6 Special Cements for Concrete and Masonry Construction

Special cements are used to serve some specific functions in concrete and masonry construction. These functions can be altering the setting or hardening behavior of concrete, produce different architectural effects, enhance workability, impart water retention and plasticity of masonry, resist water penetration in walls or containment vessels, or reduces the cost of the cementing agent.

mass concrete and materials used for mass concrete - Civil

The mass Concrete can be defined as ‘Any volume of concrete with dimensions large enough to require measures to be taken to cope with the generation of heat from the hydration of the cement and attendant volume change to minimize cracking’. The mass concreting technique is used for a massive structure such as dams and large bridge piers and foundation. Mass concrete is basically concrete with a higher proportion of coarse aggregate and a lesser proportion of cement, Large size aggregates are pre

What Is Specific Gravity Cement | Why We Calculate

This specific gravity of cement ranging from 3.1 to 3.16 g/cc.By this statement, we may ensure that cement 3.1-3.16 times heavier than this water of this same volume, and it sinks in water.. Because the specific gravity isn't less than 1, every material consists of so many little pores, which can contain voids in it, and the material becomes useless when any void present in the material.
