6. Compaction of concrete Compaction of concrete is process adopted for expelling the entrapped air from the concrete In the process of mixing, transporting and placing of concrete air is likely to get entrapped in the concrete . It has been found from the experimental studies that 1% air in the concrete approximately reduces the strength by 6%.
9. Wet process In the wet process, raw materials are crushed to a diameter of approximately 20 mm by a crusher and mixed in an appropriate ratio using an automatic weigher, Then, with water added thereto, the mixture is further made finer by a combined tube mill with adiameter of 2 to 3.5 m and a length of 10 to 14 m into slurry with a water content of 35 to 40%.

Environmental impact is the major effect on human health as well as plant various types of unwanted substances and major prone areas they create unhealthy and unsafe environment and provide various kinds ...
Manufacturing Process Mining. The cement manufacturing process starts from the mining of limestone, which is the main raw material for making cement. Limestone is excavated from open cast mines after drilling and blasting and loaded on to dumpers which transport the material and unload into hoppers of the limestone crushers.
5 CEMENT –HISTORY In India, Portland cement was first manufactured in 1904 near Madras, by the South India Industrial Ltd.But this venture failed. Between 1912 and 1913, the Indian Cement Co. Ltd., was established at Porbander (Gujarat) and by 1914 this Company was able to deliver about1000 tons of Portland cement. By 1918 three factories were established.
The Cement Manufacturing Process While each cement plant may differ in layout, equipment, and appearance, the general process of manufacturing portland cement is the same: crushed limestone and sand are mixed with ground clay, shale, iron ore, fly ash and alternative raw materials. Some manufacturers grind the raw materials dry, while others ...
