X-ray radiation shielding properties of cement mortars
The types of aggregate used play an important role in determining the effectiveness of X-ray radiation protection of cement mortars. Cement mortars were prepared using fine aggregates obtained from six different sources. The influence of aggregate type on X-ray shielding properties was studied. The results showed that Researchers have incorporated barite, magnetite, limonite, scrap iron, and other materials into ordinary concrete to further enhance its performance with regards to radiation shielding [20–22]. Baalamurugan et al.

Feasible use of recycled CRT funnel glass as ScienceDirect
The recycled CRT funnel glass can be utilized as a fine aggregate for making concrete. The relatively high density (∼3000 kg m −3) of the glass as compared to conventional natural aggregates (∼2600 kg m −3) renders it suitable for producing heavyweight concrete.This present study aims to assess the feasibility of using recycled Green high strength concrete containing recycled waste ceramic aggregates and waste carpet fibers: mechanical, durability, and microstructural properties.
