Special concretes - Mass concrete - Introduction, materials, thermal cracking

The lecture opens with the introduction of mass concreting including the guidelines to be followed during mass concreting. The materials used in mass concreting considering the requirements such as workability, heat of hydration and strength are addressed in the lecture. Thermal cracking is discussed in detail in the lecture. The lecture also discusses a case study involving raft concreting and the challenges involved in the construction and measurement of temperature differentials.
