Building materials cement

The presentation is descriptive about the basics of cement and cement industry in india and abroad. this was our project in 1st year of B.arch from school of planning and architecture, bhopal, india.

1. Presentation by : Karan, D evashree , Ashi , Ajay, Nikunj CEMENT

2. The word cement has come from the roman word ‘OPUS CAEMENTICIUM  An adhesive substance of all kinds, but, in a narrower sense, the binding materials used in building and civil engineering construction. What Is CEMENT?

3. History of Cement

4. Physical Strength to masonry Excellent binding material Easily workable Stiffens early Possesses good plasticity Offers good resistance to the moisture Fineness: Soundness Alumia : Iron oxide ≥ 0.66 0.66≤Lime saturation factor ≤1.02 Sulphur content ≤ 2.75 % Wt. of insoluble residue ≤ 1.5% Properties of cement Chemical

5. COMPOSITION It is quite important to maintain the composition of cement because all the functions of every type of cement depends on individual quantity of every component.

6. FUNCTIONS OF CEMENT INGREDIENTS

10. Manufacturing of cement

11. CEMENT Production Regulates set and clinker + gypsum=cement

12. S etting and harderning of cement Setting-  is used to describe the stiffening of the cement paste. It refers to changes of cement paste from a fluid to rigid state. Setting differs from Hardening of cement. Hardening –it refers to the gain of strength of a set cement paste, although during setting the cement paste acquires some strength. Initial setting time indicates the beginning of the setting process when the cement paste starts losing its plasticity. Final setting time is the time elapsed between the moment water is added to the cement and the time when the cement completely lost its plasticity and can resist certain definite pressure. It includes two processes initial set and final set stages

13. SITE FOR CEMENT FACTORY

14. INDIAN CEMENT INDUSTRY The Indian cement industry is the 2nd largest market after China accounting for about 8% of the total global production. Housing sector is the biggest demand driver of cement(67%) followed by  infrastructure (13%), commercial construction (11%) and industrial construction (9%).

15.  Andhra Pradesh is the largest producer of cement in India followed by Rajasthan and Tamil Nadu . SATNA, cement city, in MP, is in the limestone belts of India. As a result, it contributes around 8%–9% of India's total cement production. India is producing different varieties of cement like ordinary Portland cement, Oil well cement, sulphate resisting cement, white cement etc. Production of these verities conform to BIS standards.

16. FUTURE ALTERNATIVES TO CEMENT Quantity of trash is Increasing in this world day by day which has ignited the architects to find new ideas such as : Alok shetty’s concept of recycling tin cans, plastic bottles, etc and laying them with very less quantity of cement. GREEN CEMENT REASEARCH by Peter Trimble who proposed a bacterium based design combined with sand producing 70% much stronger cement.

17. FIELD TESTS and MARKET SURVEY
