Izithasiselo zikakhonkolo ezingasindi | Ama-ejenti Akhipha Amagwebu Asebenza Kakhulu Wokhonkolo Weselula
Ukwakhiwa kwamakhemikhali we-ejenti yokugwedla kubalulekile ekunqumeni ukusebenza kokhonkolo. I-chemistry ye-ejenti egwebuzelayo ingathinta izakhiwo zemishini kanye ne-thermal conductivity yekhonkrithi.
Isilinganiso samanzi kusimende (w/c) kunomthelela omkhulu ku-microstructure yekhonkrithi ye-foam. Uma isilinganiso se-w/c singaphansi komkhawulo ofanele, kwakheka amagwebu anezindonga ezincane nezingajwayelekile, okwenza amandla okucindezela kakhonkolo ehle. Ngokungqubuzanayo, lapho isilinganiso se-w/c singaphezu komkhawulo ofanele, amagwebu kulula ukuhlangana futhi kwakheka izimbotshana ezinkudlwana.
Ama-Superplasticizers avame ukusetshenziswa kukhonkolo wegwebu ukunciphisa isilinganiso samanzi kusimende, futhi ugcine uketshezi olwanelisayo ngesikhathi sokukhiqizwa kwegwebu. Lokhu kunciphisa isidingo samanzi, kuthuthukisa ukusebenza futhi kwandisa amandla okucindezela ukhonkolo wegwebu.
Fly umlotha [41] ingasetshenziswa futhi ku-foam ukhonkolo ukuze kuthuthukiswe ukusebenza kwayo kanye ne-conductivity yokushisa. Ukusebenzisana phakathi komlotha wempukane kanye ne-ejenti ekhihliza amagwebu kungathuthukisa amandla ayo acindezelayo kanye nokwakheka kwezimbotshana, njengoba kuboniswe esifundweni. Ngaphezu kwalokho, ukufakwa komlotha wezimpukane ezimahhadla kukhonkolo wegwebu kungaholela kusayizi omncane wembotshana namandla okucindezela aphezulu.
Imicu ingabuye yengezwe kukhonkolo yegwebu ukuze kwenyuswe izinga lokumuncwa kwamanzi. Imicu efana ne-sugar pulp fibers inamandla amakhulu okumunca amanzi kunesihlabathi, ngakho-ke zinganezelwa kukhonkolo yegwebu ukuze kwandiswe ukusebenza kwayo namandla.
Ukuzinza kukakhonkolo weselula ongasindi kuncike ohlotsheni lweqoqo elisetshenzisiwe. Ukusebenzisa i-aggregate kakhonkolo egaywe kabusha esikhundleni sesihlabathi esicolekile kungathuthukisa kakhulu ukuzinza kukakhonkolo weselula ongasindi.
