"Portland Cement: What We Build With"

Download file to see previous pages It has become part of man’s lives since the ancient civilizations have used mortars and binders to be able to construct different structures including the great pyramids of Egypt. Through time and innovations, different types of cements have been formulated to be able to meet the demands of engineering (Cement History, 2013). And with these innovations, issues have also risen especially in terms of the generation of wastes and the safety of the people involved in the manufacture of cement. This paper talks about Portland cement, its chemical composition, applications and the issues concerning the cement manufacture industry.
History of Cement
The actual time when binders were used in structures cannot be clearly identified, but early civilizations like the Egyptians have used burned lime since 2600 B.C., while the Mesopotamians started to use the same binder in 2000 B.C. In 1000 BC, the Phoenicians were the civilization to make a binder that can set underwater. They were able to make it so by mixing ground volcanic rocks or brick with mortars. The Greeks were also able to make structures of their own in 150 BC by using, emplekton; which is a mixture of stones and mortar (Cement history, 2013).
Romans were the first to actually discover the technology of using cement as binder in making structures. During the early times, Romans mixed Calcium carbonate (CaCO3) or lime with volcanic ash, and from then on was used in the construction of the Colosseum and the Pantheon. However, the technology that was established by the Romans, died with the empire and was rediscovered only in the 1600’s (Wansbrough, n.d.)....

In 1810, an English man named Edgar Dobbs was able to patent a cement which used clay, road dust and lime as its raw materials; but when the patent expired in 1824, Joseph Aspdin grabbed the opportunity to improve on the technology to produce the cement was the person who introduced the cement we currently know as Portland cement. The name of the cement was derived from the Portland stone which is quarried in the island of Portland in England (Van Oss, 2005). Chemistry of Cement The most common type of cement now used all over the world is Portland cement. It is made with mixtures of the oxidized forms of calcium, silicon, aluminum and iron. These materials are subjected to very high temperature reaching ...Download file to see next pagesRead More

We performed hand compaction by tamping it with a tamping rod and packing the constituents tightly in the mould. Compaction by vibration is the most efficient method of compaction and gives best results for low water/cement ratio concrete. Where only a concrete of a desired strength is required, it can be obtained by compaction by vibration of leaner mixes than possible with hand...
