Either way, let me know by leaving a comment below. There are a number of uses for cement, and since each use is unique, it needs a different type of cement. One of the most important benefits is the faster rate of development of strength. It produces relatively less solid concrete than PPC, so pumping the concrete becomes a bit difficult. Therefore it is necessary for the cement industry to produce clinker that would facilitate the production of low w/c concrete that are more durable than general strength concrete. Cement with lower alkali content has caused objectionable expansion. Sand from the banks of Aaji River near Rajkot was used as fine aggregate. OPC stands for Ordinary Portland Cement. This is the most ordinary and common cement used all through the globe. These classifications were totally based on the compressive strength which was achieved after 28 days. OPC has great resistance to cracking and shrinkage. Ordinary Portland Cement. After 1987 higher grade cement were introduced in India. Portland cement is used either in the form of cement mortar or cement … The word Portland is used because the inventor of this cement “Joseph Aspdin” of England in 1824, used the very first cement for the first time to set the stone namely “Portland”.
