so i have attached my paper that I'm working on so you can kind understand what I'm trying to work on.For the testing method is simple i just had put 3 pieces of wood under water for 7 days and see what have changed the weight in the wood has increased and the wood has gotten more soft. i have attached the pics of the wood dry and one wet. need anything let me know asap thanks. more than happy to work on this together if it makes it easier
Running Head: LITERATURE REVIEW 1 LITERATURE REVIEW 5 Patrick Almeida CIVE2260 Submission#2 02/12/22 LITERATURE REVIEW Table of Contents Introduction3 Overview3 Literature Review3 Building Materials4 Fungi4 Association in Between5 Conclusion5 References6 IntroductionComment by Sangster, John: Patrick – You seem to be missing a key concept of this project that each submission is a smaller part of one cohesive paper. You’re supposed to be submitting (1) the literature review as a 400-600 word document, and (2) the experiment design as another 400-600 word document. There should not be an introduction/overview section in this submission, but these should show up again at the end in the completed paper. Water and unwanted moisture damage to wood, such as hardwood flooring, building structures like sheds, homes, and cabins can render the home unsuitable to live in while also causing a variety of health concerns. Wood damage not only detracts from the aesthetic appeal of a property, but it also encourages the growth of mildew, germs, fungus, and moulds all of which pose health risks. There are several types of water damage, according to “the Institute of Inspection, Cleaning, and Restoration Certification (IICRC)”. Overview The project's goal is to evaluate and assess the integrity and size of floor wood that has been exposed to water for an extended length of time. Rain, floods, and storms may cause damage to wood, as can leak plumbing lines, overflowing sinks and bathtubs, slab fractures, and leaking roofs and windows. When wood absorbs water/moisture, it expands and seems cupped, and long-term exposure causes humps and bulging in wood. The integrity of the various wood samples will be examined in this test, and the wood sample with the best water resistance will be considered for use in future wood floor construction. Literature Review Comment by Sangster, John: Your literature review flows really nicely and incorporates the references in an effective way. Good job. When exposed to water or excessive moisture without protection, wood can rot and mildew. Increased moisture content can cause wood to expand and shift. Water damage affects different types of wood in different ways. When dealing with water damage, it is critical to arm oneself with the knowledge and practical advice, which they might need to prevent themselves and their belongings from further trouble. Insulation issues, a broken washing machine hose, A leaking pipe, and a blocked sink, that aren't evident to the naked eye can all cause water damage. Water may cause the wood to rot, crumble, and fall apart, as well as allowing mould to grow. The longer water is allowed to soak into the wood, the more likely black mould will spread throughout your home (Assis, Brancheriau, Napoli & Trugilho, 2016).Comment by Sangster, John: Incorrect citation formatting. Please refer to the project manual. Natural disasters or human mistakes are the leading causes of water damage indoors (for example, flooding). Melting snow, strong rain, or sewer system overflow can all cause water to leak into a structure? Fungal growth is a considerable concern in damp or water-damaged construction materials. Dampness is an issue in 10 to 50 percent of buildings in North America, Japan, India, Australia, and Europe, according to the WHO. Many papers have documented the detrimental health impacts of moist construction materials and fungus development in homes, institutions, and workplaces. The link between type I allergy and fungal exposure development has been established. Clinical evidence relating individual metabolites, fungal spores, and/or hyphal fragments to specific health concerns, on the other hand, is insufficient (Assis et al., 2016). The fact that some people are hypersensitive to fungus while others have no reaction at all adds to the complexity of the situation. Building Materials Of the overall material components, concrete, paint, and plaster were the most likely to sustain fungal growth. They make up around 80% of liquid water-damaged, dampness, and condensation materials and building elements, together with gypsum, wood, and wallpaper. “tar-treated materials, textiles, Eternit, filler, grout, felt, vinyl, medium-density fibreboard (MDF), cork, carpets, vapour barriers, paper, bitumen, wood-wool cement, glue, cardboard, and Masonite” are all examples of tar-treated materials (Assis et al., 2016). Fungi A total of 45 fungal genera or species were found on samples of water-damaged building components in one investigation. Fungi were found in “5,353 and 4,241” of the samples, respectively. The fungus genus Penicillium was the most common (3,720 counts and 114,143 colonies). The most often found fungus were “Cladosporium sphaerospermum, Ulocladium, Acremonium, Aspergillus versicolor (1,421 counts and 44,665 colonies) and Chaetomium spp.” (Goodell, Winandy & Morrell, 2020) Association in Between According to research, different construction materials have their own linked mycobiota, much like food. Many ordination approaches demonstrated a link between Ulocladium spp., Acremonium spp., and Penicillium chrysogenum on moist wallpaper and gypsum. These funguses have been identified to produce neutral celluloses, which may be a common capacity of many indoor fungi that have established a home on moist walls. In soil, dust, and hyper-saline water, Mucor, Aspergillus, and Chaetomium species are prevalent (Goodell et al., 2020). They may be introduced with soil and they can withstand alkaline conditions in the concrete, sprouting when the concrete is moist. The findings given here can help the construction industry choose materials that are less vulnerable to fungal development (for example, glass fibre instead of wallpaper) and building material producers develop nontoxic, fungus- or water-resistant materials. Conclusion Any damage that seems to have mould stains should not be attempted to be repaired. Your flooring and furnishings may be saved if you hire a competent water repair firm. If you preserve any furniture or floor tiles that have been heavily damaged by water, you risk allowing mould to grow. ReferencesComment by Sangster, John: These are both good references.

Literature Review – 4.5/5: Your sources are good and your writing works well integrating those sources into the narrative. You’ve got some minor errors with your citation/refrence formatting (0.5/1 on that metric), and should check in with the project manual for details on that. Experiment Design – 0/5: You’re missing the experiment design portion of this document.
