Ceramic tiles as sustainable, functional and insulating materials to mitigate fire damage

Abstract

Owing to their lower costs and functional properties, the construction industry has been increasingly adopting synthetic organic polymer (SOP) materials into linings, interiors and non-load bearing structural components. While SOPs have favourable properties and characteristics at ambient conditions, the same materials often perform poorly under moderate-to-elevated temperatures such as that arising from a building fire. In fact, most SOPs tend to combust and decompose at elevated temperatures which, unlike traditional building materials such as concrete and ceramic tiles, is proven to not only contribute to the fire but also to adversely affect evacuation and firefighting operations. From a fire engineering perspective, this paper tests a hypothesis in which ceramic tiles (CTs) are expected to outperform SOPs and commonly used insulations as finishing and lining materials under fire conditions. As such, this study showcases a thorough comparison between the behaviour of commonly available CTs, SOPs and insulations in temperatures ranging between 25 and 1000°C. Then, this paper analyses published CT models to derive temperature-dependent material models with the aid of machine learning (ML). Findings of this work advocate the use of CTs as favourable finishing and interior lining materials to enable realising improved structural fire performance and fire response managements, as opposed to SOPs, composites or insulations. The outcome of this work is expected to be of interest to architects, first responders, building officials, fire and structural engineers.

Fourier-Transform Mid-Infrared (FT-MIR) Spectroscopy as a High-Throughput Phenotyping Tool for Measuring Total Fatty Acids in Chickpea (Cicer arietinum L.) Flour

“…Because molecular functionalities are characteristics of bond stiffnesses and atomic masses, the FT-MIR signals for nutritional traits should be universal, regardless of a sample’s environment of origin . Therefore, chemometric approaches based on multivariate calibrations such as partial least-squares (PLS) regression, multivariate regression (MLR), and artificial intelligence (AI) based neural networks (i.e., convoluted neural networks) can be applied to build strong predictive models (with supervised learning) targeting nutritional traits for HTP. − …”

A Study on the Flame-Retardant Performance of Recycled Paper Building Materials Manufactured by 3D Printer

“…The main cause of fire material damage and human injury is the use of low-cost combustible building materials, prioritizing economic feasibility and construction convenience. Therefore, the flame-retardant performance of building materials is an essential consideration to prevent the spread of fire [5].…”
