Abstract
The use of recycled concrete aggregates (RCA) to replace part or all of the natural coarse aggregates (NCA) in the production of concrete has been on the increase. Such use helps in the preservation of the natural resources and in the reduction in the use of landfills. Research is needed to understand the effects of using RCA on the properties of concrete. This paper reports the results of an experimental study of the pushoff shearing strength of normal-strength plain recycled aggregate concrete (RAC). A total of twenty seven pushoff specimens were cast and tested. The percentages of replacement (PR) of NCA with RCA were 0, 20%, 50% and 100%. The results showed a 7% reduction in the shearing strength for PR of 20% and 50% and a 28% reduction for PR of 100%.
