1. Introduction
The interest for the use of residues like cement parts for the manufacturing of blocks is linked to its low cost of acquisition, high availability, and the preservation of the environment [1–9]. The amount of residues that the ornamental rocks industry produces in Brazil range around 1,610,000 t per year. The use of this residue for the production of blocks destined for construction work is a way to reduce the negative impacts on the environment caused by the improper disposal, and also to reduce the consumption of natural resources [10–18]. Most of these tailings are discarded in decantation ponds and landfills, which are formed by materials of high fineness generated by processes such as cutting, polishing, and glossing of marble and granite plates [10–21]. According to a publication of the ministry of cities, the housing deficit in Brazil is about 6.490 million units that correspond to 12.1% of homes in the country. Although there was a significant drop of the number of Brazilian housing deficit in comparison to 2007, which was around 10%, the Brazilian population rose from 184 million to 194 million, which represents an increase of 5.5%, lowering the reach of the increase of housing units [22]. Globally the problem of the housing deficit would be lessened if the rhythm of housing construction doubled in the next 15 years [23]. Seeking to reduce the edification cost of a residence and to contribute to the reduction of the housing deficit, it was obtained a composite material composed of cement, marble and/or granite residue, gypsum, EPS (Expanded Polystyrene), sand and water, with inferior cost in relation to the conventionally used building materials. The obtaining and use of such composite had also as objective a contribution to withdraw harmful residues (marble/granite, EPS and PET) from the environment. Cement, gypsum and sand are the conventionally used materials for the residential construction. The cement has plastic and reinforcement functions; the sand can present a fillment or a reinforcement function, depending on its relation with the cement; the gypsum has plastic and curing accelerator function. The EPS is also widely used in construction with plastic, thermal and fillment functions. The marble and granite had fillment function, reducing the amount of inputs in the concrete obtaining and increasing its resistance to compression.
