Cement Industry in India
The origins of Indian cement industry can be traced back to 1914 when the first unit was setup at Porbandar with a capacity of 1000 tonnes. Today cement industry comprises of 125 large cement plants and more than 300 mini cement plants. The Cement Corporation of India, which is a Central Public Sector Undertaking, has 10 units.
adverse effects slag cement
If the slag cement particles are finer than the Portland cement particles, the rate of bleeding will decrease, and in contrast, if the slag cement particles are coarser than the Portland cement particles, bleeding will increase when substituted on an equalmass basis. The setting time of concrete containing slag cement is commonly retarded.
