GMR Institute of Technology Fresh Concrete
Properties OF Fresh Concrete GMR Institute of Technology Introduction The potential strength and durability of concrete of a given mix proportion is very dependent on the degree of its compaction. It is vital, therefore, that the consistency of the mix be such that the concrete can be transported, placed, and finished sufficiently early enough to attain the expected strength and durability. Significance The first 48 hours are very important for the performance of the concrete structure. It controls the long-term behavior, influence f'c (ultimate strength), Ec (elastic modulus), creep, and durability.
Properties OF Fresh Concrete GMR Institute of Technology Elasticity and Strength Of Concrete The elastic properties of materials are a measure of their resistance to deformation under an applied load (but the elastic strain is recovered when the load is removed). Strength usually refers to the maximum stress that a given kind of sample can carry. Understanding these properties and how they are measured is essential for anyone wishing to use materials
