What is aggregate crushing test?

The 'aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. ... Due to this reason, the aggregates used in road construction must be strong enough to withstand crushing under roller and traffic.

Why is aggregate crushing test done?

The strength of coarse aggregates is assessed by aggregates crushing test. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, aggregate possessing low aggregate crushing value should be preferred.

What is water absorption capacity?

Water absorption refers to the ability of material to absorb water when immersed in it and is represented with water absorbing capacity. Water absorbing capacity is defined as the ratio of the weight of water absorbed by a material in saturated state over the weight of the dry material.

Does water weaken concrete?

One of the most common mix mistakes made by the average concrete worker is adding too much water to concrete. ... A watery mix actively reduces the compressive strength of the dried concrete. Usually, every additional inch of slump in the concrete reduces the compressive strength of the final product by roughly 500 psi. AP

Where does the water go when concrete dries?

Concrete dries as the water inside it evaporates through its surface. As this water evaporates through the surface, water from deep within the concrete moves through the capillaries and up to the surface to replace it. As long as the surrounding air can hold more water vapor, evaporation continues. AP

How long does concrete last in water?

7 days
