"Material achha lagega" — har thekedaar yahi kehta hai. Par achha matlab kya? Is guide mein hum batayenge ki site pe aaye cement, sariya, eent aur tiles ko aap khud kaise parakh sakte hain — bina engineer bane.
Cement: bag pe ye 5 cheezein dekhiye
- ISI mark aur licence number (CM/L) bag pe chhapa ho.
- Type aur grade — jaise OPC 43, OPC 53 ya PPC — saaf likha ho.
- Manufacturing date (ya week) — cement jitna taaza, utna behtar. Purana cement nami pakad kar kamzor ho jaata hai.
- Bag ki silaai sahi ho, kata-phata ya dobara sila hua na ho. Bag ka wazan (aam taur pe 50 kg) pe shak ho to taul kar dekhiye.
- Haath daal ke dekhiye — cement thanda aur mulaayam lage, usme gaanthein (lumps) na hon.
Sariya (TMT bar): grade, nishaan aur wazan
Achhe brand ke TMT sariye pe thodi-thodi doori pe brand ka naam aur grade (jaise Fe 500, Fe 500D, Fe 550) ubhra hua hota hai. Saath mein ISI mark aur supplier se test / mill certificate maangiye.
Sariya kam motai ka to nahi — yeh check karne ka aasaan tareeka hai wazan. Sariye ka standard wazan formula se nikalta hai: wazan (kg/meter) = d² ÷ 162 (d = mm mein motai).
| Sariya (mm) | Lagbhag wazan (kg/meter) | 12 meter ki ek chhad |
|---|---|---|
| 8 mm | 0.395 | ~4.7 kg |
| 10 mm | 0.617 | ~7.4 kg |
| 12 mm | 0.888 | ~10.7 kg |
| 16 mm | 1.58 | ~19 kg |
| 20 mm | 2.47 | ~29.6 kg |
Halki si bhoori parat aam hai, par papdi jaisi utarti jung wala sariya mat lijiye.
Eent (bricks): teen aasaan test
- Rang aur shape: ek jaisa laal rang, seedhe aur tez kinaare, koi daraar nahi.
- Awaaz: do eentein aapas mein takraaiye — achhi eent se saaf "khanak" aati hai, kachchi eent se dhap-si awaaz.
- Nakhun test: nakhun se khurachne pe achhi eent pe nishaan nahi padta.
Tiles aur marble
- Dibbe pe grade, size aur shade / batch number dekhiye. Ek kamre ki saari tiles ek hi batch ki hon.
- Do tiles ko muh se muh mila kar dekhiye — beech mein gap ho to tile tedhi (warped) hai.
- Kinaare aur kone tute na hon; glaze pe bubbles ya daag na hon.
- Bathroom aur bahar ke liye anti-skid tiles chuniye.
Bijli ke taar aur plumbing
- Taar pe ISI mark, brand aur size (sq. mm) chhapa ho; ghar ke liye FR / FRLS taar behtar maane jaate hain.
- Pipe aur fittings pe ISI mark aur class likhi ho.
- Switches aur MCB branded hon — yeh suraksha ka sawaal hai.
Site pe material ka hisaab: stock register
Sabse aasaan aur sabse kaam ka tareeka — site pe ek register rakhiye. Har din likhiye: kitne cement bag aaye, kitne lage, kitna sariya aaya aur kitna bacha.
- Truck aane pe bill se maatra mila lijiye — bag gin kar, sariye ki chhadein gin kar.
- Hafte mein ek baar bacha hua stock gin lijiye; achanak "kam pad gaya" wali baat pakdi jaati hai.
- Bachi hui tiles aur paint ke dibbe rakh lijiye — baad mein marammat ke kaam aate hain.
Sabse zaroori: pakka bill
Har material ka GST wala pakka bill lijiye jisme brand, grade aur maatra likhi ho. Bill hi saboot hai ki jo maanga, wahi aaya.
Aksar pooche jaane wale sawaal
OPC 43 aur OPC 53 cement mein kya fark hai?
Number 28 din baad cement ki compressive strength batata hai — 43 aur 53 N/mm². OPC 53 jaldi aur zyada majbooti deta hai, isliye aksar RCC kaam mein lagta hai; plaster aur chinaai ke liye 43 grade ya PPC bhi aam hai. Engineer ki salaah se chuniye.
PPC cement kya hota hai?
PPC (Portland Pozzolana Cement) mein fly ash jaisa pozzolana mila hota hai. Yeh dheere-dheere majbooti pakadta hai aur plaster, chinaai jaise kaam mein khoob istemaal hota hai.
Fe 500 aur Fe 500D sariye mein kya fark hai?
500 ka matlab hai sariye ki yield strength 500 N/mm². "D" wala sariya zyada ductile (lachila) hota hai — tootne se pehle zyada khinch sakta hai, jo bhookamp jaise jhatkon mein behtar maana jaata hai.
