HARDNESS DEPENDENCY ON FILLERS' NATURE IN ARTIFICIAL
MARBLE PRODUCTION
Abstract: This article investigates the relationship between the type of filler used in artificial marble production and the resulting hardness of the final product. It likely explores how different fillers influence the material's structural integrity and resistance to scratching or indentation. The article might discuss the impact of filler properties like size, shape, and chemical composition on the overall hardness of artificial marble.
Key words: Artificial marble, Fillers, Hardness, Material properties, Manufacturing
Artificial marble is a material rapidly replacing of the natural marble obtained by mixing cement, gypsum or resin-based polymer materials with fillers (marble,
calcite, gravel, travertine, quartz, etc.) [2]. Its properties are almost the same or better than those of the natural product. Furthermore, it exhibits high strength, low shrinkage, minimal water absorption, high resistance to corrosion by aggressive chemicals and to aging and the effects of weather, easy maintenance and high abrasion resistance [1]. Artificial marble has several advantages over natural marble:
• Any colored marble can be obtained.
• Some types of artificial marble allow for humidity control. Based on the compounds on its structure, it is capable of releasing water molecules from itself when the humidity of the house is low, and absorbing it when it is high.
• Lighter than natural marble.
• Because of artificial marble is prepared in a liquid state, it also allows to cover any spherical structures.
• Artificial marble can last longer.
• Artificial marble is considered environmentally friendly as it does not emit radiation.
In the preparation of artificial marble, two components binders and fillers are used. Depending on the nature of the used binder and fillers, the resulting artificial marble has different physical and chemical properties. In the scientific work, several types of artificial marble were prepared using resin-based polymer material as a binder, and the variation of physical properties of artificial marble was studied by samples prepared by changing the nature of the fillers on that basis.
Seven samples of artificial marbles were prepared in the research work with different fillers, which binder are resin-based polymers. The fillers for the samples were local raw materials that are more common in Turkmenistan. About a third of the territory of Turkmenistan is Karakum sand, and it was considered economically viable to use it as a filler for artificial marble, and the first sample was prepared on that basis. The second sample was made of pebbles with a diameter of less than 4 mm, the third sample was made of pebbles with a diameter of more than 4 mm, and the seventh sample was made of pebbles and calcite. A fifth sample was prepared from residual natural white marble stones in order to set up a production without
loss. Determination of the mineral composition of sand deposits [3] showed that the main part of their composition consists of silicon (IV) oxide. Scientific research conducted in Turkmenistan revealed the possibility of extracting quartz sand from them [4] and the sixth sample was prepared on that basis. The fourth model was prepared based on the samples of Koytendag's marble-structured rocks.
The strength of spatial structures is equal to the product of the number of contacts between particles (N) by the strength of each contact (Pk): P = NPk
By the equation it can be derived that the more crystals formed during hardening, the smaller they will be, therefore the more densely they will be contacted, the greater the number of contacts, the higher the final strength will be.
[5]
The sixth sample containing quartz sand as a filler showed the highest index -767.3 kg/cm2. The third sample containing pebbles larger than 4 mm in diameter showed the lowest result -350 kg/cm2. According to the results, it was found that the strength of artificial marbles made of resin-based polymer depends on the number of voids created between the filler and, as a result, depends on the nature of the fillers used.
