Calculate
Concrete aur RCC calculator khareedari se pehle material ka andaza banane mein madad karta hai, lekin sahi hisaab ke liye area, tayyar concrete ke volume aur dry material ke volume ka farq samajhna zaroori hai. Sirf chhat ke square feet se cement ki boriyan nahin nikalti; thickness, units aur mix ki assumptions bhi chahiye. Is guide mein aap aik hal shuda misaal, cement, rait, bajri aur ibtidai sariye ka hisaab dekhein ge. American ACI aur ASTM references ka maqsad bhi samjhaya gaya hai. Maqsad aisa estimate banana hai jo supplier aur engineer ke saath check ho sake, na ke calculator ko structural design ya mazbooti ki guarantee samajhna.

Plain concrete aur RCC mein kya farq hai?
Concrete mein cement par mabni binder, pani aur aggregates shamil hote hain. Pakistan mein PCC aam tor par plain concrete aur RCC sariye wali concrete ke liye bola jata hai. America mein RCC ka matlab roller-compacted concrete bhi ho sakta hai, is liye order par material ka poora naam likhein.
Chhat ki mehfooz thickness, beam size aur sariye ki spacing calculator tay nahin karta. Yeh load, span, exposure aur approved design se aati hain.
Kaunsa concrete tool istemal karein?
- Concrete volume calculator rectangular dimensions aur volume allowance ke liye hai.
- RCC slab material calculator mein measured volume aur badalne wali mix settings dalein.
- Column aur footing tool se har item alag rakhein.
Slab, beam, column aur foundation ka takeoff alag karein. Intersection ka aik hi concrete do martaba count na ho.
CFT, cubic metre aur cubic yard ki misaal
Farz karein length 20 ft, width 15 ft aur drawing ki thickness 6 inch hai. Pehle 6 ÷ 12 = 0.5 ft karein. Phir 20 × 15 × 0.5 = 150 CFT. Yeh sirf arithmetic hai, thickness ki recommendation nahin.
| Quantity | Natija |
|---|---|
| Net volume | 150 CFT |
| Metric | 4.248 m³ |
| US cubic yards | 5.556 yd³ |
| Misaali 5% allowance | 157.5 CFT ya 5.833 yd³ |
Yeh 5% koi lazmi American standard nahin. Pour conditions, uneven surfaces aur supplier ke order rules dekh kar allowance rakhein. Ready-mix ke delivered volume par dry factor na lagayein.
Cement, rait aur bajri ka hisaab
Misaal ke liye 150 CFT, dry factor 1.54, nominal ratio 1:2:4 aur cement bag volume 1.25 CFT rakhein. Dry material 231 CFT aur total parts 7 hon ge.
| Material | Formula | Base quantity |
|---|---|---|
| Cement | 231 ÷ 7 ÷ 1.25 | 26.4 boriyan |
| Rait | 231 × 2 ÷ 7 | 66 CFT |
| Bajri | 231 × 4 ÷ 7 | 132 CFT |
Template ke alag allowances, cement 5%, rait 25% aur bajri 15%, lagane par 27.72 boriyan, 82.5 CFT rait aur 151.8 CFT bajri banti hai. Poori boriyan khareedne ke liye 28 karein. Yeh editable assumptions hain, har site ke lazmi waste rates nahin.
Cement bag aur ready concrete bag alag hain
Template shuru mein 50 kg aur 1.25 CFT per cement bag rakhta hai. Apne product ke mutabiq dono check karein. Jis packaged concrete mein aggregates pehle shamil hon, us ka manufacturer yield istemal karein. Nominal ratio kisi khaas strength ki guarantee nahin.
Sariya: budget estimate, design nahin
Concrete volume se steel calculator editable steel percentage aur density leta hai. 150 CFT, misaali 1% aur 490 lb/CFT se 735 lb bante hain. Exact 2.20462262185 lb/kg par taqreeban 333.4 kg, jab ke template ke purane 2.22 par taqreeban 331.1 kg aate hain.
Koi bhi natija required reinforcement tay nahin karta. Final order approved bar bending schedule, diameters, lengths, laps, anchorage aur bends se banayein.
American ACI aur ASTM references
ACI CODE-318 structural concrete ke liye hai. 2025 edition mojood hai, magar project par applicable edition local adoption aur documents se maloom hota hai. ACI SPEC-301 construction specifications se mutalliq hai.
ASTM C94/C94M, C39/C39M aur C143/C143M ready-mix, cylinder compression testing aur slump test ke references hain. Slump akela strength sabit nahin karta. American document Pakistan ke local requirements ki jagah khud-ba-khud nahin leta.
Cost estimate ko check karne ke qabil banayein
Local dated quotation lein. Concrete, transport, pumping, labour, testing, shuttering, steel aur curing alag rakhein. Site mixing mein har material ka rate, unit aur allowance likhein. Quantity ka tareeqa worldwide chal sakta hai, aik universal rate nahin.
Aam sawalat
Chhat ki concrete kaise nikalein?
Length, width aur thickness aik unit mein multiply karein. Openings aur justified allowance alag rakhein.
Kya calculator PSI batata hai?
Nahin. Volume aur ratio specified strength sabit nahin karte; design aur testing dekhein.
Ready-mix par 1.54 lagana hai?
Nahin. Yeh dry ingredients ka estimating factor hai, delivered concrete ka nahin.
Kya steel percentage drawing ki jagah le sakti hai?
Nahin. Yeh ibtidai budget hai, approved structural design nahin.
Pehle measurement, phir estimate
Concrete volume nikalein ya slab tool kholein. Natijay material estimates hain, mazbooti ya code compliance ka certificate nahin.
