Yakakosha tekinoroji uye yehupfumi mabhenefiti emhepo-entraining agent inoshandiswa mukutengesa kongiri
Air-entraining admixture musanganiswa unogona kuburitsa huwandu hukuru hwemabhuru madiki, akakora uye akagadzikana kana akasanganiswa mukongiri.Durability sechando kuramba uye kusamira.Kuwedzerwa kwemhepo-entraining agent kune yekutengeserana kongiri kunogona kudzivirira yechipiri adsorption yeakapararira simende masimendi mukongiri uye inovandudza slump kuchengetedza kuita kwekongiri yekutengesa.Parizvino, air-entraining agent ndechimwe chezvinhu zvinokosha mukutengesa kongiri admixture (mamwe anoderedza mvura uye anodzosa).MuJapan nenyika dzekumadokero, pane inenge isina kongiri isina air-entraining agent.MuJapan, kongiri isina air-entraining agent inonzi yakakosha kongiri (senge permeable kongiri, nezvimwewo).
Air-entraining ichakanganisa simba rekrete, iyo inoreva kumigumisiro yekuedza pasi pemamiriro ekrete uye mvura-simende.Apo mhepo yemhepo inowedzera ne1%, simba rekrete richaderedzwa ne4% kusvika ku6%, uye kuwedzerwa kwemhepo-entraining agent kuchaderedzawo simba rekrete.Mutengo wemvura unowedzera zvakanyanya.Yakaedzwa ne naphthalene-based superplasticizer.Kana kongiri yekudzikisa mvura iri 15.5%, iyo kongiri yekudzikisa mvura inosvika kupfuura 20% mushure mekuwedzera shoma shoma yemhepo-entraining agent, ndiko kuti, kuderera kwemvura kunowedzera ne4.5%.Pamusoro pekuwedzera kwe1% kwehuwandu hwemvura, simba rekongiri richawedzera ne2% kusvika 4%.Nokudaro, chero bedzi huwandu hwemhepo-intraining
mumiririri anodzorwa zvakanyanya, kwete chete simba rekongiri harizodzike, asi richawedzera.Nekuda kwekutonga kwemukati wemhepo, miedzo yakawanda yakaratidza kuti mhepo yemukati yepasi-simba kongiri inodzorwa pa5%, iyo yepakati-yakasimba kongiri inodzorwa pa4% kusvika 5%, uye yakakwirira-yakasimba kongiri inodzorwa pa3. %, uye simba rekongiri harizoderedzwa..Nokuti iyo air-entraining agent ine maitiro akasiyana-siyana pane simba rekrete rine zvakasiyana-siyana mvura-simende ratios.
Tichifunga nezvekudzikisa mvura kweiyo air-entraining agent, kana uchigadzira yekutengeserana kongiri musanganiswa, mai yemvura yemvura inoderedza mumiriri inogona kuderedzwa zvakanyanya, uye hupfumi hunobatsira.
