“Concrete strong hone ke baad bhi crack kyu ho jata hai? 🤔
"Cement ka sabse basic test… par sabse important 😳
Ignore kiya toh pura mix design bigad jayega!"
अंदाज़ से nahi… IS 4031 (Part 4) se decide hota hai cement ka paani 💧
"⚠️ Cement fine nahi hai to strength bhool jao!
Sirf 1 test se pata chal jata hai pura quality 👇
Fineness test ignore = future crack guarantee 😳
Slump sahi nahi = Concrete weak
Water badhaya = Strength gayi Smart engineer admixture use karta hai
👉 “Jitna jyada paani… utni kam strength 🤯
Ye sach bahut log ignore kar dete hai
“Cement ke bag par likha 33, 43, 53…
👉 Tumhe lagta hai price hai? ❌
Sach suno 👇
👉 Ye hoti hai 28 din ki strength 💪
Ab batao… tumne kabhi notice kiya tha? 🤯
👉 Follow karo aur aise hi real site knowledge lo
“Cement ka bag sabko same lagta hai… lekin sach alag hai 😮
👉 Ordinary Portland Cement (OPC) 3 grades me aata hai:
✔ 33 Grade – Normal construction
✔ 43 Grade – RCC work
✔ 53 Grade – High strength concrete
⚠ Galat grade choose kiya to structure ki strength affect ho sakti hai!
📌 Save karo aur future me use karo 👇
