Minerals

Rocks are aggregates of minerals. So minerals are the basic building blocks of the Earth. Currently there are over 4,000 different minerals known and dozens of new minerals are discovered each year. Our society depends on minerals as sources of metals, like Iron (Fe), Copper (Cu), Gold (Au), Silver (Ag), Zinc (Zn), Nickel (Ni), and Aluminum (Al

EVALUATION OF VOIDS IN THE MINERAL AGGREGATE FOR

The concept of voids in the mineral aggregate (VMA) is considered fundamental in the design of dense-graded hot mix asphalt (HMA) mixtures. The term VMA describes that portion of the space in a compacted HMA pavement or specimen which is not occupied by the aggregate. Current mix design procedures including Superpave are largely based upon the

The Effect of Aggregate

Feb 12, 2021Moisture damage is known to be a key factor influencing the durability of asphalt pavements. This phenomenon will reduce the mechanical properties of asphalt mixtures due to its destructive effects on the adhesion of the bitumen-aggregate system and the cohesion of the bitumen membrane. The mineral properties of the aggregates of asphalt mixtures are one of the factors

Feldspar and mica. Key minerals for fine aggregate quality

Research on the aggregate-concrete interaction has proved feldspar and mica to be key minerals for concrete quality. Feldspars are predominant minerals in most Norwegian aggregates. A relation has been found between the strength of cement mortars and the type and condition of the feldspars present. Especially, the degree of feldspar alteration (saussurite, sericite) appears to be a primary
