referenceE. García, A. De Pablos, M. A. Bengoechea, L. Guaita, M. I. Osendi, and P. Miranzo published 'Thermal Conductivity Studies on Ceramic Floor Tiles' in Ceramics International in 2011.
measurementCork has a density of 160–240 kg m−3, thermal conductivity of 0.045 W m−1 K−1, acoustic resistivity of 1.2 × 105 kg m−2 s−1, specific heat of 350 J kg−1 K−1, compressive strength of 1 MPa, and tensile strength of 0.85 MPa.
claimCork is suitable for use as a green flooring option due to its lightweight, compact closed-cell structure, very low permeability for both solid and gas, low thermal conductivity, and chemical stability.
claimTaheri et al. prepared a composite using cellulose nanofibrils (CNF) and ordinary Portland cement (OPC) in various proportions, finding that short CNF fibers improved mechanical properties, while long and entangled fibers reduced the density and thermal conductivity of the composite.
claimHempcrete possesses high density (600–1000 kg m−3), low thermal conductivity, acoustic insulation, vapour permeability, low energy demands, and CO2 adsorbing capacity, making it a potential replacement for regular Portland cement.
measurementSilica-mineralized lignin nanocomposite aerogel (LigSi) has a near-infrared (NIR) absorption of approximately 9% and a thermal conductivity of approximately 0.04 W m−1 K−1.
measurementCeramic tiles have a density of 2500–6000 kg m−3, thermal conductivity of 0.6–1.7 W m−1 K−1, specific heat of 1000 J kg−1 K−1, compressive strength of 125–250 MPa, and tensile strength of 25–50 MPa.
measurementThe TLA-4 sample of the lignocellulose-based aerogel developed by Sun et al. exhibits a thermal conductivity of 29.67 mW m−1 K−1 and a 74.1% enhancement in negative oxygen ions (NOI).
