This study analyzed some physical and mechanical properties of concrete produced with barite (BaSO₄) aggregate supplied from MuÅŸ province of Turkey. Unit weight (UW), water absorption (%), ultrasound pulse velocity (UPV), Schmidt hardness (SH), modulus of elasticity (ME), compressive strength (CS), tensile strength (TS) and thermal conductivity (TC) of the concrete were analyzed. For the experiments, 6 series of concrete containing 0, 10, 20, 30, 40 and 50% volume of barite aggregate were prepared. To determine thermal conductivity coefficient, this ratio was increased to 100%. Experimental results for normal concrete and barite concrete were compared.

Key words: Concrete, barite, heavyweight concrete, thermal conductivity.
