- Abstract
In this study, the impact of expanded perlite (EP) and expanded vermiculite (EV) on the refractory properties of magnesium potassium phosphate cement (MKPC)-based fire-resistant materials were investigated. The physical and mechanical properties of MKPC paste were tested, and its fire retardancy properties were studied in detail. The results indicate that the incorporation of EP or EV to MKPC-based refractories brings a notable improvement in the fire resistance and makes a reduction in the apparent density. However, compared with EV-MKPC, the porosity of EP-MKPC is larger and its moisture content is higher, so the thermal insulation performance of EP-MKPC is better than that of EV-MKPC at the same content.
