Sustainable Construction Materials

One alternative to using traditional wood products is Hardie board. Hardie boards are sometimes substituted for wood siding because Hardie board offers sustainable benefits. It is constructed of concrete and stamped with an artificial wood grain to give it the appearance of wood siding. Hardie board is available in various thicknesses and lengths and may be cut to desired lengths. The benefits of using Hardie board instead of wood or aluminum siding are that it is durable and lasts for decades, it only has to be painted approximately every 20 years, it is an excellent insulator, it is termite resistant, and it has an appearance resembling real wood. Figure 11.15 shows a home with Hardie board siding. A precursor to Hardie board was masonite, which is also manufactured to resemble wood but is actually made of steam-cooked and pressure-molded wood fibers that are distintegrated by saturating them with 100 psi steam, then increasing the steam or air pressure to 400 psi and suddenly releasing them through a small opening to atmospheric pressure and then pressing and heating them to form a finished board.

Hardboard siding, also referred to as pressboard and “masonite,” is a composite of wood fibers (e.g., sawdust), wax, and a thermoset resin (e.g., phenol formaldehyde). The mixture is heated and pressed into sheets. Then, wood-grain embossed paper is laminated to the surface of the hardboard, and the sheets are cut to size. First introduced in the 1970s, hardboard siding was installed extensively from the 1980s to the 1990s. And then, the house of cards came tumbling down!
Low-cost system for radiometric calibration of UAV-based multispectral imagery

Spectralon, which is a fluoropolymer, has been the most used material for making targets for radiometric calibration (Milton et al. 2009). Such popularity is due to its high durability, which preserves its reflectance over a long time (Georgiev and Butler 2007, Milton et al. 2009). However, these panels are expensive, which makes their acquisition difficult. One attempt to resolve this issue is the use of alternative materials. Some alternative materials have been used in recent studies, such as Polyvinyl chloride (PVC) canvas (Herrero-Huerta et al. 2014, Del Pozo et al. 2014), Masonite hardboard painted in greyscale (Wang and Myint 2015, Poncet et al. 2019), and fabrics made from polypropylene (Deng et al. 2018, Guo et al. 2019).
