Effect of inorganic compound on artificial stones’ properties

Abstract

Many natural mines of decorative stones have been seen in the mountainous areas of the province Lorestan (Iran). Due to the traditional harvesting methods, these processes cause irreparable environmental damages. The formulation of decorative stone consists of travertine stone (TS) and marmarit stone (MS) with stone seeds 8-200 and 10-200. Cement, water, unsaturated polyester resin and fillers are used in the production of artificial stone composites from lesions of stone factory. The mechanical properties of TS with grain of size 10-200 are better than other grains and stones. The compressive strength of the samples was increased by reducing water content to 25 % and increase of unsaturated polyester resin percentage to 12 %. To improve the properties of the samples and minimization of their pores, we used fillers such as calcium carbonate, silica, silane, titanium dioxide and zinc oxide. Calcium carbonate causes softening and loss of the composite samples. The results showed that use of the fillers including micro-silica, silane and titanium dioxide increases mechanical properties and eliminated close to all pores significantly. Unlike the concrete, artificial stone composite obtained in the absence of water pool showed better properties that increase with time.

Chemical variability of artificial stone powders in relation to their health effects

“…Artificial stone (AS) is a composite material realised assembling powders, and occasionally fragments, of natural stones with a binder 1–5 . Recent kinds of AS mainly employ unsaturated polyester resins 6 as binder 7,8 , the filler eventually being waste material from the manufacture of natural stone 9 . These ASs exhibit good technological features and they are generally used to realise kitchen and bathroom countertops 10 .…”

“…Other natural or synthetic mineral phases are included to confer to the final stone specific appearances 9 or technological properties (e.g. porosity, hydrophobicity, …) 7,8 .…”

Development of Sustainable Artificial Stone Using Granite Waste and Biodegradable Polyurethane from Castor Oil

“…Several researches have been carried out in order to develop the most differentiated artificial stones, varying the types of aggregates and polymeric resins [12][13][14][15]. Shishegaran et al [12] evaluated the mechanical properties of three artificial stones containing: traveline powder and sludge, traveline powder and sand and traveline powder, sand and sludge, using two distinct epoxy resins.…”

Mechanical and physical investigation of an artificial stone produced with granite residue and epoxy resin

“…11 There are many academic researches that aim towards the production and characterization of this type of materials, using many different variations of residues and resins. Peng and Qin 12 investigated the mechanical properties of an artificial stone made of SiO 2 residue and quartz sand; Sarami and Mahdavian 13 studied the properties of artificial stones using travertine, marmarit stone with cement, water and unsaturated polyester resin. Baramaleki and Mahdavian 14 also developed an artificial stone using the same material of Sarami and Mahdavian 13 however, they used TiO 2 , ZnO and SiC nano-fillers to evaluate its effects on properties.…”

Borsellino et al 15 developed different artificial marbles using epoxy or polyester resin varying the power concentration of marble particles.…”
