    Concrete is a construction material that is extensively used because of its excellent properties such as durability, workability, satisfactory strength, and the easy availability of raw materials (cement, aggregates, and water), which are used to produce it [].By definition, concrete is a composite material that consists of a binding medium and aggregate particles and can be formed in several   Durability of concrete and cement composites summarises key research on these important topics. After an introductory chapter, the book reviews the pore structure and chemistry of cement-based materials, providing the foundation for understanding the particular aspects of degradation which are discussed in the following ://

    PFA grouts: selection of materials and flow properties. Performance of hazardous grouts. Non-structural void filling. Restabilization of masonry bridge structures. Experience of grouting performance in the Channel Tunnel and Cairo Waste Water Project. Part 4: Using PFA in concrete. What PFA does to concrete. Concrete properties. Durability of Derived from a workshop on rational design of concrete structures held in Hakodate, Japan, in August , the book provides a focus for debate about the ways in which concrete technologies around the world must respond to the necessity of ensuring that concrete construction achieves higher levels of durability, and about the growing imperative

In addition to pfa concrete, comparable ordinary Portland cement (OPC) concrete was available for sampling at all the locations ://?DocId= Concrete Durability is a comprehensive, practical guide for engineers involved in designing concrete structures of all types.

Featuring contributions from leading practitioners and academics in the field, it combines a thorough but accessible exposition of the principles of durable concrete design with a practical, hands-on approach to its application in construction :// "Concrete Durability by Thomas Dyer is a must-have guide for all professionals working in a concrete-related field.

Overall, this is a great book written in a coherent and logical format; it offers a substantial review of the subject, exploring many of the wide-ranging issues that are related to the durability of concrete." › Books › Engineering & Transportation › Engineering.

There is Fly ash or Pulverised fuel ash. Fly ash, also known as pulverised fuel ash (pfa) is the ash resulting from the burning of pulverised coal in coal-fired electricity power stations. The ash is very fine and it is removed from the flue gases by electrostatic precipitators.

Durability of concrete • Durability of concrete may be defined as the ability of concrete to resist: −weathering action, −chemical attack, and −abrasion while maintaining its desired engineering properties.

• Different concretes require different degrees of durability depending on the exposure environment and properties ://GGBS as a durability and strength enhancer 1.
