AI Technical Summary
The existing vitrified microbead fire-proof mortar has poor crack resistance and is dry and shrinking during construction, which can easily lead to cracks and leakage of fire-proof mortar, resulting in a decrease in thermal performance of the fire-proof system and cannot meet the high-demand steel structure material needs.
The fire-proof mortar is adopted for white cement-based steel structure, and the preparation ingredients include white cement, heavy calcium powder, vitrified microbeads, lime powder, propyl trimethoxysilane, polyacrylate, gypsum, polypropylene staple fiber and additives. Through specific stirring and spray treatment processes, the fire resistance, heat insulation, waterproof and bonding properties of the mortar are improved.
It has achieved excellent fire resistance, good heat insulation, excellent waterproof performance, strong adhesion and low water absorption, and has met the performance requirements of high-demand steel structure fireproof mortar, and has good construction performance and is convenient to use.
