Portland cement, arguably one of mankinds most important manufactured materials, was invented and patented by joseph aspdin from leeds in 1824. aspdin produced cement by heating powdered limestone mixed with clay in a furnace, and grinding the resulting clinker to a powder. he called the product portland cement because of its.
Manufacture of portland cement step 1 – quarrying limestone and a 'cement rock' such as clay or shale are quarried and brought to the cement works. these rocks contain lime (caco3), silica (sio2), alumina (al2o3) and ferrous oxide (fe2o3) the raw materials of cement manufacture. step 2 raw material preparation to form a consistent.
The portland cement is the most basic and the most commonly used cement in the world the portland cement was formerly known as ordinary portland cement and is made by adding gypsum into the clinker. concrete is made by adding the portland cement , water and gravel and sand.
Manufacturing of ordinary portland cement by wet process. slurry : for making cement we take about 65 limestone and 35 calcareous. we collect limestone from stone quarry. limestone is crushing by jaw crusher into smaller pieces. size of these crushing limestone may be 20 to 25 millimeter. thus we brake the bigger size of calcareous material.
Opc cement is ordinary portland cement and in general concrete construction when there is no exposure to sulfates in the soil or groundwater opc is the most common cement which is used. for almost all structural work including all kinds of concrete construction, opc is an ideal building material and is one of the most commonly and widely used.
