Light Weight Cellulose Concrete


Paper is the main ingredient of LWCC and so its properties depend on paper’s microstructure. Wood fragments are thermo metrically or mechanically treated to dissolve the lignin binder and to free the cellulose fibers. Paper is then made by pressing the pulp to remove excess water. Paper is an anisotropic material and the quality and strength of its fibers differs depending on several factors. They are, the type of wood, the percentage of recycled paper, the amount of water in the pulp, the way of pulping (chemical or mechanical) and the speed of drying. Today half of the paper fiber utilized in current production comes from recovered fibers. Yet recovered fibers are inherently less strong and moving the pulp means orienting the fibres. ...more
