Describe the engineering significance of rock forming minerals. [2070 Bhadra] [3]

Those minerals which are found in majority of rocks in significant proportion are called rock forming minerals.

Civil Engineering Significance of Rock-Forming Minerals:

• The civil engineers need to know the properties of the rocks precisely to enable them to consider different rocks for any required purpose, i.e, as foundation rocks, as road metal, as concrete aggregate, as building stones, as flooring or roofing material, as decorative material etc.All properties of rocks are , in turn, dependend on the properties of their constituent minerals.Thus, properties of civil engineering inportance such as strength, durability, and appearance of rocks can be assessed only with the knowledge of the minerals that form rocks i.e, rock-forming minerals.
• The economic minerals,since they are scare, do not influence the properties of rocks and hence irrelevant from the civil engineering point of view.However,if they happen to occur in large quantities,their economic val....

• The economic minerals,since they are scare, do not influence the properties of rocks and hence irrelevant from the civil engineering point of view.However,if they happen to occur in large quantities,their economic value will not permit them to be used as construction materials or as foundation sites.

NOTE : Only name of minerals and uses are enough for this question.
