Artificial Sand- CRF (Crushed Rock Fine)Artificial Sand which is manufactured by stone crushing. Crushed Rock Fine (CRF) have been used as fine aggregate in concrete for centuries. However, dredging river beds for River Sand is now banned in many places due to its adverse environmental impacts. On the other hand, CRF has the major problems of being angular in shape and containing excessive fines. To resolve these problems, the technology of processing (CRF) to improve the particle shape and reduce the fines content has been developed. Such processed (CRF) is called manufactured sand MS (Manufactured Sand). In this research, the particle shape, size distribution, fines content and packing density of MS (Manufactured Sand) are studied and the effects of using MS (Manufactured Sand) on the performance of concrete are investigated. The results showed that the use of MS (Manufactured Sand) can improve the workability of fresh concrete and, if advantage is taken to reduce the water content, can reduce the cement content or increase the strength of hardened concrete. There is, therefore, a high potential for engineering the various properties of MS to enhance the overall performance of concrete.
AggregatesCrushed Aggregate or simply "aggregate", is a broad category of coarse particulate material used in construction, including sand, gravel, crushed stone. Aggregates are a component of composite materials such as concrete and asphalt concrete. Ideal to be used in construction work, this product is precisely processed using latest techniques in compliance with the international quality standards. Apart from this, clients can avail this product from us in various sizes and quality as per their specific requirements. In concrete, an aggregate is used for its economy factor, to reduce any cracks and most importantly to provide strength to the structure. Increases the volume of concrete, thus reduces the cost. Provide dimensional stability. Influence hardness, abrasion resistance, elastic modulus and other properties of concrete to make it more durable, strong and cheaper.
