What is the effect of age of concrete upon the water-cement ratio and strength curve?

The age of concrete significantly affects its water-cement ratio and strength. As concrete matures, its strength generally increases due to the ongoing hydration of cement particles, which leads to a denser microstructure. Initially, higher water-cement ratiOS may lower strength but are essential for workability; as concrete cures, the effective water-cement ratio decreases, contributing to strength gain over time. Ultimately, strength curves show that concrete continues to gain strength well beyond the initial setting period, often achieving substantial increases up to several months or years, depending on conditions.
