Abstract EN
The effect of using recycled concrete aggregates (RCA) on the basic properties of normal concrete is studied.
First, recycled aggregate properties have been determined and compared to those of normal aggregates.
Except for absorption, there was not a significant difference between the two.
Later, recycled aggregates were introduced in concrete mixes.
In these mixes, natural coarse aggregate was partly or totally replaced by recycled aggregates.
Results show that the use of recycled aggregates has an adverse effect on the workability and air content of fresh concrete.
Depending on the water/cement ratio and on the percent of the normal aggregate replaced by RCA, the concrete strength is reduced by 5% to 25%, while the tensile strength is reduced by 4% to 14%.
All results are compared with previous research.
As new in this research, the paper introduces a simple formula for the prediction of the modulus of elasticity of RCA concrete.
Furthermore, the paper shows the variation of the air content of RAC.
