However the conductivities of air, cement hydrates, and normal aggregate are all different.

In the present paper, MA and SP with high thermal conductivity are partially replaced with normal aggregates. Enlarging up to 42.3% of MA and 1.5% of SP for concrete volume, thermal conductivities of concrete are evaluated and the results are compared with those from several models like ACI122R Model, DEMM (Differential Effective Medium Model), and MEM (Modified Eshelby Model) which can consider equivalent thermal conductivity in three-phase composites.
where E is the modulus of elasticity in GPa, [F.sub.cu] is the cube strength in MPa, and R is the recycled aggregate to normal aggregate ratio.
Gradation of the normal aggregates was obtained using ASTM C136.
