Izongezo zeConcrete eziKhala | Ii-Agents eziFoaming eziSebenza ngokuPhezulu kwiSellula Concrete
Ikhonkrithi yenye yezinto zokwakha ezisetyenziswa ngokuqhelekileyo, kwaye ibikho kangangamawaka eminyaka. Nangona kunjalo, iimpawu zayo zingaphuculwa ngokongezwa kweekhemikhali ezahlukeneyo, kuquka izongezo eziphathekayo.

Enye yeenzuzo eziphambili zokongeza izongezo zekhonkrithi kukuba zinokunceda ekuphuculeni amandla okufakelwa kwezinto. Izongezo zekhonkrithi ezifana nesamente yasePortland, lamoni, kunye ne-admixtures efana ne-silicates okanye i-aggregate inokunyusa umgangatho we-thermal conductivity, okuthetha ukuba kuya kuba ngcono ekulawuleni ubushushu ngaphakathi kwesakhiwo.
Umzekelo, I-samente yasePortland luhlobo lwesamente oluqulethe umlinganiselo ophezulu we-limestone. Ilitye likalikalika laziwa ngokukwazi ukufunxa nokugcina ubushushu, ukuyenza ibe yimathiriyeli egqwesileyo ngeenjongo zokugquma. Ngokongeza i-samente yasePortland kumxube wekhonkrithi, unokunyusa ubuninzi be-thermal mass kwizinto eziphathekayo, nto leyo eya kunceda ukunciphisa imfuno yokufudumeza nokupholisa kwisakhiwo.
Ikalika sesinye isongezelelo sekhonkrithi esisebenzayo esinokuphucula ukusebenza kwe-insulation. Ikalika yikhemikhali edibana namanzi ukuze ivelise icalcium hydroxide, eyenza umaleko kumphezulu wekhonkrithi. Olu luhlu lunceda ukugquma izinto ngokunciphisa ukuhamba komoya kunye nokuthintela ukuhanjiswa kobushushu.
Imixube efana ne-silicates kunye ne-aggregate nayo iluncedo ekuphuculeni ukusebenza kwe-insulation. I-silicates ziiminerali eziqulethe ixabiso elincinci le-oksijini kunye nekhabhoni, enokuphucula ukuqina kwemixube ekhonkrithi. I-aggregate, kwelinye icala, inikeza inkxaso yesakhiwo kwaye inceda ukusabalalisa ubunzima kwisakhiwo sonke, enokuphucula ukuzinza ngokubanzi kwesakhiwo.

Ukuququmbela, ukongeza izongezo zekhonkrithi kumxube wekhonkrithi unokuba nempembelelo enkulu ekusebenzeni kwayo kwe-insulation. Ngokwandisa i-thermal conductivity yezinto eziphathekayo, ukuphucula amandla kunye nokuqina kwesakhiwo, kunye nokusabalalisa ubunzima kwisakhiwo sonke, ezi zongezo zinokunceda ukunciphisa ukusetyenziswa kwamandla kwaye zenze izakhiwo zikhululeke kwaye zisebenzise amandla. Nangona kunjalo, kubalulekile ukukhetha iintlobo ezifanelekileyo zezongezo kunye nokulandela iinkqubo ezifanelekileyo zokuvavanya ngaphambi kokuzibandakanya kumxube wekhonkrithi ukuqinisekisa iziphumo ezilungileyo..
