The use of alternative aggregate like manufactured sand is a natural step in solving part of depletion of natural aggregates. The investigation on alternative material for self- compacting concrete making started in recent times. Concrete made from manufactured sand waste as fine aggregate will be studied for workability, compressive strength, Split tensile strength and Flexural strength. Further, study of its durability will ensure greater dependability in its usage. So here in this project, manufactured sand has been used as replacement of fine aggregate by different percentage for making concrete of M- 25 and M-30. The percentage replacement will be 0%, 10%, 20%, 30%, 40%, 50% with natural fine aggregates. Cubes, beams and cylinders will be casted and tested compressive strength, Split tensile strength, and flexural strength as well as for durability properties. Optimum replacement of manufactured sand can be used in structural concrete. Key words: Manufactured Sand; Self-compacting concrete; Workability; Compressive strength; Literature review; etc… I. Introduction Every years waste material deposited in huge quantity on valuable land. This problem of utilization waste material can be solved up to certain level if people start use of it. Here, they had studied about use of waste Manufactured Sand as partial replacement of fine aggregate in self-compacting concrete. The Self-Compacting Concrete is the modern concrete which does not require compaction and vibration for placing of it,‖ It is able to flow under its own weight and completely filling formwork and achieving full compaction even in closely spaced Steel designed.’’ The harden SCC has same engineering properties and durability as tradition vibrated concrete. It is also eco-friendly. Self-Compacting Concrete was first developed in japan in early 1980. The flowability is the main property of SCC so that it can be placed under its own weight without any type of mechanical vibration and compaction. In order to make SCC of high fluidity without bleeding or segregation during the transportation or placing, the use of high powder content, super plasticizers (SP) and viscosity modifying ad mixtures (VMA) used for making this type of concrete. However, the cost of this type of concrete is slightly higher than normal vibrated concrete. A. Manufactured Sand Manufactured sand is obtained from the raw material. After washing the raw material the manufactured sand is separated by sieve s ize 1.18 of raw material. Raw material is washed for taking out the clay material which is useful for making the tiles. In the raw material about 10% is clay which is supplied to the cera mic factories. Fro m the raw material different size of manufactured sand are s e p a ra t ed by different size of sieve. Sand size of 30 meshes to 80 meshes (500 micron) is used in the glass industries. Sand size 1.18mm to 600 micron can be used in making concrete mix as the partial replacement of fine aggregate. The first industrial uses of crystalline manufactured were probably relat ed to me tallurgical and glass making activities a fe w thousand years BC. It is a key raw material in the industrial revolut io ne specially in glass, foundry and ceramic industries. No wadays silicon n is used in i n formation technology products like plastic of computer mouse and providing the raw material for silicon chips. For industrial pure deposits of manufactured sand capable of yielding products of at least 95% manufactured are required. B. Use of M- S and ฀ Glass ฀ Foundry casting ฀ Ce ra mics ฀ Filtration
