classification of aggregates based on unit weight

classification of aggregates based on unit weight

in nature, minerals commonly have impurities present in very tiny amounts, usually 3 or less of the crystal by weight. these impurities dont change the primary chemistry. therefore, the mineral name, or species, doesnt change. they do, however, change some of the mineral s characteristics, so we use a sub-classification called a variety. changes in characteristics such as color can have a considerable
