A growing interest in designing high-alumina MgO-bonded refractory castables has been identified recent years due to the magnesia ability react: (i) with water at initial processing stages of these materials (inducing precipitation brucite phase) or (ii) alumina, giving rise situ MgAl2O4 generation high temperatures. Nevertheless, despite great potential caustic be used as a binder such systems...

This study evaluated the tension force of cast frameworks made by the technique of framework cemented on prepared abutments using two different resin cements. Forty multi-unit abutment analogs were individually fixed with chemically cured acrylic resin inside PVC cylinders using a parallelometer. Brass cylindrical abutments were tightened to the multi-unit abutments to be used as spacers and th...
