Mhedzisiro yeBasalt Fiber paKuita kwePermeable Concrete

Basalt fiber, serinoveli inorganic, yakakwirira-kuita, uye eco-inoshamwaridzika zvinhu, inosimudzira zvakanyanya mashandiro emakanika, kusimba, uye kushanda kwekongiri inopindika. Pazasi pane multidimensional kuongororwa kwemaitiro ayo uye optimization paramita:

1. Impact paMechanical Properties

Yakavandudzwa Compressive uye Flexural Simba

   Basalt fiber kusimbisa zvinobudirira kunowedzera kusimba uye kushanduka kwesimba repermeable kongiri. Zvidzidzo zvinoratidza kuti mafibers anoumba matatu-dimensional network chimiro, achisimbisa chisungo pakati peaggregates nesamende paste uku ichidzivirira kutsemuka. Semuyenzaniso:

Compressive Strength: Iine 12 mm uye 24 mm fiber, simba rekumanikidza rinotanga rinowedzera uye rinodzikira nepamusoro fiber content. Iyo yakakwana dosage ndeye 0.1% -0.15% (nehuwandu), ine 24 mm fibers inowana peak compressive simba ye24.3 MPa (pa0.1% dosage).

Flexural Strength: Fiber kureba kune zvakanyanya kutaurwa mhedzisiro pane flexural simba. Semuyenzaniso, 18 mm faibha dzinowedzera flexural simba ne 66.44% zvichienzaniswa nekongiri isina kujeka nekuda kwekunatsiridzwa kwekubatana kwemukati kubva pakuwedzera fiber-aggregate kusangana.

Enhanced Toughness uye Ductility

Iyo "bhiriji mhedzisiro" ye Basalt Fibers inovandudza kuoma, kushandura kutadza modes kubva kune brittle kuenda kune ductile. Ongororo yeMicroscopic inoratidza kuti mafiibhi anodzikamisa skeleton chimiro mukati mesamende matrix, zvichivharira mutswe kukura.

Impact paPermeability

Yakaderedzwa Permeability Coefficient

Fiber incorporation inovhara zvishoma pores, ichidzikisa permeability. Semuenzaniso, kuwedzera fiber content kubva 0.05% kusvika 0.2% zvishoma nezvishoma inoderedza permeability coefficient, asi ichiri kusangana nezvinodiwa (semuenzaniso, permeability> 1 mm / s pa 20% porosity).

Kuenzanisa Porosity uye Fiber Parameters

Mafiibha akareba (semuenzaniso, 12 mm → 24 mm) anowedzera porosity zvishoma asi achiri kuderedza kupera.

Kubatanidza mafiber nemamineral admixtures (semuenzaniso, nhunzi ash) inogonesa chimiro chepore, kuderedza kupera kwekurasikirwa uku uchichengetedza simba.

3. Kuvandudzwa kweFrost Resistance

Basalt fibers kuwedzera kutendeseka kwemukati, kuwedzera zvakanyanya kusimba kwechando:

Mushure memazana zana echando-inonyungudutswa, zvienzaniso zvakasimbiswa-fiber zvinoratidza kurasikirwa kukuru kwakaderera se0.9% uye kuchengetedza 62.5% hama ine simba elastic modulus.

Synergy ine madota enhunzi (semuenzaniso, 6% fly ash + 6 kg/m³ fibers) inogonesa kumira nechando, sezvo madota enhunzi anonatsa pore pore mafiber achidzvanya kuputika kwechando.

4. Key Optimization Parameters

Fiber Length: 24 mm fibers inokurudzirwa kuti ienzanise simba uye kupera, kunyange zvazvo 18 mm fibers inopfuura mukushanduka kwesimba.

Dosage Range: 0.1%–0.15% nehuwandu (kana 2–6 kg/m³ nehuremu). Yakawandisa dosage ine njodzi fiber agglomeration uye kuderedzwa kushanda.

Synergistic Materials: Fly ash (6% -15%) kana silica fume (6% -9%) inowedzera kuwedzera ma mechanical properties uye kuderedza permeability kurasikirwa.

5. Zvikumbiro zveMashandisirwo

Scenarios: Yakanakira nzira dzevanofamba netsoka, maplaza, uye nzvimbo dzinotonhora dzinoda zvese kupenya uye simba.

Kuvaka: Shandisa iyo "simende-yakavharidzirwa aggregate" nzira yekusanganisa kuti uve nechokwadi chekupararira kwefiber uye kudzivirira kudhumhana.

Muchidimbu, basalt fiber inokwidziridza iyo microstructure uye mechanic performance yepermeable kongiri, asi kudzora kwakasimba kwedosi uye maitiro ma paramita akakosha kuenzanisa simba uye permeability. Tsvagiridzo yeramangwana inofanirwa kutarisisa pane fiber pamusoro pekugadzirisa uye akawanda-material synergy kukunda zvazvino kuita zvisingakwanisi.
