Aluminate simende, inozivikanwawo seyepamusoro-alumina simende (HAC), imhando ye hydraulic simende inogadzirwa kubva ku bauxite uye limestone. Yakatanga kuwanikwa muFrance kuma1900 uye iko zvino yave kushandiswa zvakanyanya mukuvaka nekuda kwezvivakwa zvayo zvakasiyana uye zvakanakira kupfuura mamwe marudzi esimende. Muchinyorwa chino, tichaongorora kwakabva, hunhu, zvakanakira, uye mashandisiro ealuminate simende.

Origins Aluminate simende yakatanga kuwanikwa muFrance mukutanga kwema1900 nainjiniya wekuFrance ainzi Jules Bied. Akaona kuti nokupisa musanganiswa we<em>bauxite ne<em>limestone pakupisa kukuru, simende yaigadzirwa yaiva nesimba rakawanda uye yakasimba. Ichi chinyorwa pakutanga chaizivikanwa se "ciment fondu" kana "simende yakanyungudutswa" muchiFrench, uye yakazopihwa patent seyepamusoro-alumina simende.

Hunhu Aluminate simende ine akati wandei akasiyana maitiro anoita kuti ive yakasiyana nemamwe marudzi esimende. Aya maitiro anosanganisira:

1. Kurumidza kuseta: Aluminate simende inogadzika nekukurumidza, ine nguva yekumisikidza yeakapoteredza 4-5 maawa. Izvi zvinoita kuti ive yakanakira zvikumbiro panodiwa kuseta nekukurumidza, senge mukutonhora kwemamiriro ekunze kana kana kugadzirisa nekukurumidza kuchidikanwa.
2. Kusimba kwekutanga kwekutanga: Simende yeAluminate ine simba rekutanga rekutanga, iine simba rekumanikidza rinotenderedza 50-70 MPa mushure mezuva rimwe rekurapa. Izvi zvinoita kuti ive yakanakira zvikumbiro panodiwa simba rekutanga, senge precast kongiri kana kugadzirisa.
3. Kupisa kwakanyanya kwe hydration: Simende yeAluminate inogadzira huwandu hwekupisa panguva ye hydration process, izvo zvinogona kuve zviri zviviri zvakanakira uye zvisingabatsiri. Uku kupisa kwakanyanya kwe hydration kunoita kuti ive yakakodzera kushandiswa mukutonhora kwemamiriro ekunze, sezvo ichigona kubatsira kukurumidza kurapa. Nekudaro, zvinogona zvakare kutungamira mukutsemuka uye mamwe marudzi ekukuvadza kana zvikasagadziriswa nemazvo.
4. Yakaderera kabhoni tsoka: Aluminate simende ine yakaderera kabhoni tsoka pane yechinyakare Portland simende, sezvo ichida yakadzika tembiricha panguva yekugadzira uye ine shoma clinker.

Advantages Aluminate simende inopa akawanda mabhenefiti pamusoro pemamwe marudzi esimende, anosanganisira:

1. Kurumidza kuseta: Aluminate simende inogadzika nekukurumidza, iyo inogona kuchengetedza nguva uye kuderedza mari yekuvaka.
2. Kusimba kwekutanga kwekutanga: Aluminate simende ine yakakwira simba rekutanga, iyo inogona kuderedza nguva inodiwa pakurapa uye kuwedzera chibereko.
3. High sulfate resistance: Aluminate simenti ine kupikisa kwakanyanya kurwisa sulfate, iyo inoita kuti ive yakakodzera kushandiswa munzvimbo dzine sulfate yakakwira, senge nzvimbo dzemahombekombe.
4. Yakaderera shrinkage: Aluminate simende ine yakaderera shrinkage mwero pane yechinyakare Portland simende, izvo zvinogona kuderedza njodzi yekutsemuka uye mamwe maitiro ekukuvadza.

Inoshandisa Aluminate simende inoshandiswa mumhando dzakasiyana dzekushandisa, kusanganisira:

1. Rapid-setting kongiri: Aluminate simende inowanzo shandiswa mumashandisirwo panodiwa kuseta nekukurumidza, senge mukutonhora kwekunze kana kugadzirisa nekukurumidza.
2. Precast kongiri: Aluminate simende inowanzo shandiswa mukugadzira precast kongiri zvigadzirwa, senge makongiri pombi, slabs, uye mapaneru.
3. Refractory simende: Aluminate simende inowanzo shandiswa mukugadzira simende inodzoreredza, iyo inoshandiswa kumisa moto unopisa kwazvo, kilns, uye zvimwe zvigadzirwa zvemaindasitiri.
4. Specialized application: Aluminate simende inoshandiswawo muhunyanzvi maapplication, senge mukugadzirwa kwekongiri inozvimisikidza uye sebhainda mune mamwe marudzi emidziyo yemazino.

Mhedziso Aluminate simende imhando yakasarudzika yesimende inopa akawanda mabhenefiti pamusoro pechinyakare Portland simende. Iyo ine yakaderera kabhoni tsoka, inogadzika nekukurumidza, ine yakakwira simba rekutanga, uye inopikisa zvakanyanya kurwisa sulfate. Aluminate simende inoshandiswa mumhando dzakasiyana-siyana, kusanganisira kukurumidza-kugadzika kongiri, precast kongiri, refractory simende, uye hunyanzvi hwekushandisa senge zvinhu zvemazino. Nepo aluminate simende ine zvakawanda zvakanakira, zvakakosha kuti uzive kuti inewo zvimwe zvakaipira izvo zvinofanirwa kutariswa. Kupisa kwakanyanya kwe hydration kunogona kutungamirira kukuputika uye mamwe maitiro ekukuvadza kana kusina kutarisirwa zvakanaka, uye inogonawo kudhura kudarika tsika yePortland simenti. Nekudaro, mabhenefiti ekushandisa aluminate simende anowanzo pfuura mutengo, kunyanya mumashandisirwo ane hunyanzvi uko hunhu hwayo hwakasiyana hunodiwa.
