Specific gravities of heavyweight concrete aggregates are usually more than 4000 kg/m 3. Barite is the most common aggregate used for heavyweight concrete. Heavyweight concrete produced with barite has 1.25 meV of γ-ray absorption capacity. These are formulated as μ =0.055e 1.36c cm −1 ( c is barite percent in aggregate) …

77% of barite is used in the oil and gas industry as a weighting agent in exploration drilling. Barite can also be used in: heavy aggregate for multiple uses within the construction industry. radiation-shielding concrete e.g. for X-ray rooms; fillers in paint and plastics; sound reduction in engine compartments; friction products for ...

Materials for manufacturing barite mortar include [10]: • Cement: PCB40 cement and construction sand are commonly used. Yellow sand is carefully screened. • High content …

The replacement of the natural aggregate with barite in UHPC concrete resulted in a 12.8–21.1% reduction in compressive strength [18,45]. This result is due to the lack of enhancement in the interfacial transition zone between barite and cement paste and the disintegration of barite during the mixing process [45,74].

When using barite aggregate, the density of concrete is about 3400 kg/m 3, which is 45% higher than that of ordinary concrete; with magnetite the density is equal to 3500 kg/m 3 –by 50% higher than that of normal concrete and with hematite aggregate the density is approximately 3600 kg/m 3 —53% higher than normal concrete [107].
