Concrete admixtures, inonzi admixtures kwenguva pfupi, inoreva zvinhu zvakawedzerwa zvisati zvaitika kana panguva yekusanganiswa kwekongiri kuvandudza zvimiro zvekongiri nyowani uye / kana yakaoma kongiri. Hunhu hwekongiri admixtures akawanda marudzi uye
diki dosage, iyo inoita basa rakakosha mukugadzirisa kongiri. Nekuvandudzwa zvishoma nezvishoma kweindasitiri yekuvaka, kudiwa kwekongiri mumapurojekiti einjiniya kuri kuramba kuchiwedzera, uye panguva imwe chete, kune zvakakwirira zvinodiwa pakuita uye kunaka kwekongiri. Muchirevo chechinyorwa chino, sechinhu chakakosha cheinjiniya chinogona kusimudzira zvakanyanya kuita kwekongiri, kongiri yakasanganiswa yave chinhu chakakosha chechishanu mukongiri yemazuva ano kunze kwesimende, jecha, dombo nemvura.
Yepamusoro-inoshanda-inoderedza mvura Mumiriri wemvura inoderedza zvakanyanya kukamurwa muzvikamu zvitatu: yakajairwa yekudzikisa mvura, yakanyanya-inoshanda yekudzikisa mvura uye yepamusoro-inoshanda yekudzikisa mvura. Kubudirira kwe superplasticizers kwapfuura nematanho matatu: chizvarwa chekutanga cheakajairika superplasticizers anomiririrwacalcium yemiti, chizvarwa chechipiri che superplasticizers inomiririrwa nenaphthaleneseries, uye chizvarwa chechitatu che superplasticizers inomiririrwa napolycarboxylate superplasticizerseries. Chizvarwa chepamusoro-inoshanda superplasticizer nhanho.Polycarboxylate superplasticizerine zvakanakira kuderera muyero uye kuderedzwa kwemvura yakakwirira, uye inogona kushandiswa kugadzira yakakwirira-simba, ultra-yakakwirira-simba, yakakwirira-kugara uye super-fluid kongiri; Iyo nzira haina mvura yekurasa, gasi remarara, tsvina yakasara yekuburitsa uye zvimwe zvinhu. Iyo yakasvibira uye inoshamwaridzana nepamusoro-inoshanda yekudzikisa mvura mumiriri, uye ine mabhenefiti ari pachena mukuchengetedza kwezvakatipoteredza uye kugona. Nekuwedzera kwesimba rekugadzira uye kuvandudzwa kwepermeability, mapolycarboxylate superplasticizers ave iwo makuru emhando dze superplasticizers anogadzirwa uye anopedzwa munyika yangu.
Muchirevo che "kukura kwakadzikama" kunotarisirwa kuramba kuchipisa, kuwedzera kwekudiwa kwekongiri kwakaunzwa nekuwedzera kwekuronga mapurojekiti makuru einjiniya uye kufambira mberi kwechirongwa chekuvaka kuchawedzera kudiwa kwekongiri admixtures. nguva imwe chete. Pamusoro pezvo, maererano nemishumo yebasa rehurumende yakapihwa nemapurovhinzi akasiyana, kuvaka zvivakwa zvakaita sezvekufambisa uye mapurojekiti ekuchengetedza mvura anotora chikamu chikuru chezvirongwa zvikuru, uye mapurojekiti ataurwa pamusoro ane hunyanzvi hwekuita kwekongiri, uye mvura inoshanda zvakanyanya. ma reducers anodiwa kuti asangane nezvinodiwa zvekongiri. Kuenzaniswa nemamwe marudzi emusanganiswa, iyo yekupomba yekuvaka inodiwa uye kudzikiswa kwekudedera uye kunyangwe zvishuwo zvisingaite zvemapurojekiti akakosha ekongiri zvine zvakanakira. Naizvozvo, chikamu chekudiwa kweakanyanya-kuita-anodzikisa mvura-anoshanda anogona kuwana "akagadzirwa-akagadzirwa" mapurojekiti einjiniya anotarisirwa kuwedzera mberi.
Bhizinesi reJufu Chemical Kambani rinoshanda kunze kweiyo bhizinesi guru re superplasticizers rinoratidza zviri pasi pechigadzirwa logic iyo yakasiyana zvakanyanya nevakwikwidzi vayo. Mune ramangwana, ichakwanisa kudzokorodza kubudirira kwebhizinesi re superplasticizer, uye nzvimbo yemusika sirin'i yakakwira zvakanyanya kupfuura iyo superplasticizers.
