·Processing techniques basically involve crushing and screening in crushed stone aggregates while sand and gravel materials are processed using screening and washing methods These processes occur in an aggregate processing plant whose objective is
·Abstract Aggregate shape properties have a direct influence on the behaviour of pavement materials The crushing process is the main factor responsible for generating these shape properties; however there has hardly been any effort directed toward optimising the performance of pavement materials by altering the crushing techniques to produce aggregate
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 use a wet grinding process
·A concrete batching plant is used to mix various materials such as cement aggregates sand gravel or crushed stone and additives to produce concrete The mixing process occurs at the plant where these components are combined in predetermined proportions to achieve the desired concrete quality
