1. A method for manufacturing articles in form of a slab or block, said articles being obtained by means of a method during which an initial mix comprising aggregates and a binder undergoes vacuum vibro-compression followed by a step involving hardening of the binder, characterized in that the aggregates comprise synthetic aggregates and fillers with a hardness greater than or equal to 5 Mohs, wherein the synthetic aggregates and fillers have the following chemical composition by weight:
48%<SiO2<73%,
12%<CaO<30%,
1.5<MgO<11%,
1.0%<Al2O3<19%, and
0%<ZrO2<20%;
the SiO2 present being substantially only in amorphous form and in any case with a possible content of SiO2 in crystalline form less than 1% by weight;
wherein the binder used is of an organic nature and is an unsaturated polyester resin; and
wherein the chemical composition of the synthetic aggregates and fillers also comprises the following further components by weight:
0%<B2O3<10%,
0%<ZnO<10%,
0%<BaO<10%,
0%<Li2O<5%, and
0%<P2O5<5%.
