Compression Strength Of Military Concrete

Uniaxial compression performance and stress–strain

1 Introduction In recent decades, the ultrahighperformance concrete (UHPC) have been increasingly widely applied in the bridge engineering , building and military engineering due to its higher strength, greater toughness, and more excellent durability Existing studies indicated that the UHPC prepared with traditional Portland cement had a denseConcrete is strong in compression but weak in tension The tensile strength is generally rated about 10 percent of the compression strength For thisCHAPTER 7

Compressive behaviour of concrete at high strain rates

Experimental techniques commonly used for high strainrate testing of concrete in compression, together with the methods used for measurement and recording of stress and strain, are critically assessed in the first part of this paper The physical capability of each loading method is discussed and some consideration is given to the definitions used for specifying the loadingThe compressive behaviour of concrete at high strain rate was more extensively studied in these last decades Many tests have been done in order toCompressive behaviour of concrete at high strain rates
