    to use higher-strength concrete, when serviceability considerations may start to control the design process. 1 As an example, if a higher value of modulus could be achieved, slab spans could be increased without increasing thickness. Use of high-strength concrete can also lead to lower shrinkage and creep values.

    Compressive Strength Of Concrete

    Compressive Strength of Concrete at 7 days and 28 days. Concrete continues to hydrate and to gain strength for years after it is poured. Concrete gains strength due to the chemistry of the hydration of the cement. Essentially the cement continues to hydrate while there is moisture available which it can simply take from the air in most cases.

    Aggregate Crushing Value Test

    Aggregate crushing value test provides strength of aggregates for resistance against crushing under loads and is used for roads and pavements construction. Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load.

    Oct 15, 2018 Since the tensile strength of concrete is much lower than its compressive strength (approximately 10 times), concrete belongs to the group of brittle materials but it is not perfectly brittle. Concrete is considered to be a quasi-brittle material, and therefore, when analyzing the cracking behavior of concrete, not only tensile strength but ...
