چکیده مقاله:
Calcium carbonate is used as inert filler in rubber industry in the production of tires. Calcium carbonate is abundant and inexpensive, so it is widely used for cost reduction. Too, calcium carbonate is known as non- reinforcing fillers in rubber industry. Waste CaCO3 powder is a by-product of sawing marble and could be used as a replacement for the CaCO3 fillers that are currently used in rubber production. In the present study, particle size, specific surface area, and physical properties such as tensile strength, 300% modulus, hardness and elongation at break were studied. The results were found that made ruubers from waste calcium carbonate was getting higher hardness, modulus, elongation at break than standard. Eventually, waste CaCO3 powder was suitable for use in the rubber industry.
