Description
Concrete technology is being revolutionised by the development of very efficient synthetic chemical concrete admixtures, which given the properties of fresh and hardened concrete and make structures more durable.The book covers both the theory and practice of admixtures. It emphasizes their working mechanisms and so their optimal use. It offers an overview of the fundamental behaviour of Portland cement and hydraulic binders as well as of chemical admixtures, then describes their effects in concrete in terms of rheology, mechanics, durability and sustainability, while keeping in mind the fundamental roles in concrete technology played by the water/binder ratio and proper curing.
