Q: Why does blasting of marble in the quarry cause wastage for those who manufacture
marble products?
Answers
Answer:
Marble waste is generally a high polluting waste due to both its high alkaline nature, and its manufacturing processing techniques, which impose a health threat to the surrounding. The quarries and processing plants are littered with large amounts of waste products deriving from extraction, sawing, polishing. At present, no significant activities are in place to recover and reuse the ultrafine CaCO3 dust combined in waste slurries of marble processing plants. It can be helpful to considering these calcareous particles as primary or secondary raw materials for use in other production. The main objective of this paper is to study the production process of the marble and during the production process how much waste is generated during the production process. ABSTRACT KEYWORDS: crumb rubber, utilization, compressive strength, low cost, sustainable INTRODUCTION The word marble comes from Greek word mamaros which means shining stone. Marble is a non-foliated, granular metamorphic rock that is formed by metamorphism of limestone and dolostone. Marble is a Calcium Car-bonate (CaCO3).
Answer and Explanation:

At present, no significant activities are in place to recover and reuse the ultrafine CaCO3 dust combined in waste slurries of marble processing plants.

Marble is a non-foliated, granular metamorphic rock that is formed by metamorphism of limestone and dolostone. Marble is a Calcium Car-bonate (CaCO3). The term marble is also applied to Serpentine rocks that can be polished to high shine. These are the natural stones which can be shaped in form of blocks, slabs, tiles, etc. and are used for monumental and decorative purposes since antiquity; various civilizations have used dimension stone in many ancient building and monuments that have survived to the present day. Marble cutting industry produces large amounts of solid wastes on large areas, which are expected to increase as construction is continuously increased, owing to the fact that the world production of marble industry has been increasing annually in the recent years.
