Ukuqinisa iKamva: Ukuphonononga izongezo eziQalayo kuLwakhiwo lweConcrete
Ukwakha izakhiwo zekhonkrithi ezihlala ixesha elide kunye nokusebenza okuphezulu kuxhomekeke kakhulu ekukhetheni izongezo, ezidlala indima ebalulekileyo ekuphuculeni iipropati eziphathekayo. Ezi zongezo, ezifana nothuthu lwempukane, i-cenospheres, i-perlite eyandisiweyo, i-microspheres yeglasi engenanto, iifiber zekhonkrithi, kunye nee-arhente zokunciphisa amanzi, ziguqula ishishini lokwakha ngokuphucula imixube yekhonkrithi kunye ne-admixtures. Eli nqaku lijonge ukuphonononga iipropati kunye nemisebenzi yezi zongezo ezitsha, ukugqamisa impembelelo yazo ebalulekileyo ekusebenzeni kwekhonkrithi.
Bhabha uthuthu , i-byproduct yokutsha kwamalahle, isetyenziswa ngokubanzi kwimveliso yekhonkrithi ngenxa yeempawu zayo ze-pozzolanic. Yongeza amandla ekhonkrithi, ukuqina, kunye nokusebenza ngelixa inciphisa ubushushu be-hydration. Ngokufakela inxenye yesamente endaweni yayo.bhabha uthuthu ikhuthaza izenzo zokwakha ezizinzileyo ngokunciphisa i-carbon footprint. Ubungakanani bayo besuntswana elilungileyo kunye nokumila okungqukuva kwandisa ukuxinana kwekhonkrithi, okukhokelela ekunciphiseni ukunyanzeliswa kunye nokuphucula ukuchasana neemeko zokusingqongileyo kunye nabahlaseli beekhemikhali.
IiCenospheres , ii-microspheres ze-ceramic ezingenanto ezikhaphukhaphu ezithathwe kuthuthu lwempukane, ziya ziqondwa ngakumbi njengezongezo eziguquguqukayo kwimveliso yekhonkrithi. Ubuninzi babo obuphantsi kunye nokumila kwe-spherical negalelo ekunciphiseni ukuxinana kwekhonkrithi, okwenza kube yinto efanelekileyo kwizicelo ezifuna izakhiwo ezikhaphukhaphu. Ngaphezu koko,iicenospheres ukuphucula iimpawu zokugquma kwe-thermal zekhonkrithi, ziyenze ilungele iiprojekthi zokwakha ezonga amandla.
I-perlite eyandisiweyo , iglasi yentaba-mlilo eyenzeke ngokwemvelo, inempembelelo enkulu kwiimpawu zekhonkrithi. Iimpawu zayo ezilula kunye ne-insulating zinciphisa ubuninzi bekhonkrithi ngelixa uphucula ukuxhathisa umlilo kunye nokusebenza kwe-thermal. Ukudibanisaperlite eyandisiweyo kwimixube yekhonkrithi iphumela kwizakhiwo ezomeleleyo kunye nezonga amandla, nto leyo eyenza kube lolona khetho lukhethwayo kwiinzame zokwakha ezizinzileyo.
Iimicrosphere zeglasi ezingenanto , amasuntswana enziwe ngobunjineli obukhaphukhaphu anamandla acinezelayo aphezulu, abumba ngokutsha iteknoloji yekhonkrithi. Ezi microspheres ziphucula ukusebenza komxube wekhonkrithi, ukunciphisa ukuxinana, kunye nokwandisa ukugquma kwe-thermal. Ubume bazo obungqukuva kunye nokuhanjiswa kwe-thermal ephantsi kubenza balungele ukuvelisa ikhonkrithi esebenza ngokukhaphukhaphu ephezulu enokuqina okuphuculweyo kunye nokusebenza kakuhle kwamandla.
Iintsinga zekhonkrithi , kubandakanywa intsimbi, i-synthetic, kunye neentlobo ezahlukeneyo zendalo, zisebenza njengezongezelelo eziqinisa amandla ekhonkrithi kunye nokuqina. Iintsinga zentsimbi zongeza ukuxhathisa kokuqhekeka kwekhonkrithi kunye nokudumba, nto leyo iyenza ilungele ukusetyenziswa kwemizi-mveliso kunye neziseko zophuhliso.Iintsinga zokwenziwa , ezifana ne-polypropylene kunye ne-nylon, ziphucula ukuchasana kwempembelelo yekhonkrithi kunye nokuqina, ngokukodwa kwiindawo ezinabantu abaninzi. Iintsinga zendalo ezifana nejute kunye nekokonathi zibonelela ngeendlela ezizinzileyo zokuqinisa ngelixa zinciphisa ukukhutshwa kwekhabhoni kwimveliso yekhonkrithi.
Iiarhente zokunciphisa amanzi , ezikwabizwa ngokuba zii-superplasticizers, zizongezo ezibalulekileyo ezenza umxube wekhonkrithi usebenze kakuhle kunye nokuhamba ngaphandle kokuthomalalisa amandla. Ngokusasaza iinqununu zesamente ngokufanelekileyo, ii-agent zokunciphisa amanzi zivumela ukuveliswa kwekhonkrithi ephezulu kunye nokunciphisa amanzi. Oku kukhokelela ekuphuculweni kokuqina, ukuncitshiswa kokungena, kunye nokuqiniswa komphezulu ophuculweyo, kuyenza ibe yinxalenye ebalulekileyo yetekhnoloji yekhonkrithi yale mihla.
Ngamafutshane, ukusetyenziswa okutsha kwezongezo zekhonkrithi, kubandakanya uthuthu lwempukane, i-cenospheres, i-perlite eyandisiweyo, iimicrospheres zeglasi engenanto, iintsinga zekhonkrithi, kunye neearhente zokunciphisa amanzi, ziguqula iindlela zokwakha zekhonkrithi. Ezi zongezo aziphuculi nje kuphela iipropati zomxube wekhonkrithi kodwa zikwanegalelo kwizenzo zokwakha ezizinzileyo nezonga amandla. Njengoko ishishini lokwakha liqhubela phambili, ukudityaniswa kwezi zongezo zintsha kuya kuqhubeka ukudlala indima ebalulekileyo ekubumbeni ikamva lobuchwephesha obubambekayo, ukuququzelela uphuhliso lwezakhiwo ezihlala ixesha elide, ezikwaziyo ukumelana nendalo, kunye nezokusingqongileyo.
