Abstract
A slurry composed of paper fibers, water, and cement that can then be used for a variety of construction applications is prepared. After draining the majority of the water, the slurry may be molded into blocks, sheets, or any other desired shape to be used as a construction material, or it can be sprayed onto wire shapes to form custom structures. The slurry product can be used as a mortar in conjunction with building blocks that have been made from the slurry, and it can be used as a plaster when mixed with conventional cement and sand mortar. The slurry can also be poured into forms in the same manner as concrete to form blocks for construction applications.
