Siminti
Ƙididdige yawan siminti da ake buƙata yana da muhimmanci ga kowane aikin gini. Ƙarancin ya tsaya da aikin; yawan ya ɓata kuɗi. Ana ƙididdige girman a kan ƙa'ida mai sauƙi: ga faifai da tushe, shine tsayi × faɗi × kauri (a cikin mita), kuma ga ginshiƙi mai zagaye, shine π × (diameter/2)² × tsayi.
Kalkuletanmu yana goyon bayan tsarin metric (cm/m³) da imperial (ft/in/yd³), kuma ta atomatik yana nuna adadin jakunkunan siminti a girma daban-daban (25 kg, 50 kg, 60 lb, 80 lb).
Nau'o'in Tsari
Faifain siminti — tsari ne mai kwance: benen gareji, falo, saman bene. Kaurin yawanci 10-20 cm ne don gidaje. Don kaya masu nauyi, ana ƙarfafa ta da ƙarfe ko rods.
Ginshiƙi mai zagaye — bangare ne na tsaye mai siffar zagaye: ginshiƙan tallafi, gungumen shinge. Diamita da tsayi suna tantance girman ta amfani da tsarin cylinder. Tushe mai murabba'i — tushe ne a ƙarƙashin bangon gida ko ginshiƙai: girma mai murabba'i tare da kauri mafi girma.

Ready-mix vs site-mixed
Don juzu'i sama da 1 m³, isar da shirye-shiryen gauraya ya fi daidaito kuma yana adana lokaci mai mahimmanci.
Don shingen kankare, ninka tsawon × nisa × kauri (duk a cikin raka'a ɗaya). Misali, shinge mai tsayi 3m × 3m a zurfin 10 cm (0.10 m) = 0.9 m³. Kalkuletan mu yana sarrafa jujjuya raka'a ta atomatik - shigar da girma cikin cm ko ft/inci.
Madaidaicin jaka mai nauyin kilogiram 25 na haɗin kankare yana rufe kusan 0.0104 m³, ma'ana kuna buƙatar kusan jakunkuna 96 a kowace mita cubic. Jaka mai nauyin kilogiram 50 ta rufe kusan 0.0208 m³ (jaka 48/m³). Don ayyuka sama da 2m³, yin odar simintin da aka shirya ta hanyar mota yawanci ya fi dacewa da tattalin arziki.
Rukunin madauwari yana amfani da dabarar silinda: π × (diamita ÷ 2)² × tsawo. Misali, ginshiƙi mai diamita 30 cm (0.3 m) da tsayi 3 m = π × 0.15² × 3 ≈ 0.212 m³.
