Notes:
Silicate fireproof coatings for tunnels (FCT) have many eminent properties. But low adhesionstrength and poor water/fire-resistance of this kind of materials largely limit its applications. Here wereported a new kind of FCT based on high alumina cement as principle adhesive, redispersible powder asassisting adhesive, ammonium polyphosphate as fire-retardant material, vermiculite as adiabatic padding,and magnesium hydroxide as assisting reagents. The influence of various experimental conditions on fireresistance, adhesion strength and water resistance were carefully studied. Results showed that dispersibleemulsoid powder was a key component affecting adhesion strength and water resistance of FCT, whereasfire-retardant material posed significant effects on the fire resistance
