Calculate
Aap ghar ki tameer kar rahe hain aur soch rahe hain ke deewar mein kitni eent, cement aur rait lagegi? Eent ka calculator tab kaam ka hota hai jab paimaish aur settings aap ke project ke mutabiq hon. Is guide mein brickwork ki quantity CFT mein nikalna, mortar ka hisaab aur khareedari ka allowance asaan Roman Urdu mein samjhaya gaya hai.
Eent aur masalay ke liye kaunsa tool use karein?
Hamare Brickwork and Mortar section mein 9 inch deewar ka calculator, 4.5 inch deewar ka calculator aur bunyaad ki eenton ka calculator hain. In mein volume CFT ya m³ mein daalein. Calculator ke controls English mein hain; yeh article unhein Roman Urdu mein samjhata hai.
Yeh tools material ka andaza dete hain. Yeh nahi batate ke deewar ki motai ya bunyaad ka size structurally safe hai. Ghar ke covered area se eenton ka andaza nikalne wala tool alag planning method hai. Aik hi kaam ke liye dono results jama na karein, warna double counting ho sakti hai.
Sab se pehle deewar ki net quantity nikalein
Seedhi deewar ka volume = lambai × unchai × motai. Motai mein plaster aur finishing shamil na karein. Agar lambai aur unchai feet mein hain, to inch ko feet banayein: 9 inch = 0.75 feet aur 4.5 inch = 0.375 feet.
Misal: deewar 20 feet lambi, 10 feet unchi aur 9 inch moti hai. Gross quantity 150 CFT hogi. Isi motai mein 3 × 7 feet ke darwazay ki jagah 15.75 CFT hogi. Net brickwork 134.25 CFT, yani taqreeban 3.802 m³ hai. Mutaliqa darwazay aur khirkiyan minus karein. Corners aur deewaron ke milnay ki jagah do baar na ginein.
Isi lambai, unchai aur darwazay ke saath 4.5 inch deewar ki net quantity 67.125 CFT hogi. Samnay ka area barabar honay se dono deewaron ka volume barabar nahi hota.
Square feet aur CFT mein kya farq hai?
Square feet area hota hai aur CFT volume. 100 square feet deewar lazmi nahi ke 100 CFT bhi ho. Area ko feet mein motai se multiply karein. Metric hisaab mein lambai, unchai aur motai teeno metres mein rakhein to jawab m³ aayega. Aik CFT = 0.028316846592 m³ hai. Tool pehle volume convert karta hai, phir material method lagata hai.
Eent, cement aur rait ka formula
9 inch tool ki starting settings mein 13.5 eent/CFT, mortar fraction 25%, dry-volume factor 1.3 aur cement:rait ratio 1:4 hai. Yeh editable estimating assumptions hain, har site ka lazmi rule nahi. Apni eent ka size, joints aur drawing ki specification zaroor check karein.
D = V × 0.25 × 1.3
Cement bags = D × C ÷ (C + S) ÷ 1.25
Sand CFT = D × S ÷ (C + S)
V masonry ka volume, D dry masalay ka volume aur C aur S cement aur rait ke volume parts hain. Starting assumption mein cement bag 50 kg aur us ka volume 1.25 CFT hai. Bag ya conversion mukhtalif ho to settings badlein. Sirf 1:4 ratio likh denay se mortar ki strength ya engineering suitability tay nahi hoti.
100 CFT brickwork ki worked example
Dry masala = 100 × 0.25 × 1.3 = 32.5 CFT. Cement = 32.5 ÷ 5 ÷ 1.25 = 5.2 bags. Rait = 26 CFT aur eentain = 1,350.
| Material | Base quantity | Chuna hua allowance | Allowance ke saath |
|---|---|---|---|
| Eentain | 1,350 | 5% | 1,417.5 → khareedari ke liye 1,418 poori eentain |
| Cement | 5.2 bags | 5% | 5.46 → 6 pooray bags |
| Rait | 26 CFT | 25% | 32.5 CFT |
Yeh allowances example ki settings hain, har project ke liye recommendation nahi. Toot-phoot, cutting aur transport ko dekh kar har material ka alag allowance rakhein. Pehle allowance lagayein, phir poori eent ya bag ki khareedari ke liye quantity ko upar round karein. Method compare karte waqt unrounded quantity bhi dekhein.
4.5 inch aur bunyaad ka result alag kyun hota hai?
4.5 inch tool ki starting settings mein mortar 30%, dry factor 1.42 aur ratio 1:4 hai. Foundation tool mein yeh 25%, 1.3 aur 1:6 hain. Teeno 13.5 eent/CFT se start karte hain. Is liye barabar input volume par eentain barabar, lekin cement aur rait alag aa sakte hain. Sirf tool ka naam nahi, us ki settings bhi dekhein.
Bunyaad ka volume aur order se pehle checklist
Stepped foundation mein eent ki har layer ki lambai × chorai × unchai alag nikal kar jama karein. Excavation, PCC aur RCC ko brickwork mein shamil na karein. Bunyaad ka size aur bearing requirements approved drawing se lein; calculator foundation design nahi karta.
- Latest drawing aur asal masonry thickness se paimaish karein.
- Openings minus karein aur shared corners check karein.
- Eent ka size aur per-CFT factor confirm karein.
- Mortar, dry factor, ratio aur bag settings dekhein.
- Har material ka allowance alag soch kar rakhein.
- Manual takeoff aur supplier ki packing ke saath result milayein.
Aksar poochay janay walay sawal
Aik CFT mein kitni eentain lagti hain?
Tool ki initial value 13.5 hai, lekin aap isay badal sakte hain. Eent ka size, joints aur bond asal quantity badal dete hain. Isay har jagah ka fixed rule na samjhein.
Kya sirf deewar ka square feet enter kar sakte hain?
In teen tools mein volume chahiye. Pehle area ko matching units mein motai se multiply kar ke CFT ya m³ nikalein.
Kya 4.5 inch deewar hamesha non-load-bearing hoti hai?
Calculator yeh faisla nahi karta. Engineer ki drawing aur local requirements follow karein.
Kya labour, lintel aur plaster shamil hain?
Nahi. In ki quantities aur rates alag nikalne honge.
Ab eenton ki quantity calculate karein, ya bunyaad ka material nikalein. Finishing ke liye plaster cement aur rait calculator use karein.
Method owner ki di hui material workbook aur tool settings par mabni hai. Brick Industry Association ke technical notes fired-clay brick ke baray mein mazeed maloomat dete hain; woh aap ki site ke liye in factors ki tasdeeq nahi hain.
