Area of Science:

• Materials Science
• Nuclear Engineering
• Radiation Shielding

Background:

• Nanoparticles (NPs) enhance concrete shielding properties for bioradiation and nuclear reactors.
• Optimizing NP concentration is crucial for improving mechanical properties and pore structure in concrete shields.

Purpose of the Study:

• Introduce a novel coefficient, the experimental to theoretical density ratio, for mixed-NP concrete.
• Investigate the relationship between NP concentration and material density using mathematical and Monte Carlo methods.

Main Methods:

• Developed a novel coefficient based on mathematical principles.
• Utilized the Monte Carlo method for physical simulations.
• Analyzed the impact of various nanoparticle concentrations on mixture density.

Main Results:

• The density of the mixture is directly proportional to the change in nanoparticle concentration.
• Maximum density is achieved at a specific nanoparticle concentration, influenced by NP characteristics and void content.
• Formulated the probability of nanoparticle separation for very small radii.

Conclusions:

• The theoretical findings provide a basis for experimental validation in future research.
• The novel coefficient can aid in designing effective radiation shields for nuclear facilities.
