Yiziphi izici okufanele zibhekwe lapho kukhethwa ama-aggregate asetshenziselwa ukwakha udaka?

Ukukhethwa kwe-aggregate yokwakha udaka kuncike ezintweni eziningana, okuhlanganisa:

1. Ukusatshalaliswa kosayizi wezinhlayiya: Usayizi wezinhlayiyana zamaqoqo uthinta ukusebenza, amandla, kanye nokuqineka kodaka. Ama-aggregates anezinhlobonhlobo zamasayizi wezinhlayiyana angathuthukisa ukuminyana kokupakisha futhi anciphise ukugcwala kodaka, okuholela ekuthuthukisweni kwamandla nokuqina.
2. Umumo nokuthungwa: Ukuma nokuthungwa kwenhlanganisela kuthinta isibopho phakathi kodaka ne-substrate. Ama-aggregate anezindawo ezingama-angular noma ezimaholoholo anganikeza ukuhlobana nokunamathela okungcono, kuyilapho ukuhlanganisa okubushelelezi noma okuyindilinga kungase kubangele ukuhlangana okubuthakathaka.
3. Ukuminyana: Ukuminyana kwama-aggregates kuthinta isisindo kanye nevolumu yodaka. Ama-aggregate alula anganciphisa isisindo sonke sesakhiwo, kuyilapho ama-high-density aggregate angakhuphula amandla nokuqina kodaka.
4. I-Porosity: I-porosity yama-aggregates ithinta isilinganiso samanzi-simende kanye nokuncipha kokuqina kodaka. Ama-aggregate ane-porosity ephansi anganciphisa isidingo samanzi kanye nokuncipha kokuqina, okuholela ekuqineni okuthuthukisiwe kanye nokuncipha kokuqhekeka.
5. Ukwakheka kwamakhemikhali: Ukwakheka kwamakhemikhali kwezinhlanganisela kungase kuthinte isikhathi sokusetha, amandla, nokuqina kodaka. Ama-aggregate anamazinga aphezulu ezinto eziphilayo noma ama-sulfate angaphazamisa inqubo yokufaka usimende futhi kuholele ekunciphiseni kwamandla nokuqina.
6. Ukutholakala nezindleko: Ukutholakala nezindleko zamaqoqo zingahluka kuye ngendawo nesidingo. Ukutholakala kwendawo kwama-aggregate kunganciphisa izindleko zokuhamba kanye nemithelela yemvelo, kuyilapho izilinganiso zekhwalithi ephezulu zingase zinyuse izindleko zodaka.
