Aspects of Concrete Strength and Durability

Quality and performance of concrete have traditionally been assessed by its compressive strength. However, in marine tructures problems associated with pO()r durability, such as corro ion of the reinforcement are by far m re prevalent than problems related to strength. Tbus when structure in aggre ive environment (such as sea water) are considered, emphasis i placed not only on achieving a concrete with optimum strength

Contribution to the Concrete Strength versus Water

This is the foundation of the relationship between concrete strength and water-cement ratio. Numerous empirical formulas, so-called strength formulas, have been developed for this relationship; the Abrams’ formula for instance. These formulas estimate the concrete strength from the water-cement ratio only, and they are usually simple but have ...
