Literature collection relevant to the research work has been made .Preliminary

experimental investigation on Self compacting concrete by partial replacement of fine

aggregate and coarse aggregate by recycled aggregates was conducted. Different

aggregates obtained from construction and demolition wastes were used in the

experimental investigation.The investigations were divided in to five modules In the

first module graded brick bats in various proportions were used as partial replacement

of coarse aggregates. In the second module recycled graded concrete was used as a

partial replacement of coarse aggregates In the third module graded rubber treated with

sulphuric acid was used as coarse aggregate by partial replacement. In the fourth

module manufactured sand was used by partial replacement for fine aggregate. In the

fifth module corrugated steel fibres and plastic fibres were added in suitable

proportions to the above said cases.Optimum mix proportions meeting the requirements

of SCC for all the cases was arrived on a trial and error basis. All the materials used for

the preparation of mix were tested to suit the requirements.The tests include (A)Tests

on cement (B)Tests on Fine Aggregate (C)Tests on Coarse Aggregate. List of

experiments conducted on fresh concrete sample include Slump Flow test, J-Ring,V-

Funnel,L-Box.The various strength test conducted are Compressive Strength

Test.Flexural Strength Test,Split Tensile Strength Test. Based on the test results the

influence of the various recycled materials on the strength parameters of SCC has been

studied. An article relevant to the study has been accepted to be published in a journal

which has been listed in Annexure II. As a continuation of the experimental

Investigation beam column joints are to be tested the structural laboratory of Mepco

Schlenk Engineering College Sivakasi. Validation of the test results is to be made using

software package.
