Abstract: Building materials are generated by the simple mixing of cellulose nanofiber (CNF) slurry with typical wood-derived material such as wood meal, optionally with mineral particulate materials, and dried. Particle boards are made with wood meal particulates; wallboards are made with wood particulates and mineral particulates; paints are made with pigment particulates; and cement is made with aggregate particulates. The particle board samples were tested for fracture toughness. The fracture toughness was found to be from 20% higher up to ten times higher than the typical value for similar board, depending on the formulation. For cases of 20% by weight cellulose nanofibers and 80% wood, the fracture toughness was more than double that of typical particle board. The process sequesters carbon and oxygen into the building product for its lifespan—typically decades—and avoid releasing CO2 into the atmosphere.

Abstract: A quality assurance system for mixing a slurry comprising at least water or other liquid and at least one flowable wet or dry mass, such as cement, sand or other suitable component, has computerized control over the loading of ingredients and has an accurate and broadly variable speed control of the loading of the ingredients. The mixing chamber has scales that provide a signal indicating the current weight of an ingredient in the mixing chamber.

The broadly variable control of the loading rate of the ingredients allows more accurate control of the final weight of each ingredient added. Further, a damping period allows system vibrations to dissipate, allowing highly accurate weights to be measured.
