U Utilization of recycled concrete in the construction of a system of ideas for theutilization of waste debris that often cause problems for the environment.Utilization of waste can reduce excessive buildup and reduce the environmentalproblems that exist, and can reduce the cost of economical manufacture ofconcrete. The composition used to be seen as a decrease in compressive strengthof cement respectively; fine aggregate; coarse aggregate; water is 1;1;1.5;0.5,while the composition is used to see the effect on the composition of the waste isthe result of trial and error with compressive strength of 30 MPa plan. Waste willbe used as a substitute for coarse aggregate with levels of 0 %, 50 % and 100 %.Slump 120 mm. The test object used cylindrical diameter 15 cm and height 30 cm.The compressive strength of concrete tested at the age of 7 days 14 days and 28days. Compressive strength of concrete with a mix of building waste debris fell by30,24 % with a 50 % level of debris, and 35,42 % with levels of 100 % pureconcrete rubble on (0 % debris). Composition effective for plan compressivestrength of 30MPa is straight cement; sand; split; water is 0 % debris 1,1.5,2,0.5,and for 50 % of debris 1; 1.2; 1.5; 0.5. The cost of making concrete with levels 50% less waste with levels of 4.81 % of the cost of manufacture of concrete 0 %waste.
