This paper presents the results of an experimental study to investigate the influences of high temperatures on the mechanical properties of concrete containing recycled fine aggregate. A total of 150 concrete prisms (100x100x100 mm) are cast and heated under five different temperatures (20oC, 200oC, 400oC, 600oC, 800oC ) for test. The results show that the mass loss, compressive strength ...

It is also noted that all the modulus of elasticity values of the concrete containing recycled aggregate fall below the BS 8110. This is not observed in the ACI 318 equation. Considering the BS 8110 equation as an upper bound, and using Figure 7, a simple mathematical model to predict the modulus of elasticity in the form of can be used to predict the modulus of elasticity (), is the ...
