Material Reconciliation 2011 | Construction Aggregate

Material Reconciliation We use material reconciliation to analyze and verify ingredients at the end of a production process It allows you to compare the material quantity that actually flowed in with the planned quantity or the quantity of the material producedWhat is cement reconciliation? - Quora,Each cement application is tracked for its consumption and wastage to put process and checks to keep it to minimum Reconciliation of any material is use to track the actual budgeted consumption and its wastage Periodic reconciliation helps in tracking the material budget and controls its ordering processCONCRETE MATERIALS AND TESTING,The manufacturing process known as the dry process is the most widely used at present This consists of grinding the individual raw materials and feeding at controlled amounts into a rotary kiln and burning until they fuse into small lumps or balls called clinkers In the wet process, a slurry of the blend is fed into the rotary kiln
