आख़िर opc 53 ग्रेड cement बंद क्यों हुआ | opc 53 grade cement | opc vs ppc
jab bhi hamare man me ghar banane ka vichar aata hai, tab sabse pahle hum cement konsi lagana hai yah vichar karte hai iske bad baki material ke bare me vichar kiya jata hai, lekin kya apne kabhi socha hai ki agar hum koi bhi cement apne ghar me lagate hai to uska hamre ghar ki majbuti me kya prabhav padega,
apne pahle ke kam me dekha hoga jyaatar log 53 grade ki cement ghar me lagane ke bare me jyada vichar kiya karte the , kintu aaj ke dor me apko 53 grade ki cement dekhne ko nahi milegi eisa kyu hai or agr hum iski jagah dusri cement lagate hai to iska ghar ki majbuti me kya asar hoga,
ghar me dusri cement lagane se mera matalab kisi comapny ki cement ke bare me bat karne ka nahi hai jaise ki ultratech cement ambuja cement acc cement perfect cement jk super our jk laxmi cement aadi mera matlab hai type of cement ke bare me batane ka jaise ki-
1. Ordinary Portland cement (OPC)
2. Portland pozzolana cement (PPC)
3. Rapid-hardening cement
4. Extra-rapid-hardening cement
5. Quick-setting cement
6. Low-heat cement
7. Sulfate-resisting cement
8. Blast furnace slag cement
9. High-alumina cement
10. White cement etc.
isme me sabhi cement ki bat nahi karunga mai apko sirf opc cement vs ppc ke bare me bataunga ki aaj ke samay me opc 53 grade cement band kyu hua or uski jagah ppc cement ne kyu le liya.
chaliye bat karte hai apne tipc par ki cement me kya kya mila hota hai
1. Lime
2. Silica
3. Alumina
4. Calcium sulphate
5. Iron oxide
6. Magnesia
7. Sulphur Trioxide
ab ye bhi janna jaruri hai ki opc cement or ppc cement me kya mila hota hai jab aap sahi tarike se meri bat ko samajh payenge
dono cement opc ( Ordinary Portland cement ) or ppc ( Portland pozzolana cement ) ke basic composition ki bat kare to-
OPC is produced with 95 % clinker and 5 % gypsum. PPC is produced by 70 % clinker, 20 % fly ash, and 5 % gypsum.
govt aaj ke time me ppc cement jyada use karne ko bol rahe hai wo is karna ki isme fly ash ki matra jyada use hoti hai jo ki environment ke liye bahut jyada achha hai or rahi bat strength ki to wo bhi isme opc 53 grade ke barabar hi milti hai agr aap 28 din me test karte hai to or dusra fayada ppc cement me ye bhi hai ki isme cracks devlope nahi hote hai jisse ghar me crck aane ki sambhavna bahut kam ho jati hai.
itna sab kuch samjhne ke bad apko clear ho gaya hoga ki hum ppc kyu use karte hai dosto aaj ke liye itna hi milte hai next video me tab tak ke liye thank you.
