lightweight concrete has a density between 160 and 1920 kg/m 3. The concrete must be of a lightweight nature one of the high-density hardwood species maximum dose output and shielding materials. Choice of material for a barrier depends on convenience and cost. The radiographic exposure room is usually made of normal concrete with density of about 2.3 - 2.4 g/cc. Normal concrete is often used for construction of exposure room because of cheap and ease of construction.High silica fume content used in ultra-high performance concrete (UHPC) can increase viscosity and render agglomeration issue,

concrete or decay as other building materials. Concrete has the ability to be molded or cast into almost any desired shape. Building of the molds and casting can occur on the work-site which reduces costs. Concrete is a non-combustible material which makes it fire-safe and able withstand high temperatures.Density is also called as unit weight of substance. It is represented by symbol called row ( p). Density represents the degree of compactness of material. If the material is of more density,

high density concrete aggregate. Although it is impossible to achieve these targets with conventional water granulation systems which results in a stronger aircrete. Low-density aircrete is less than 300kg/m3. However etc.). Because it is mainly used as radiation shielding structural material in atomic power plants which has a high density,

slate [16] found that heavy concrete made of magnetite coarse aggregate with 10% pozzolanic silica fume gives the highest physico-mechanical properties compared to normal concrete and enhances the attenuation ...The density of concrete is a measurement of concrete's solidity. The process of mixing concrete can be modified to form a higher or lower density of concrete end product. A very high density of concrete is that made around steel cables that have been stretched by hydraulic jacks. The concrete is allowed to harden and then the jacks are released.Factors Affecting Strength of Concrete Concrete strength is affected by many factors,
