Reference excerpt

Geopolymer bonded wood composite (GWC) are similar and a green alternatives to cement bonded wood composites. These products are composed of geopolymer binder, wood fibers/ wood particles. Depending on the wood and geopolymer ratio in the material, the properties of the wood-geopolymer composite material vary.

Function The main functions of wood in the composite material are weight reduction, reduction of thermal conductivity and the fixture function whereas the main functions of geopolymer are bonding of wood particles, improvement of fire resistance, providing mechanical strength, improvement of humidity resistance and protection against fungal and insect damages. They serve similar functions and purposes like all other mineral bonded wood composites. The fact that the binder agent (geopolymer) are mostly produced from industrial residue and waste puts these materials at a greater advantage over other mineral bonded wood composites. However, most of the works under this topic remains at the research and development phase. Some of the core difficulties in production and commercialization of standardize product is the variation in the sources of the aluminosilicate binder and the cost involve in activating the binder. Currently, metakaolin binder remains as the one key source to produce or bind these products with huge variations in other sources of the binder such as slag, fly ash etc.

Uses The inherent properties and the incorporation of wood fiber and particles in this composite, has made it possible to produce GWC building materials that are light weight and has a variety of uses due to its heat storage capacity, for example in areas of thermal insulation, fire and noise protection. The wood-geopolymer composite material in the building walls can serve as a microclimate regulator absorbing the moisture when the air humidity is high and returning the moisture when there is a low air humidity period, thus improving the hygrothermal comfort in the building.

Commercialization Currently, there is no commercialization of these products. More research is still ongoing on these composite materials as to ascertain the properties and how best to utilize these materials.

Worked examples

Example 1 — a first encounter with Geopolymer bonded wood composite

Start with the simplest possible case. Write down what Geopolymer bonded wood composite claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Geopolymer bonded wood composite before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Geopolymer bonded wood composite ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Geopolymer bonded wood composite

In research: Geopolymer bonded wood composite appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Geopolymer bonded wood composite in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Geopolymer bonded wood composite is common in secondary-school and first-year university syllabi. It links to neighbouring topics Composite materials, Engineered wood, Geopolymers, so understanding it makes those chapters shorter.
In everyday life: Look for Geopolymer bonded wood composite outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
