Damage analysis of POZD coated square reinforced concrete slab under contact blast
文献摘要：
High efficiency,environmental protection and sustainability have become the main theme of the development of the protection engineering,requiring that the components not only meet the basic functions,but also have chemical properties such as acid and alkali corrosion resistance and aging resistance.Polyisocyanate-oxazodone(POZD)polymer has the above characteristics,it also has the ad-vantages of strong toughness,high strength and high elongation.The concrete slab sprayed with POZD material has excellent anti-blast performance.In order to explore the damage characteristics of POZD sprayed concrete slabs under the action of contact explosion thoroughly,the contact explosion test of POZD concrete slabs with different charges were carried out.On the basis of experimental verification,numerical simulation were used to study the influence of the thickness of the POZD on the blast resistance of the concrete slab.According to the test and numerical simulation results that as the thickness of the coating increases,the anti-blast performance of the concrete slab gradually increases,and the TNT equivalent required for critical failure is larger.Based on the above analysis,empirical ex-pressions on normalized crater diameter,the normalized spall diameter and normalized spall diameter are obtained.
