The water–cement and water–binder ratios

This chapter is one of the shortest in this book but, in our opinion, it is the most important.When sustainability becomes the key design factor, themost important characteristic of concrete will no longer be its 28-day compressive strength, but rather its w/c or w/b. In fact, throughout this book, it will be shown that this number determines the conditions of hydration upon which the properties of both fresh and hardened concrete depend.
