Crushing natural stone to produce artificial sand of the right size and quality is the most efficient and cost-effective method for obtaining a substitute for natural sand. This manufactured sand would be free of contaminants and of the required size and quality. ... The first stage in manufacturing Portland cement is mixing the four main basic ...

Artificial sand making has a bright future in the construction industry. The demand for artificial sand is increasing rapidly. Here are the few reasons why artificial sand making has a good market opportunity. At present, the artificial sand is nearly 50% cheaper than river sand. The river sand is being sold at around Rs 1,300 a tonne.

2.1.2 Preparation of solid catalyst-coated sand For use as additive manufacturing sand, sintered artificial sand (average particle size 106µm) was heated to approximately 120°C. The heated sand was then added with 60mass% metaxylene sulfonic acid aqueous solution by 0.3mass%, and the mixture was stirred for 10min.
