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 beNcam: Ii-aggregates kufuneka zibe nokusabalalisa ubungakanani be-particle ye-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 oluphezulu lwamasuntswana kunye nomxhuzulane okhethekileyo negalelo 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 iiaggregates ezifanelekileyo ezihlangabezana neemfuno ezithile kunye neendlela zokusebenza zokwakha izicelo zodaka.
