Manufactured Aggregate Processing Flow. Whether using dry, wet or semi-dry processing of manufactured aggregate, the main equipment for crushing and screening is almost the same as that of manufactured sand. Feeder→soil removal→coarse, medium and fine crushing→screening→sand making→screening→fine powder separation→online monitoring.

Sand is the second most traded raw material after water. Since the demand for sand – among others in the concrete industry – is growing faster than suitable sand resources can be found, sand is instead produced from gravel or transported over long distances. Rhewum has developed a solution to process sand mobile and therefore directly on site.

Crushed sand can be of coarser and angular texture. This can lead to more water and cement requirement to achieve the expected workability. Manufactured sand can contain larger amounts of micro fine particles than natural sand, This can affect the strength and workability of the concrete. We are also using M-sand for current project.

The use of manufactured sand makes sense from various perspectives. First, manufactured sand is more uniform in structure compared with natural sand. It also has an advantage when it comes to concrete production, because manufactured sand is less needed in the concrete mix by a margin of 5 to 20% compared with natural sand to fill the voids

How Concrete is Made. In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.
