Abstract - This work will be centred on testing the
in tension investigators found that use of fibres in concrete supports in increasing the tensile strength carrying capability of concrete efficiently, so the use of fibres has been combined in this thesis work to attain satisfactory strength in both Compression and Tensile properties of Concrete.
Mechanical properties of concrete with variable proportions of Fibrofor fibre and also substituting some cement content with Plaster Of Paris waste up to 15 percentage as per the study accompanied by V.N.Kanthe, India, which will help in maintaining the mechanical properties of concrete without disturbing the strength of concrete and also help in waste management of Plaster Of Paris waste which are being discarded in ponds during Ganesh festival in form of statues which in turn helps in protective ponds and Surroundings.
Professors, Specialists and Researchers has used different fibres in the concrete in both their natural and artificial form, which helps in reducing the major weakness of concrete i.e., tensile strength of concrete. Some researchers has proved that use of fibres in concrete has improved the tensile properties of concrete and also the Crack resistance by their extensive research.
Tests are done for Tensile, Compression, Flexure and Workability properties of concrete and finding out the optimal percentage of Fibrofor fibres for 15 percentage of Plaster of Paris waste which will help in improving the bonding properties of concrete, thereby improving the overall strength and load carrying capacity of concrete in Compression, Tension and flexural tests of concrete. Different parameters of concrete has been tested and are tabulated in this report and are compared to the standards results as per Indian Standards.
Fibrofor Fibre is a revolutionary product introduced by Brugg Contec, Swiss Company which has a positive engineering history of over 30 years. They have also developed numerous fibres over the years most prominent types are Fibrofor fibres and Concrix fibres. The industrial process of manufacturing fibres takes place in very sophisticated and advanced plant which is approved by European Standards for building materials.
Based on the tests conducted it is found that with Cement replaced up to 15 percentage by POP waste, the percentage of Fibrofor fibres with 0.5 percentage yields good results in all the mechanical properties of concrete tested as per the codal requirements.
Fibrofor fiber is a microfibers or High performance fiber which is bundled, fibrillated construction with 3D fibernet aids in guaranteeing fast and constant spreading & linking of concrete and fiber through the concrete mass.

1. INTRODUCTION
Tests were done with POP waste collected from rivers and lakes and then use if in form of replacement of cement by varying their percentage.
Ever since the introduction of cement in 1824 by Joseph Aspadin, there has been a continual development in the field of concrete technology by improving and perfecting the various parameters of concrete day by day.
Compression tests were done for a total of 30 cubes of different ratios with standard mixing and casting procedure as specified by IS code books and curing were done for rapid setting time as per specifications provided in IS 9013(1978) which recommended curing of cubes in boiled water at a temperature of 100 degrees for 3.5 hours which is then removed and air cooled for 2 hours, then it is finally taken for compression test. The results were tabulated for 28 days as per the formula provided in IS 9013(1978).
Concrete with higher strength and workability has been used on construction of buildings such as Tall Structures, Dams, Bridges etc. but the Mass houses/Apartments in slum development boards cannot use High Strength concrete which will not be feasible in economic viewpoint, Hence alternate methods to achieve such Similar property concrete has to be made by widespread research. We all know that Concrete is feeble in tension but it is good in Compression so to increase the strength of concrete
