Abstract:In This paper,the characteristics and mechanical prop-erties of high strength and super-high strength concrete(60-120MPa)based on slags and alkaline components are presented.This type ofconcrete can be produced as rapid hardening or super rapid hardeningwith high durability,energy saving and low cost.Based on experimentswith reinforced beams of this type of concrete,its deformation properties,process and characteristics of disruption are described.
