Which cement is used in dam construction? Quora

Dec 22, 2018When placing a mass concrete structure, low heat of hydration concrete mixes are used to prevent the internal temperature of the concrete from reaching a temperature of over 148 degrees Fahrenheit. This is done by using a Portland Type 5 cement, or by using a high percentage fly ash design mix with up to 33% fly ash as the cementitious component of the mix.

Construction of Roller Compacted Concrete Dams in Hot

Roller compacted concrete (RCC) dams are attractive to many water and energy corporations around the world due to their ease in construction and low construction cost. The hydration of cement and the climatic changes on the convective boundaries are the two main heat sources for the temperature rise in the roller compacted concrete dams. Thus, changing the RCC placement schedule according to
