Kusimbisa Ramangwana: Kuongorora Zvinowedzera Zvinowedzera muConcrete Construction

Kugadzira yakasimba uye yakakwirira-inoshanda kongiri zvimiro zvinotsamira zvakanyanya pakusarudzwa kwezvekuwedzera, izvo zvinotora basa rakakosha mukusimudzira kongiri zvivakwa. Izvi zvekuwedzera, zvakaita sedota renhunzi, cenospheres, yakawedzera perlite, hollow girazi microspheres, kongiri fibers, uye maajenti ekuderedza mvura, ari kushandura indasitiri yekuvaka nekuvandudza misanganiswa yekongiri uye admixtures. Ichi chinyorwa chine chinangwa chekuongorora zvimiro uye mabasa ezviwedzere zvekuwedzera izvi, zvichiratidza kukosha kwazvo pakuita kwekongiri.

Fly ash , a byproduct yekupisa marasha, inoshandiswa zvakanyanya mukugadzira kongiri nekuda kweiyo pozzolanic properties. Iyo inosimudzira kongiri simba, kusimba, uye kushanda nesimba uku ichideredza kupisa kwe hydration. Nekutsiva chikamu chesimende,kubhururuka madota inosimudzira maitiro ekuvaka akasimba nekudzikisa iyo carbon footprint. Yayo yakanaka particle size uye spherical shape inosimudzira kongiri kurongedza density, zvichitungamira mukudzikira permeability uye nekuvandudza kuramba mamiriro ezvakatipoteredza uye makemikari anokanganisa.

Cenospheres , lightweight hollow ceramic microspheres inotorwa kubva kunhunzi dota, iri kuwedzera kuzivikanwa sezvinowedzera zvakasiyana-siyana mukugadzira kongiri. Density yavo yakaderera uye spherical shape inobatsira mukuderedza density yekongiri, ichiita kuti ive yakakodzera kune maapplication anoda lightweight zvimiro. Uyezve,cenospheres kunatsiridza zvivakwa zvekongiri zvinopisa, zvichiita kuti ive yakanaka kune mapurojekiti ekuvaka asingashande nesimba.

Yakawedzerwa perlite , girazi rinoputika rinoputika, rinokanganisa zvakanyanya zvinhu zvekongiri. Huremu hwayo uye hunhu hunodzivirira hunodzora kongiri uku uchiwedzera kudzivirira kwemoto uye kuita kwekupisa. Incorporatingyakawedzera perlite mumisanganiswa yekongiri inokonzeresa zvivakwa zvinogara uye zvinoshandisa simba, zvichiita kuti ive sarudzo inosarudzika yezvivakwa zvinogara zviripo.

Hollow girazi microspheres , akagadzirwa lightweight particles ane high compressive simba, ari kuumbazve kongiri tekinoroji. Aya ma microspheres anovandudza kongiri musanganiswa kushanda, kuderedza density, uye kuwedzera kupisa kwekupisa. Chimiro chadzo chakatenderera uye yakaderera yekupisa yekupisa inoita kuti ive yakanakira kugadzira yakakwirira-inoshanda lightweight kongiri ine yakagadziridzwa kusimba uye kushanda nesimba.

Concrete fibers , kusanganisira simbi, synthetic, uye zvisikwa zvakasiyana-siyana, zvinoshanda sekusimbisa zvinowedzera zvinowedzera kongiri kusimba uye kusimba. Simbi fibers inosimudzira kongiri yekupwanya kuramba uye ductility, ichiita kuti ive yakakodzera maindasitiri uye zvivakwa zvekushandisa.Synthetic fibers , senge polypropylene nenylon, inosimudzira kongiri kukanganisa kuramba uye kusimba, kunyanya munzvimbo dzine vanhu vakawanda. Faibha dzechisikigo senge jute nekokonati dzinopa sarudzo dzakasimba dzekusimbisa uku ichideredza kuburitsa kabhoni mukugadzirwa kwekongiri.

Zvishandiso zvinoderedza mvura , inozivikanwawo se superplasticizers, zvakakosha zvekuwedzera zvinowedzera kongiri musanganiswa kushanda uye kuyerera pasina kukanganisa simba. Nekuparadzira zvimedu zvesimende zvakanyanya, vamiririri vekudzikisa mvura vanogonesa kugadzirwa kwekongiri yakasimba-yakasimba ine mvura yakaderedzwa. Izvi zvinotungamira kusimba rakagadziridzwa, kuderedzwa permeability, uye kukwidziridzwa kwepamusoro kupera, zvichiita kuti ive chinhu chakakosha muhunyanzvi hwemazuva ano kongiri.

Muchidimbu, mashandisirwo matsva ezvekuwedzera kongiri, zvinosanganisira dota renhunzi, cenospheres, yakawedzera perlite, hollow girazi microspheres, kongiri fiber, uye ekuderedza mvura vamiririri, iri kushandura kongiri maitiro ekuvaka. Izvi zvinowedzera kwete chete zvinongowedzera kongiri musanganiswa zvivakwa asiwo zvinobatsira kune inoenderera uye ine simba-inoshanda kuvaka maitiro. Sezvo indasitiri yekuvaka ichifambira mberi, kubatanidzwa kweizvi zvekuwedzera zvekuwedzera kucharamba kuchiita basa rakakosha mukuumba ramangwana rekongiri tekinoroji, kufambisa kuvandudzwa kwezvivakwa zvinogara, zvinosimba, uye zvine hushamwari.
