Experimental investigations for mechanical properties of reactive powder concrete under uniaxial load

Reactive powder concrete cube strength test and axial compression test is carried out on rigid compression-testing machine controlled by electro hydraulic servo valve at various curing conditions and steel fiber content. Strength grade is quantified by testing cube compressive strength and stress-strain curve is obtained by axial compressive test of reactive powder concrete. To compare different stress-strain curve, elastic modulus, peak strain, toughness number in compression and mechanical constitutive relation of material is analyzed . Meanwhile, against the design and analysis of bearing capacity on right section in engineering structures, a applicable nonlinear constitutive model is put forward. Therefore, the mechanical properties research of reactive powder concrete can provide theoretical support for actual engineering structures.
