Ukubala izinguquko zedensi yomxube wesihlabathi-uphondo-izinsalela kubalulekile emikhiqizweni yokwakha nasezinhlelweni zobunjiniyela. Ukuqonda lezi zinguquko kuqinisekisa ukusetshenziswa kwemathiriyali ngok准确および構造の完全性. Le ncwadi inikeza umhlahlandlela ophelele wokubala izinguquko zedensi zalemixube, ezivezwa ngama-tonne/m³.
Ubuningi buchazwa njenge masi ngeyunithi yevolumu yesifaniso. Emkhakheni wezingxube zeshayina-ukwakha-izihlabathi, ubuningi busiza ekunqumeni ukuthi malini impahla edingekayo ukuze kutholakale ivolumu ethile. Ifomula yebuningi iyinhloko:
\[ \text{Ubuningi} = \frac{\text{Ubuwelwe}}{\text{Ivolumu}} \]
Ngaphambi kokubala ukuguqulwa kwedensity, kubalulekile ukuqonda izingxenye ezithintekayo:
Ukuze ubale ukujikeleza kokuhlwithwa kwe-sand-cement-gravel, landela lezi zinyathelo:
Ithrekhi ngalinye linenqwaba ethile, ivamise ukuboniswa nge-kg/m³. Nansi imibandela ethile yokuphakelayo yeziqalo ezivamile:
Bala isisindo esiphelele sokuhlanganiswa usebenzisa izilinganiso zezigaba nganye. Thatha isilinganiso sokuhlanganiswa esingu-1:2:3 (ukwakha:ushayayo:ugwava) njengokukhombisa:
Guqula ubunzima ukusuka kumakilogramu ubuye kumatonnes (1 tonne = 1000 kg):
Sebenzisa ubudlelwane bokuxuba ukuze ubale ubukhulu bokuxuba okubumbene:
\[ \text{Ubuningi Obuhlangene} = \frac{1 \times 1.44 + 2 \times 1.60 + 3 \times 1.80}{1 + 2 + 3} \]
\[ \text{Ububanzi Obuhlukahlukene} = \frac{1.44 + 3.20 + 5.40}{6} \]
\[ \text{Ubuningi Obuhlukahlukene} = \frac{10.04}{6} \]
\[ \text{Ubukhulu Obuhlukahlukene} \approx 1.67 \, \text{ithoni/m}^3 \]
lapho ubala ukudluliselwa kwezindawo, cabangela okulandelayo:
Ukubala uguquko lwezilinganiso zokuhlala kwensimbi-nkanyezi-igobho kubandakanya ukuqonda izindawo zomkhiqizo, ukuguqula umthamo ube zontanga, nokusebenzisa izinga lokuhlanganisa ukuthola isisindo esiphelele. Ukuqinisekiswa kokusebenza kahle kuqinisekisa ukusetshenziswa okuphumelelayo kwemateriali futhi kube negalelo empumelelweni yemisebenzi yokwakha. Naka njalo izinto ezisebenzayo ezinjengokuqukethwe kokubili okukhuhla kanye nokuqiniswa lapho wenza lezi zibalo.
