2014
We present a novel method of manufacturing rigid and robust short natural fiber preforms using a papermaking process. Bacterial cellulose acts simultaneously as the binder for the loose fibers and provides rigidity to the fiber preforms. These preforms can be infused with a resin to produce truly green hierarchical composites.

FAQs
Performance begins with the rate at which magnesium oxide reacts after water is introduced. Reactive MgO hydrates more readily, while particle size also affects the available surface for reaction. These characteristics influence setting behavior and the development of the hardened matrix. Selecting suitable reactivity and fineness therefore helps engineers adjust performance for a particular formulation or application.
Several reactions may create binding phases, depending on the formulation. Hydration produces magnesium hydroxide, while mixtures containing magnesium salts or phosphates can form additional phases that strengthen and densify the matrix. Exposure to carbon dioxide provides another pathway, allowing carbon dioxide to participate in binding reactions. The chosen chemistry determines how the material develops strength and density.
Mixture composition and curing conditions control which reactions proceed and how the resulting matrix develops. They can affect setting behavior, dimensional stability, strength, and densification. Exposure environment is also important because carbon dioxide may participate in binding in some formulations. Engineers must therefore consider the complete combination of ingredients and curing or exposure conditions rather than MgO alone.
Preparation starts by combining MgO with water, then incorporating any formulation-specific magnesium salts, phosphates, or other components needed for the intended binding pathway. The mixture is placed under selected curing conditions so hydration or other reactions can proceed. Controlling MgO reactivity, particle size, composition, and exposure environment provides the main means of tailoring setting and matrix development.
MgO binders can support several engineering applications, including construction materials, waste solidification, and repair systems. In construction, their tunable setting behavior and dimensional stability may be valuable. Waste solidification uses the binding matrix to help form a denser stabilized material, while repair systems can benefit from formulations adjusted for their required hardening and exposure conditions.
In suitable formulations, carbon dioxide can react with MgO-derived materials and contribute to the formation of binding phases. This creates potential for carbon dioxide uptake while strengthening or densifying the matrix. The outcome depends on the formulation and exposure environment, so carbon dioxide uptake should be treated as a condition-dependent performance feature rather than an automatic property of every MgO binder.
