Yiziphi izinto ezidinga ukubhekwa ekukhetheni ama-agregates asetshenziselwa ukwakha udaka?

Ukukhethwa kwama-agregates wokwakha udaka kubalulekile njengoba kuthonya ngqo izakhiwo kanye nokwenza udaka. Kudingeka kubhekwe izinto eziningana lapho ukhetha ama-aggregates:

1. Ukusatshalaliswa kosayizi wezinhlayiyana: ama-aggregates kufanele abe nosayizi ohlelwe kahle wezinhlathihla ukuqinisekisa ukupakisha okufanele futhi anciphise ama-voids ku-dutar mix. Izinhlayiya ezilinganiselayo zezinhlayiya ezihlanganayo, ezinhle, nezinhlanzi ezisiza ukuthuthukisa ukukhiqizwa namandla.
2. Ijaji lezinhlayiyana: ukwakheka kwezinhlangothi kuthinta ukusebenziseka, ukuhlangana, namandla odaka. Ama-aggregates angular noma angenalutho avuthiwe ahlinzeka ngokuxhumeka okungcono kwemishini futhi athuthukise amandla e-bond ngokuqhathaniswa nezihlanganisi eziyindilinga noma ezibushelelezi.
3. Ukuthungwa komhlaba: Ukuthungwa komhlaba okuhlanganisiwe kwe-aggregates kuthonya isibopho phakathi kwezinhlayiya ezihlanganisiwe kanye ne-matrix yodaka. Ama-aggregates anomugqa ovuthayo wokuthungwa komhlaba anikela amandla e-bond kanye nokunamathelisa kuqhathaniswa nezinhlanganisela ezibushelelezi.
4. Ukutholwa kanye nokuqukethwe komswakama: ama-aggregates kufanele abe nokutholwa okuphansi ukuvikela ukumuncwa kwamanzi ngokweqile kusuka ku-durtar mix, okungaholela ekusetshenzisweni okuncishisiwe namandla. Okuqukethwe okunomswakama ngokweqile kuma-aggregates nakho kungadala ushintsho lwevolumu futhi kuthinte ukusebenza kodaka.
5. I-Parsicle density kanye namandla adonsela phansi athile: ama-aggregates anokuqina kwezinhlayiyana okuphezulu kanye namandla athile adonsela phansi anikela ngokuxubana kodaka okunamandla. Ama-aggregate angasindi angasetshenziswa ukunciphisa isisindo sodaka futhi athuthukise izakhiwo zokufakelwa okushisayo.
6. Ukuhlanzeka kanye nokungcoliseka: Ama-aggregates kufanele akhululeke ezintweni eziphilayo, ubumba, othulini, uthuli, kanye nokunye okungcolisayo okungathinta kabi izakhiwo zodaka. Ama-aggregate angcolisiwe angaholela emandleni e-bond ampofu, izingqinamba ezitshalekayo, kanye nokuhlaselwa komhlaba.
7. Ukuqina: Ukuqina kwama-aggregates kubalulekile ukuqinisekisa ukusebenza kwesikhathi eside kodaka. Ama-aggregates kufanele amelane nesimo sezulu, ukuhlasela kwamakhemikhali, kanye nemijikelezo eqhwa-iqhwa ukuze kugcinwe ubuqotho bodaka ngokuhamba kwesikhathi.
8. Ukutholakala nezindleko: Cabanga ukutholakala nezindleko zokuhlanganisa, ikakhulukazi amaphrojekthi wokwakha amakhulu. Ama-aggregates asendaweni athambile ajwayele ukuthandwa ukunciphisa izindleko zokuhamba kanye nomthelela wezemvelo.

Ngokubheka lezi zinto, abakhi nonjiniyela bangakhetha ama-aggregates afanele ahlangabezana nezidingo ezithile nezinqubo zokusebenza zokwakha izinhlelo zodumbu.
