The process of fabricated construction for insulated-fireproof lightweight concrete (BNCC) components for H steel column and I steel beam
In this paper, a process of fabricated construction for insulated-fireproof lightweight concrete (BNCC) components for H column and I beam in steel structures was proposed, in which BNCC components include sheets and blocks used as fireproof covers for structural members of buildings. BNCC is produced from the mixed portland cement and waste additive of fly ash with the following advantages: small volume density (≤ 800kg/m3), low thermal conductivity and working capability at high temperatures up to 1000oC. The use of BNCC as a fireproof material can provide an economic and effective fire-resistant solution for civil and industrial buildings.
