6. For all structural elements, M25 grade concrete will be used. However, higher M30 grade concrete is used for central columns up to plinth, in ground floor and in the first floor. 7. Sizes of all columns in upper floors are kept the same; however, for columns up to plinth, sizes are increased. 8. The floor diaphragms are assumed to be rigid. 9.

The first Gearless Mill Drive (GMD) with a power of 6.5 MW was installed 1969 in a cement milling process in the cement plant Le Havre in France. In the first few years, the GMD was only used in the cement industry. The GMD is also known as "wrap-around motor" or

Concrete • The world's most widely used building material. • Global production is 5 billion cubic yards per year (using approximately 1.25 billion tons of cement). 7. Concrete owes its strength and durability to one essential ingredient - Portland Cement. 8. Portland Cement • Limestone + Shale/Clay + Heat = Clinker + CKD + Exit Gas.
