Objective

The main objective of this project is to analyze

the performance of beams by partially replacingthe coarse aggregate with waste materials such asrubber, construction demolition & debris andgranite. We also compare the results

with conventional beam.

Advantages of Replacing

Materials

Sustainable development is achieved.

Land for dumping the waste is getting reduced. ost of construction is minimized. !nvironmental pollution is minimized. ost of transportation is reduced.

Conclusion

The following are the results of the e)perimentalinvestigation

Steel fiber provides 2uctility. =t allows beams todeflect more and it also arrests the crac> thatdevelops in the concrete

There by using waste materials environmentalpollution can also be minimized

Scope o) *urt,er 7or8

-t present with this project we have used onlysteel fibers and some waste materials toinvestigate some of the properties under cyclic

loadings. or future wor> we are going to analyze by

changing the parameters such ashanging load condition
