Ibetoni
Ukubala inani lebetoni elidingekayo kubalulekile kuwo wonke umsebenzi wokwakha. Okuncane kakhulu kuqeda umsebenzi; okuningi kakhulu kuwulahleko wezimali. Umthamo ubalwa ngomgomo olula: kuma-slabs nezinyawo, uwude × ububanzi × ubuzima (ngamamitha), futhi wekholomu eyiyingi, ngu-π × (ubukhulu/2)² × ubude.
Isibali sethu sisekelela izinhelo zombili ze-metric (cm/m³) ne-imperial (ft/in/yd³), futhi sibonisa ngokuzenzakalela inani lamasaka ebetoni ngazohlobo (25 kg, 50 kg, 60 lb, 80 lb).
Izinhlobo Zezakhiwo
I-slab lebetoni — inhlangano ehlanzekile: izitezi zamagalaji, izithende, izindawo zezitezi. Ubuzima buhlala obu-10–20 cm ekusetshenziswa ekhaya. Ngomthwalo omkhulu, kufakwa inethiwekhi yensimbi noma izinduku.
Ikholomu eyiyingi — inhlangano eya phezulu enendawo eyiyingi: izinsika ezixhasayo, izinsika zothango. Ubukhulu nobude kwenza umthamo kusetshenziswa ifomula yesilinda. I-footing yesikwele — umsuka ngaphansi kwezindonga noma izinsika: umthamo wamastharaisi nomkhulu wobuzima.
Amasaka Ebetoni
Ngamaphrojekthi amancane, ukuthenga amasaka ebetoni axunyiwe kunzuzo ngaphezu kokuhla ithrakhi. Isaka lama-25 kg likhuluma mayelana no-0,0104 m³, futhi isaka lama-50 kg likhuluma mayelana no-0,0208 m³. Nohlobo lwase-US, isaka lama-60 lb likhiqiza mayelana no-0,45 cubic feet (0,01274 m³), futhi isaka lama-80 lb likhiqiza mayelana no-0,60 cu ft (0,01699 m³).
Ngamaphrojekthi angaphezu kuka-2–3 m³, ukuhla ibetoni elixunyiwe ngenthrakhi kunenzuzo ngokwezimali. Hlala uhla ngebhafu elingu-10% yezilahleko zokuxuba nokugcina.
Amathiphu
Engeza ibhafa engu-10%.
Ngaso sonke isikhathi oda ngo-5–10% ngaphezu kwalokho kubalwe ukuze kuhlangatshezwane nokulahlekelwa kanye nokungahambi kahle kwendawo.
Ibanga likakhonkolo
Ukuze uthole izisekelo nama-slabs, sebenzisa okungenani ikilasi C20/25. Ngezindlela zokushayela namagaraji, sebenzisa i-C25/30 noma ngaphezulu.
Izinga lokushisa libalulekile
Ungathululi ukhonkolo ngaphansi kuka-5°C noma ngaphezu kuka-35°C ngaphandle kwezinyathelo ezikhethekile — ngeke zelaphe ngendlela efanele.
Ukuqiniswa
Kuma-slabs ububanzi kuno-2 m kanye nezakhiwo ezithwala umthwalo, qinisa njalo nge-mesh yensimbi noma i-rebar.
Isikhathi sokuphumula
Ukhonkolo ufinyelela amandla angu-70% ezinsukwini ezingu-7 namandla aphelele ezinsukwini ezingu-28. Kugcine kumanzi ngalesi sikhathi.
I-Ready-mix vs i-site-mix
Kuvolumu engaphezu kuka-1 m³, ukulethwa kwengxube elungile kufana kakhulu futhi konga isikhathi esibalulekile.
Ukuze uthole i-slab kakhonkolo, phindaphinda ubude × ububanzi × ukujiya (konke kuyunithi efanayo). Isibonelo, i-slab engu-3m × 3m ekujuleni okungu-10 cm (0.10 m) = 0.9 m³. Isibali sethu siphatha ukuguqulwa kweyunithi ngokuzenzakalelayo — faka ubukhulu ngo-cm noma ft/intshi.
Isikhwama esijwayelekile esingu-25 kg sengxube kakhonkolo simboza cishe u-0.0104 m³, okusho ukuthi udinga izikhwama ezingaba ngu-96 cubic meter ngayinye. Isikhwama esingu-50 kg sivala cishe u-0.0208 m³ (48 izikhwama/m³). Kumaphrojekthi angaphezu kuka-2 m³, uku-oda ukhonkolo osulungile ngeloli kuvamise ukonga kakhulu.
Ikholomu eyindilinga isebenzisa ifomula yesilinda: π × (ububanzi ÷ 2)² × ubude. Isibonelo, ikholomu enobubanzi obungu-30 cm (0.3 m) nobude obungu-3 m = π × 0.15² × 3 ≈ 0.212 m³.
Yebo - kuyatuswa ukuthi wengeze u-5-10% ukuze ubalekele ukuchitheka, izindawo ezingalingani, kanye nokulahlekelwa okuxutshwayo. Uma indawo ye-slab inemiphetho engajwayelekile noma umhlabathi ungekho ezingeni eliphelele, engeza u-10% ukuze uphephe.
I-slab iyindawo evundlile (phansi, i-patio, i-driveway), ngokuvamile i-10-20 cm ubukhulu. I-footing iyisici sesisekelo sesakhiwo esibekwe ngaphansi kwezindonga noma amakholomu, ngokuvamile ashubile (20-60 cm) futhi abe mncane, eklanyelwe ukudlulisa imithwalo emhlabathini.
