Exp 3 4 Specific Gravity Water Absorption

Water absorption is a measure of porosity of aggregates and its resistance to frost action. Higher water absorption means more pores hence aggregate will be the considered as weak. Water absorption value ranges from 0.1 – 2.0% for aggregate normally used in roads surfaces. Aggregates with water absorption up to 4.0% are acceptable in base coarse.

EFFECT OF CRUSHER FINES ON STRENGTH AND

Crusher fines is a fine material formed during the process of comminution of rock into crushed stone or, less frequently, of gravel into crushed fine aggregate. In a properly laid out processing plant, this dust should be removed by washing. Other soft or loosely adherent coatings can also be removed during the process of the washing aggregate.
