These results have been verified and demonstrate the viability and effectiveness of utilizing high-strength, fast-hardening concretes in their production. The use of high-strength concrete enables a reduction in plate thickness by 2 to 3 times compared to conventional concrete grades. PC Lira can be used to a limited extent for modeling shock effects on reinforced concrete structures by applying impulse loads, as it does not have the ability to use the shock interaction of different bodies with the penetration of one into another.

Introduction The use of reinforced concrete in fortifications is becoming more relevant with the emergence of new high-strength fast-acting concrete (Dvork і n et al (2017); Babych et al (2018); Sobczak-Piastka et al (2020)).
