Development and characteristic of SFRCR-ECC as a novel multifunctional version of fire-resistive and corrosion-resistive coating
Ordinary fireproof coatings can retard the rise of temperature on the outer wall of steel pipes during building fires. However, they still have defects such as low tensile and compressive strength, limited ductility and toughness, and poor bonding with the substrate, etc. At the same time, twice coa...

| description | Ordinary fireproof coatings can retard the rise of temperature on the outer wall of steel pipes during building fires. However, they still have defects such as low tensile and compressive strength, limited ductility and toughness, and poor bonding with the substrate, etc. At the same time, twice coating of anticorrosive primer and fireproofing on steel substrate reduces both cohesive properties of the steel substrate. Under the influence of the environment, the coatings will develop large cracks or even peel off with the deformation of the structure. In response to the above problems, a spray-applied, fire-resistive and corrosion-resistive engineered cementitious composites (SFRCR-ECC) containing fly ash cenosphere (FAC), PP fibers and PE fibers was developed in this paper. The working properties, tensile and compressive properties, bond strength and durability of SFRCR-ECC were also systematically investigated. Due to the excellent durability and mechanical properties of SFRCR-ECC-30, it was selected as the optimal ratio, and its thermal conductivity and microstructure were investigated. SFRCR-ECC-30 would be the SFRCR-ECC coating sprayed onto concrete-filled steel tubular (CFST) columns subjected to fire. The successful development of SFRCR-ECC provides a new possibility for fireproofing of steel structures and provides the necessary basic data support for subsequent tests. |
