Experimental and Numerical Simulation on the Penetration for Basic Magnesium Sulfate Cement Concrete

Area of Science:

• Materials Science
• Civil Engineering
• Mechanical Engineering

Background:

• Ordinary Portland cement concrete (OPCC) is a widely used construction material.
• Understanding the penetration resistance of concrete is crucial for protective structures.
• New cementitious materials require thorough evaluation for their mechanical and protective properties.

Purpose of the Study:

• To evaluate the penetration resistance of Basic Magnesium Sulfate Cement Concrete (BMSCC).
• To compare the anti-penetration performance of BMSCC with OPCC.
• To analyze the influence of material properties and impact conditions on penetration.

Main Methods:

• Experimental preparation and characterization of Basic Magnesium Sulfate Cement Concrete (BMSCC).
• On-site penetration testing of BMSCC and ordinary Portland cement concrete (OPCC) targets.
• Numerical simulation using LS-DYNA to model penetration dynamics.

Main Results:

• BMSCC demonstrated significantly better penetration resistance than OPCC under identical conditions.
• Penetration depth, crater diameter, and crater volume were substantially smaller for BMSCC targets.
• Failure analysis revealed fewer cracks and less overall damage in BMSCC specimens.

Conclusions:

• Basic Magnesium Sulfate Cement Concrete (BMSCC) offers enhanced penetration resistance compared to traditional OPCC.
• The findings support BMSCC as a viable material for applications requiring high impact resistance.
• Further research can optimize BMSCC formulations for specific protective engineering needs.
