  • Assessment of Recycled Aggregate Concrete

    Keywords: Concrete, Recycled aggregate properties, Performance of recycled aggregate concrete 1 Introduction The applications of recycled aggregate in construction have started since end of World War II by demolished concrete pavement as recycled aggregate in stabilizing the base course for road construction (Olorusongo, FT, 1999) Theaggregate concrete ,the slump test was about 10cm slump for 60 % coarse recycled aggregate concrete and increases as the percent of recycled aggregate decreases The compressive strength of recycled aggregate concrete with 60 % recycled aggregate, is about 76 % of natural aggregate concrete The compressive strength increases as thePerformance of Recycled Aggregate Concrete
