Mhedzisiro yeBasalt Fiber pakushanda kweConcrete inonyungudika
Basalt faibha, sezvinhu zvitsva zvisingasanganisike, zvinoshanda zvakanyanya, uye zvisingakuvadzi nharaunda, zvinowedzera zvakanyanya hunhu hwemuchina, kugara kwenguva refu, uye mashandiro ekongiri inoyerera mvura. Pazasi pane ongororo yakawanda yemhedzisiro yayo uye magadzirirwo ekugadzirisa:
- Mhedzisiro paZvivakwa zveMichina
Simba Rinosimbaradza uye Rinochinjika
Basalt faibha Kusimbisa simende kunowedzera simba rekudzvanya nekuchinjika kwekongiri inoyerera. Ongororo dzinoratidza kuti mafiber anoumba chimiro che network chine mativi matatu, zvichisimbisa kubatana pakati pema aggregates ne simende paste uku zvichidzivisa kupararira kwe crack. Semuenzaniso:
Simba Rokudzvanya: Nemafiber e12 mm ne24 mm, simba rekudzvanya rinotanga kuwedzera uye rozodzikira kana fiber yakawanda iri mukati. Chiyero chakakodzera i0.1%–0.15% (nehuwandu), uye mafiber e24 mm achisvika pakudzvanya kwepamusoro-soro kwe24.3 MPa (pamuyero we0.1%).
Simba Rokuchinjika: Kureba kwefayibha kune simba guru pakuchinjika kwefayibha. Semuenzaniso, fayibha dze18 mm dzinowedzera simba rekuchinjika kwefayibha ne66.44% zvichienzaniswa nekongiri isina chinhu nekuda kwekubatana kwakawedzerwa pakati pefayibha neaggregate.
Kusimba Kwakawedzerwa uye Ductility
"Mhedzisiro yekubatanidza" ye Basalt Fibers inovandudza kusimba, ichichinja nzira dzekukundikana kubva pakuputsika kuenda pakupfava. Ongororo ye microscopic inoratidza kuti fibers dzinodzikamisa chimiro cheskeleton mukati me simende, zvichidzivirira kukura kwetsekwe.
Mhedzisiro Pakubvumidzwa Kwekubvumidzwa
Kuderedzwa kweKubvumidzwa kweKubvumidzwa
Kubatanidzwa kwefiber kunovhara zvishoma maburi, zvichideredza kupenya kwemvura. Semuenzaniso, kuwedzera huwandu hwefiber kubva pa0.05% kusvika pa0.2% kunoderedza zvishoma nezvishoma kupenya kwemvura, asi kuchiri kusangana nezvinodiwa (semuenzaniso, kupenya kwemvura >1 mm/s pa20% porosity).
Kuenzanisa Porosity uye Fiber Parameters
Matayi marefu (semuenzaniso, 12 mm → 24 mm) anowedzera kuyerera zvishoma asi achiri kuderedza kupenya kwemvura.
Kusanganisa shinda nezvinosanganiswa nemaminerari (semuenzaniso, dota rinobhururuka) kunogadzirisa chimiro cheburi, zvichideredza kurasikirwa kwemvura inopinda muvhu ukuwo kuchichengetedza simba.
- Kuramba Kusina Kunaka kweFrost
Fiber dzebasalt kuwedzera kunaka kwechimiro chemukati, zvichiwedzera zvakanyanya kuramba chando:
Mushure menguva dzechando dzinonyunguduka ka100, sampuli dzakasimbiswa nefiber dzinoratidza kurasikirwa kukuru kwakaderera kusvika ku0.9% uye dzinochengetedza 62.5% relative dynamic elastic modulus.
Kushanda pamwe chete nedota renhunzi (semuenzaniso, 6% dota renhunzi + 6 kg/m³ fibers) kunoita kuti pave nekusagadzikana kwechando zvakanyanya, sezvo dota renhunzi richinatsa chimiro cheburi ukuwo mafekitori achidzivirira kupwanyika kwechando nekunyunguduka.
- Magadzirirwo Ekugadzirisa Makiyi
Kureba kweFiber: Fiber 24 mm dzinokurudzirwa kuti dzisimbise simba uye dzipinde zvakanaka, kunyange hazvo 18 mm fibers dzichigona kusimba zvakanyanya.
Chiyero chemuyero: 0.1%–0.15% nehuremu (kana 2–6 kg/m³ nehuremu). Muyero wakawandisa unokanganisa kuungana kwefiber uye kudzikira kwekushanda.
Zvinhu Zvinoshanda Pamwe Chete: Dota rinobhururuka (6%–15%) kana fume yesilika (6%–9%) zvinowedzera kuwedzera hunhu hwemakanika uye kuderedza kurasikirwa kwemvura inoyerera.
- Mazano Ekushandisa
Mamiriro: Akanakira nzira dzekufamba netsoka, nzvimbo dzekupaka, nenzvimbo dzinotonhora dzinoda kupindira kwemvura uye simba.
KuvakaShandisa nzira yekusanganisa "aggregate yakaputirwa nesimende" kuti uve nechokwadi chekuti fiber inopararira zvakaenzana uye kudzivirira kuungana.
Muchidimbu, basalt fiber inovandudza magadzirirwo ekongiri inoyerera mvura uye mashandiro ayo, asi kudzora zvakanyanya mwero wemushonga uye magadzirirwo emushonga kwakakosha kuti simba rienzane uye kupindira kwemvura zvienzane. Ongororo yeramangwana inofanira kutarisa pakugadzirisa fiber pamusoro uye kubatana kwezvinhu zvakawanda kuti ikunde zvipingamupinyi zvekushanda kwayo pari zvino.
