Zeziphi izinto ekufuneka ziqwalaselwe ekukhethweni kwee-aggregates ezisetyenziselwa ukwakha udaka?

Ukukhethwa kweeaggregates zokwakhiwa kodaka kubalulekile njengoko kuchaphazela ngokuthe ngqo iipropati kunye nokusebenza kodaka. Zininzi izinto ekufuneka ziqwalaselwe xa ukhetha aggregates:

1. Ukuhanjiswa kobungakanani beNgxelo: Ii-aggregates kufuneka zibe nokusabalalisa ubungakanani be-particle ukuze kuqinisekiswe ukupakishwa okufanelekileyo kunye nokunciphisa i-voids kumxube wodaka. Ukusabalalisa okulinganayo kwamaqhekeza, ama-fine, kunye namaqhekeza okuzalisa kunceda ukuphucula ukusebenza kunye namandla.
2. I-Particle Shape: Imilo yee-aggregates ichaphazela ukusebenza, ukuhambelana, kunye namandla odaka. I-angular okanye i-rough-surface aggregates ibonelela ngokunxibelelana okungcono koomatshini kunye nokuphucula amandla ebhondi xa kuthelekiswa ne-aggregates engqukuva okanye egudileyo.
3. Ubume boMphezulu: Ubume bomphezulu be-aggregates buchaphazela ibhondi phakathi kwamasuntswana adibeneyo kunye ne-matrix yodaka. Ii-aggregates ezinokwakheka komphezulu orhabaxa zinika ukomelela kwebhondi eyongeziweyo kunye nokuncamathela xa kuthelekiswa neeaggregates ezigudileyo.
4. Ukufunxa kunye noMqulatho wokufuma: Ii-aggregates kufuneka zibe ne-absorption ephantsi ukukhusela ukugqithiswa kwamanzi okugqithisileyo kumxube wodaka, oku kunokukhokelela ekunciphiseni ukusebenza kunye namandla. Ubuninzi bomswakama obuninzi kwii-aggregates kunokubangela utshintsho lwevolumu kunye nokuchaphazela ukusebenza kodaka.
5. Uxinaniso lweNtsukwana kunye noMxhuzulane oKhethekileyo: Iiaggregates ezinoxinano lwamasuntswana aphezulu kunye nomxhuzulane okhethekileyo zinegalelo kwimixube exineneyo neyomeleleyo yodaka. I-aggregates ekhanyayo ingasetyenziselwa ukunciphisa ubunzima bomdaka kunye nokuphucula iimpawu ze-thermal insulation.
6. Ukucoceka nokungcoliseka: Ii-aggregates kufuneka zingabinazinto eziphilayo, udongwe, intlenga, uthuli, kunye nezinye izinto ezingcolisayo ezinokuchaphazela kakubi iimpawu zodaka. Ii-aggregates ezingcolisekileyo zinokukhokelela kumandla angekho mgangathweni webhondi, imiba yokuqina, kunye nokungcoliswa komphezulu.
7. Ukuqina: Ukuqina kwee-aggregates kubalulekile ukuqinisekisa ukusebenza kwexesha elide lodaka. Ii-aggregates kufuneka zixhathise imozulu, uhlaselo lwekhemikhali, kunye nemijikelo yokunyibilika komkhenkce ukugcina ingqibelelo yodaka ngokuhamba kwexesha.
8. Ubukho neendleko: Qwalasela ukufumaneka kunye neendleko zeeaggregates, ingakumbi kwiiprojekthi ezinkulu zokwakha. Iaggregates ezifunyenwe ekuhlaleni zihlala zikhethwa ukunciphisa iindleko zothutho kunye neempembelelo zokusingqongileyo.

Ngokuqwalasela le miba, abakhi kunye neenjineli banokukhetha ii-aggregates ezifanelekileyo ezihlangabezana neemfuno ezithile kunye neendlela zokusebenza zokwakha izicelo zodaka.
