Development of the Strength of Concrete

Abstract

The rate of hydration, and consequently the time-related process of strength development of concrete, depends on the type of cement used. In Fig. 2.1,¹ the coefficient ${{\beta }_{t}} = {{f'}_{{ct}}}/{{f'}_{{c28}}}$ for concrete made of normal cement (Type I), of rapid

Figure 2.1. Coefficient ${{\beta }_{t}} = {{f'}_{{ct}}}/{{f'}_{{c28}}}$to describe the effect of concrete age on concrete compressive strength.
