Abstract The use of recycled coarse aggregates in processing
mix design and production of recycled aggregate concrete were
prepared by the crushing of tested concrete cylinders of
compressivestrength from 2000psi to 5000psi in the laboratory.
Then,we test the properties of fresh recycled aggregate concrete
and physical and mechanical properties of harden concrete in
contrastto natural aggregate concrete in the same mix
proportion. The test results showed,the shape and physical
properties of recycled coarse aggregates can reach the basic
requirement of normal concrete coarse aggregates after the
crushing. Proper grading recycled aggregate can produce
reasonable concrete smoothly.After processingtesrs of variant
physical and mechanical properties of recycled aggregate
concretewhich water-cement ratio from 0.5 to 0.7,it was found
that although its properties were worse than natural aggregate
concrete which is the control set,but the differenceis limited.
So,we''ve got a conclusion that it is suitable acceptability to
adopt recycledcoarse aggregate in the concrete production.
