Abstract:
The demand for artificial stones has been growing a lot nowadays, as they have superior properties when compared to natural ornamental rocks, in addition to their aesthetic appeal, considering that they can present the most diverse colors and compose any environment. Brazil has been importing this type of material a lot, so research aimed at developing it is very important to economy of the country. The objective of this work is to produce an artificial stone from wollastonite powder agglomerated by epoxy resin, for this, a mixture was made and transferred to a metallic mold, under vibration and vacuum and, later compressed. The plates were subjected to density, water absorption and apparent porosity test, three-point bending tests and microstructural analysis. The developed stone showed high levels of water absorption and apparent porosity, confirmed by micrographs made by SEM, however the developed stone was considered to have very high mechanical strength
