13. Density of high-density concrete is about ________
2400 kg/m3
2750 kg/m3
3000 kg/m3
3360 kg/m3
3360 kg/m3. The density of normal concrete is about 2400 kg/m3. The density of light-weighted concrete is about 1900 kg/m3.
For concrete to be termed as high-density concrete, it must have a unit weight ranging about 3360 kg/m3 to 3840 kg/m3, which is about 50% higher than the weight of conventional concrete. The high-density concrete is used in the construction of radiation shields.
