The expanded material has properties similar to natural aggregate, but is less dense and therefore yields a lighter concrete product. The production of lightweight aggregate begins with mining or quarrying the raw material. The material is crushed with cone crushers, jaw crushers, hammermills, or pugmills and is screened for size.

Aggregates: Physical Properties and Mechanical Properties

Physical Properties of Aggregate: Elongation Index The elongation index on an aggregate is the percentage by weight of particles whose greatest dimension (length) is greater than 1.8 times their mean dimension. The elongation index is not applicable to sizes smaller than 6.3 mm. The elongation index is the total weight of the material

Properties & Uses of Steel | Sciencing. Mechanical: As noted, the tensile strength of steel can range between 290 N/m 2 and 870 N/m 2.Adding carbon to steel makes it harder because of the way the carbon atoms in effect disperse themselves among the iron atoms in a way that makes dislocations of material very difficult, forming "grains" of Fe 3 C.
