Concrete Manufacturing Process A good quality concrete is essentially a homogeneous mixture of cement coarse and fine aggregates and water which consolidates into a hard mass due to chemical action between the cement and water Each of the four constituents has a specific function The coarser aggregate acts as a filler
3 ·Stage of Cement Manufacture There are six main stages of the cement manufacturing process Stage 1 Raw Material Extraction/Quarry The raw cement ingredients needed for cement production are limestone calcium sand and clay silicon aluminum iron shale fly ash mill scale and bauxite The ore rocks are quarried and crushed into smaller pieces of about 6 inches
10 Cement packaging and shipping The cement is then housed in storage silos from where it is hydraulically or mechanically extracted and transported to facilities where it will be packaged in sacks or supplied in bulk In either case it can be shipped by rail car freighter truck or ship

·The cement production process 1 The Quarry The cement production process begins with the extraction of limestone and clay from the quarry 2 Crusher and Pre Blending The material is then crushed to reduce particle sizes and blended to reduce variability in composition 3 Raw Mill and Kiln Raw materials and additives are
·3 Batching Batching is the process of measuring concrete mix ingredients by either mass or volume and introducing them into the mixer To produce concrete of uniform quality the ingredients must be measured accurately for each batch Volume batching Weight batching Volume batching • This method is generally adopted for small jobs
·The diagrams illustrate the phases and apparatus to make cement and how cement is utilised in the production of concrete for construction The production of cement involves a 5 stage linear process that begins with the mixing of raw materials and culminates in the packaging of new cement Making concrete is a simpler process that involves
·The cement industry plays a critical role in global carbon emissions primarily due to the release of CO 2 during the production of cement The process of cement production involves the transformation of raw materials such as limestone and clay into clinker which is a powdered form of cement
·The impact of improved manufacturing efficiency of cement and the effect of increasing global cement substitution by SCMs were determined as reduction of GHG emissions for a cubic meter of
