephezulu. Umlinganiselo ofanelekileyo yi-0.1%–0.15% (ngokomthamo), apho iifayibha eziyi-24 mm zifikelela kumandla okucinezela aphezulu angama-24.3 MPa (kwidosi eyi-0.1%).

Amandla Okugobeka: Ubude befayibha bunefuthe elibonakalayo kumandla okugobeka. Umzekelo, iifayibha eziyi-18 mm zonyusa amandla okugobeka nge-66.44% xa kuthelekiswa nekhonkrithi ecacileyo ngenxa yokuqina kokubopha phakathi kwefacial ngenxa yokwanda koqhagamshelwano lwefayibha-edibeneyo.

Ukuqina Okuphuculweyo kunye Nokuguquguquka

"Isiphumo sokuhlanganisa" I-Basalt Fibers iphucula ukuqina, itshintsha iindlela zokungaphumeleli ukusuka kwi-brittle ukuya kwi-ductile. Uhlalutyo lwe-Microscopic lubonisa ukuba iifayibha zizinzisa ulwakhiwo lwamathambo ngaphakathi kwe-matrix yesamente, zithintela ngempumelelo ukukhula kweentanda.

Impembelelo ekuvumelekeni kokuphila

Umlinganiselo Wokuvunyelwa Kokuncitshiswa

Ukufakwa kwefayibha kuthintela kancinci iimbobo, kunciphisa ukuvuleka. Umzekelo, ukonyusa umxholo wefayibha ukusuka kwi-0.05% ukuya kwi-0.2% kunciphisa kancinci kancinci ukuvuleka, kodwa kusahlangabezana nemimiselo (umz., ukuvuleka >1 mm/s kwi-20% yokuvuleka).

Ukulinganisela iiParameters zePorosity kunye neFiber

Iifayibha ezinde (umz., 12 mm → 24 mm) zonyusa kancinci ukuvuleka kwesikhumba kodwa zisehlisa ukuvuleka kwesikhumba.

Ukudibanisa imicu kunye nezimbiwa ezixutyiweyo (umz., uthuthu oluphumayo) kuphucula ulwakhiwo lwemingxunya, kunciphisa ukulahleka kokungena kwamanzi ngelixa kugcinwa amandla.

3. Ukuphucula Ukumelana neNqabaka

Iifayibha zeBasalt ukuphucula ukuqina kwesakhiwo sangaphakathi, okwandisa kakhulu ukumelana nomkhenkce:

Emva kwemijikelo yokuqandisa i-100, iisampuli eziqiniswe ngefayibha zibonisa izinga lokulahleka kobunzima eliphantsi njenge-0.9% kwaye zigcina i-62.5% ye-relative dynamic elastic modulus.

Ukusebenzisana nothuthu lwempukane (umz., uthuthu lwempukane oluyi-6% + iifayibha eziyi-6 kg/m³) kufezekisa ukuxhathisa iqabaka, njengoko uthuthu lwempukane lucoca isakhiwo seembobo ngelixa iifayibha zithintela ukuqhekeka kokuqandusela nokunyibilika.

4. Iiparamitha zoLungiselelo oluPhambili

Ubude beFiber: Iifayibha ezingama-24 mm ziyacetyiswa ukuze kulinganiswe amandla kunye nokuvuleka, nangona iifayibha ezili-18 mm zigqwesile ngamandla okugoba.

Uluhlu lweMilinganiselo: 0.1%–0.15% ngokomthamo (okanye 2–6 kg/m³ ngobunzima). Umlinganiselo ogqithisileyo ubeka emngciphekweni ukuhlanganiswa kwefayibha kunye nokusebenza okunciphileyo.

Izinto ezihambelanayo: Uthuthu oluphaphazelayo (6%–15%) okanye i-silica fume (6%–9%) ziyaphucula ngakumbi iimpawu zoomatshini kwaye zinciphise ukulahleka kokungena kwamanzi.

5. Iingcebiso zeSicelo

Imeko: Ifanelekile kwiindawo zokuhamba ngeenyawo, kwiindawo ezibanzi, nakwiindawo ezibandayo ezifuna ukungena kwamanzi kunye namandla.

UlwakhiwoSebenzisa indlela yokuxuba "i-aggregate egqunywe ngesamente" ukuqinisekisa ukusasazeka kwefayibha ngokulinganayo kwaye uphephe ukuxinana.

Ngamafutshane, i-basalt fiber iphucula ulwakhiwo lwe-microstructure kunye nokusebenza koomatshini kwekhonkrithi enokutyibilika, kodwa ulawulo oluqinileyo lwemilinganiselo kunye neeparameter zenkqubo lubalulekile ukulinganisela amandla kunye nokutyibilika. Uphando lwexesha elizayo lufanele lugxile ekuguqulweni komphezulu wefayibha kunye nokusebenzisana kwezinto ezininzi ukuze koyiswe imida yokusebenza yangoku.
