Textiles can be made from many materials. These materials come from four main sources: animal (wool, silk), plant (cotton, flax, jute), mineral (asbestos, glass fibre), and synthetic (nylon, polyester, acrylic). In the past, all textiles were made from natural fibres, including plant, animal, and mineral sources. In the 20th century, these were supplemented by artificial fibres made from petroleum.

CEMENTS

"""
A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel (aggregate) together
[...]
Cements used in construction are usually inorganic, often lime or calcium silicate based, which can be characterized as non-hydraulic or hydraulic respectively, depending on the ability of the cement to set in the presence of water (see hydraulic and non-hydraulic lime plaster). 
"""

    * non-hydraulic cement

"""
Non-hydraulic cement does not set in wet conditions or under water. Rather, it sets as it dries and reacts with carbon dioxide in the air. It is resistant to attack by chemicals after setting. 
"""


    * hydraulic cement

"""
Hydraulic cements (e.g., Portland cement) set and become adhesive due to a chemical reaction between the dry ingredients and water. The chemical reaction results in mineral hydrates that are not very water-soluble and so are quite durable in water and safe from chemical attack. This allows setting in wet conditions or under water and further protects the hardened material from chemical attack. The chemical process for hydraulic cement was found by ancient Romans who used volcanic ash (pozzolana) with added lime (calcium oxide). 
"""


    * magnesium cement


    * concrete

"""
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past, limebased cement binders, such as lime putty, were often used but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (named for its visual resemblance to Portland stone).[2][3] Many other non-cementitious types of concrete exist with other methods of binding aggregate together, including asphalt concrete with a bitumen binder, which is frequently used for road surfaces, and polymer concretes that use polymers as a binder.

"""
Polyurea has become a preferred long term solution for narrow boats. The traditional coating with bitumen, known as "blacking" is being replaced with the practice of polyurea coatings. The clearest advantage is that it is not necessary to reapply a coat every 3–4 years. It is thought that polyurea coatings last 25–30 years.[5]

White gorilla glue is my go-to glue for everything. It cures in about an hour and usually stops foaming out in 30 minutes.

Lightly spray your joint to be glued prior to applying the glue. To prevent the glue from foaming out where you do not want, simply apply tape to that area. You can use painter's tape for this and then remove it later. The foam will give long before the glue does.

Gypsum Plaster/Powder is a building material used for the protective or decorative coating of walls and ceilings and for moulding and casting decorative elements.[1]  In English "plaster"/Powder usually means a material used for the interiors of buildings, while "render" commonly refers to external applications.[2] Another imprecise term used for the material is stucco, which is also often used for plasterwork that is worked in some way to produce relief decoration, rather than flat surfaces. 
The most common types of plaster/Powder mainly contain either gypsum, lime, or cement,[3]  but all work in a similar way.  The plaster is manufactured as a dry powder and is mixed with water to form a stiff but workable paste immediately before it is applied to the surface.  The reaction with water liberates heat through crystallization and the hydrated plaster then hardens.

"""
A thin film is a layer of material ranging from fractions of a nanometer (monolayer) to several micrometers in thickness. The controlled synthesis of materials as thin films (a process referred to as deposition) is a fundamental step in many applications. A familiar example is the household mirror, which typically has a thin metal coating on the back of a sheet of glass to form a reflective interface. The process of silvering was once commonly used to produce mirrors, while more recently the metal layer is deposited using techniques such as sputtering. Advances in thin film deposition techniques during the 20th century have enabled a wide range of technological breakthroughs in areas such as magnetic recording media, electronic semiconductor devices, Integrated passive devices, LEDs, optical coatings (such as antireflective coatings), hard coatings on cutting tools, and for both energy generation (e.g. thin-film solar cells) and storage (thin-film batteries). It is also being applied to pharmaceuticals, via thin-film drug delivery. A stack of thin films is called a multilayer.

Penetrating oil, also known as penetrating fluid, is very low-viscosity oil. It can be used to free rusted mechanical parts (such as nuts and bolts) so that they can be removed, because it can penetrate into the narrow space between the threads of two parts.  It can also be used as a general-purpose lubricant, a cleaner, or a corrosion stopper. Using penetrating fluids as  general-purpose lubricants is not advisable, because such oils are relatively volatile. As a result, much of the penetrating oil will evaporate in a short amount of time, leaving little residual lubricant. 
Other uses include: removing chewing gum and adhesive stickers, lessening friction on metal-stringed musical instruments, various gardening purposes and household repair tasks.

Typically it is spun into ropes or fabric sheets that can be used as such or as an ingredient in composite material components. 

Kevlar has many applications, ranging from bicycle tires and racing sails to bulletproof vests, because of its high tensile strength-to-weight ratio; by this measure it is five times stronger than steel.[2] It also is used to make modern marching drumheads that withstand high impact.  It is used for mooring lines and other underwater applications.

Titanium: The fast-and-light choice
In 1999, the MSR product catalog declared: “You want light? You want strong? You want Titanium.” Indeed, titanium’s biggest advantage is its ultralight performance. Titanium is 45% lighter than steel and stronger than aluminum. It is the lightest cookware material you can buy before you must sacrifice strength. It’s also corrosion-resistant, offering great durability.
Titanium pots are ideal primarily for boiling water because they can be made with thin walls, and transfer heat very quickly. Like stainless steel pots, they tend to develop hot spots, making them less than ideal for cooking real meals. Titanium is favored by the truly fast-and-light crowd, who count their grams and opt for quick boil-only meals after a long, exhausting day.

but great for boiling water

over open fire?
"Stainless steel and titanium pots may be used over open fire—with caution. You should expect some soot, and if you place the pot in too hot of an environment, some warping."

do titanium bits have coatings?

* Radiant barrier (like Reflectix)

https://en.wikipedia.org/wiki/Radiant_barrier
"""
A radiant barrier is a type of building material that reflects thermal radiation and reduces heat transfer. Because thermal energy is also transferred by conduction and convection, in addition radiation, radiant barriers are often supplemented with thermal insulation that slows down heat transfer by conduction or convection. 
A radiant barrier reflects heat radiation (radiant heat), preventing transfer from one side of the barrier to another due to a reflective, low emittance surface. In building applications, this surface is typically a very thin, mirror-like aluminum foil. The foil may be coated for resistance to the elements or for abrasion resistance. The radiant barrier may be one or two sided. One sided radiant barrier may be attached to insulating materials, such as polyisocyanurate, rigid foam, bubble insulation, or oriented strand board (OSB). Reflective tape can be adhered to strips of radiant barrier to make it a contiguous vapor barrier or, alternatively, radiant barrier can be perforated for vapor transmittance.

Construction: Joist

"a length of timber or steel supporting part of the structure of a building, typically arranged in parallel series to support a floor or ceiling."

"""
A joist is a horizontal structural member used in framing to span an open space, often between beams that subsequently transfer loads to vertical members. When incorporated into a floor framing system, joists serve to provide stiffness to the subfloor sheathing, allowing it to function as a horizontal diaphragm. Joists are often doubled or tripled, placed side by side, where conditions warrant, such as where wall partitions require support. 
Joists are either made of wood, engineered wood, or steel, each of which have unique characteristics. Typically, wood joists have the cross section of a plank with the longer faces positioned vertically. However, engineered wood joists may have a cross section resembling the Roman capital letter "I"; these joists are referred to as I-joists. Steel joists can take on various shapes, resembling the Roman capital letters "C", "I", "L" and "S".
