Construction of a dam involves huge amounts of Mass Concrete. The most important characteristic of Mass Concrete is its thermal behavior.

This chapter describes methods of selecting and adjusting various ingredient proportions of concrete with pozzolonic, slag, and admixture. It will teach readers how the procedure takes care of criteria of placeability, compactibility, consistency, flowability, strength, and durability of concrete mixtures. This chapter also teaches about the use of larger aggregate (150 mm) in Mass Concrete to have the requisite co-efficient of thermal expansion, and uses an example to explain mix designs of Mass Concrete in concrete gravity dam. Finally, this chapter educates the reader on batching, mixing, and production of concrete at compact batching plants, along with compaction and curing of concrete in water retaining structures such as a concrete gravity dam.
