“…In all concrete applications, fiber has led to remarkable developments in a variety of forms and shapes. As a result, many researchers had used the fiber to enhance the HWC specifications [69]- [73] A gap still exists regarding the correct geometry for highdensity fibers, and the use of high-density fibers in order to increase their ability to isolate harmful radiation such as gamma rays [70] In spite of the wide range of applications for which HWC is used, the material is best known for its use in radiation insulation for high energies [58], [74]. Also, HWC mainly aims to attenuate the radiation, thus the thickness of the structure made from the HWC is more.…”

With revolutionary advancements in technology, it is inevitable to not to develop the quality of concrete as it now a basic requirement for infrastructure. The objective of this review is to highlight the main aspects of Heavy Weight Concrete which covers the general concept of radiation physics being used in HWC, advancements in HWC technology, applications of HWC, cost optimization of HWC and future challenges. Recent researches have shown the requisite for Heavy Weight Concrete as it can efficiently absorb attenuate the radiation thus it is being used in nuclear facilities, medical facilities and now it is even being used in modern warfare. According to the past studies it is found that HWC can be used for shielding from high level radiations such as alpha-rays, beta-rays, X-rays and gamma-rays. Some of the rays propagated form radioactive material can be halted easily but some rays possess ultra-penetration ability and can penetrate through living being near them which results in destructive ionization of biological cells of a living being. This comprehensive review reaches out to the several critical areas such as future uses of HWC, cost optimization in HWC can be done by adding industrial residue of steel, glass, plastic fibers and other natural materials that can be used in HWC and increasing atomic mass for producing high quality radiation attenuation concrete.

“…Moreover, the replacement of cement or natural aggregates in concrete composition can involve either mass or volumetric replacement, while other parameters remain unchanged [17]. Finally, some researchers have preferred working with the concrete equivalent mortar (CEM) method, considering the cementitious matrix present in recycled aggregates in the newly formulated concrete's cementitious matrix [18][19][20].…”

Aggregates recycled from construction sites may exhibit slightly inferior characteristics compared to natural aggregates in terms of porosity, friability, and variability. However, it must be acknowledged that although recycled aggregates are currently used only in small proportions for manufacturing concrete, their usage is steadily increasing. It is now widely recognised that the reuse of recycled aggregates in mortar and concrete significantly contributes to the preservation of alluvial aggregates. The valorisation of recycled aggregates in concrete and mortar offers a clear economic advantage in the construction sector. Indeed, the reuse of materials from demolition could be envisaged directly on site or at construction waste recycling and treatment platforms. Additionally, it should be noted that to date, there is no specific standard for measuring the water absorption of recycled aggregates. Regarding the physical properties, the estimation of the absorption kinetics of the recycled aggregates has proved necessary. Moreover, other equally important measurements must be undertaken to determine all the other properties. The results obtained demonstrated that a good correlation exists between the substitution rate and the physical and mechanical properties of the prepared concrete. Furthermore, it was decided to vary the substitution rate of natural sand with recycled sand during the manufacture of concrete according to the following percentages: 25% recycled sand with 75% natural sand, and 50% recycled sand with 50% natural sand.
