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 masimende mukongiri uye kuvandudza slump kuchengetedza kuita kwekongiri yekutengesa. Parizvino, air-entraining agent ndechimwe chezvinhu zvinokosha mukutengesa kongiri musanganiswa (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 migumisiro 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%, kongiri yekudzikisa mvura inosvika kupfuura 20% mushure mekuwedzera shoma shoma yemhepo-entraining agent, ndiko kuti, kuderera kwemvura kunowedzera ne4.5%. Pakuwedzera kwe1% kwehuwandu hwemvura, simba rekongiri richawedzera ne2% kusvika 4%. Nokudaro, chero bedzi huwandu hwemhepo-entraining
mumiririri anodzorwa zvakanyanya, kwete chete simba rekongiri harizodzike, asi richawedzera. Nekuda kwekutonga kwemukati wemhepo, miedzo yakawanda yakaratidza kuti mhepo yepasi-yakasimba 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 zvemvura-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.
