Cement Ki Khoj Kisne Ki

Ghar banane ke liye jo sabse important material hai. Vah cement hoti hai. Cement Ke Bina Ghar banana bahut Hai Mushkil Hai. Purane time me ghar banane ke liye Mitti ka istemal Kiya jata tha aur Aaj Bhi Kahi Kahi par Mitti ka istemal Kiya jata hai. lekin lagbhag sabhi jagah cement ka istemal sabse Jyada hota hai Kyunki cement sabse majboot material hai. Ghar banane ke liye cement ka istemal sirf Bricks ko or Concrete ko majbuti dene ke liye Kiya jata hai. Agar cement Ko Pani ke sath Milaya  jaye To Kuch time ke liye upyogi Rahega. Uske baad vah jamkar majbut ho jayega. Or agar aap Concrete or bricks ke sath cement ko laga dete hai. To vah unhe bhi maibut bana deta hai.

Cement ka asali name Portal cement hai. Portal koi brand ya company ka name nahi hai. Yah sirf Portland ki language hai. Ise Portal kaha jata hai.

Cement Ka Itihas 

Cement ka itihas bahut purana hai. Kyonki Ancient civilizations ne building construction ne hi asi  material ka istemal  karte the. lekin 18th century me Britain me ships ke nuksan ko rokne ke liye Rocks ko  Lighthouse banane ki jarurt thi. Us time cement ka istemal ujagar huaa.

Sabse pahle 1824 me Joseph Aspidine ne Portland Cement ” ko patent karwaya unhone ise mitti or chuna stone se banaya ise Concrete se banaya th. Isliye ise Portland cement kaha. Kyonki Portland chuna stone ki tarah dikhata hai. Or 1845 Ashes Johnson  ne Portland cement ko modern istemal ke liye banaya.

Ashes Johnson ne Portland cement banane ke liye isi material ka istemal kiya tha. Jo ab ham istemal karte hai. Aaj to alag alag quality ki cement banai jati hai. Or bahut si company alag alag name se cement ka production karti hai.

 Cement Kaise Banta Hai

Sabse pahle cement ko banane ke liye istemal hone wala Raw material calcium, silicon, iron  or aluminum  khadano se nikalkar Factories tak laya jata hai. Jab Raw material factory ke andar laya jata hai. To vah Pure nahi hota Chuna stone ke andar calcium hota hai. Or  silicon, iron  or aluminum ret ke andar hota hai.

Phi inko saf karke o achi tarah pisa jata hai. Or ek poured Powder tayar kiya jata hai. Aam tor par chuna stone 80% hai. Or baki 20 mitti hoti hai. Phir ise Raw materials ko Machines dwara piskar ek power tayar kiya jata hai. Or isko 1500 Degree Celsius par gram kiya jata hai.

Or phir Calcium or silicon dioxide ke compounds ke bich chemical reaction hoti hai. Tab cement banti hai. Or phir cement ko bahar nikal kar cool kiya jata hai. Or phir dubara usko machine ke andar ek baar phir gram kiya jata hai. Or phir usko bahar nikal kar  cool karke pack kiya jata hai. Yah labbha 20-40 Kg bag tak pack kiya jata hai. Or aapke pass punchai jati hai.

Cement Ke Parkar

Cement koi ek parkar ki nahi hoti hai. Iske andar istemal hone Raw material o quality or capacity ke hisab se bahut si parkar ki hoti hai. Sabhi jagah ek parkar ke cement ka istemal nahi kiya ja sakta hai. kai jagah to achi quality ki or achi capacity wali cement ka istemal karna padta hai. Jaise Bridges ke Construction or badi badi Buildings ke Construction me achi quality ki cement jaruri hoti hai. Lekin kai choti jagah par kam capacity wali cement ka istemal bhi kiya jata hai. Jinki Grade thodi si kam hoti hai. Isliye inke istemal ke aadhar par hi cemen alag alag quality ki banai jati hai.
