Abstract
This is a recently developed material . It is made with re-pulped paper-fiber with a combination of Portland cement and or clay. This type of material is considered environmental friendly material. Paper-Crete is essentially a type of industrial strength paper Mache made with paper and cardboard, sand and Portland cement. It was discovered by Eric Patterson and Mike McCain.The objective of this project is to design and build a rigid, cost effective and economical inner wall of the structure or building. As builders and building owners are pressurized to use sustainable construction materials, a previously tassel building material known as paper-Crete has gained a lot of popularity amidst the recent greening up efforts. Paper-Crete is a recent technology and its use is limited to experimental and recreation use.
Introduction
To the greatest degree possible, all reasonable and proper mixing, sampling and testing procedures were followed to produce the data in this report. Since papercrete is a new material, there are no written mixing and sampling standards so in some cases it was necessary to follow common sense methods rather than prescribed procedures. Any anomalies involving sample preparation are described under Section I. Observations. The tests described in Section II were performed under the supervision of Dr. Apostolos Fafitis, with the Fulton School of Engineering at Arizona State University, in the engineering laboratory. While everything possible was done to produce valid results, the data in this report should be considered a guide to the basic properties of papercrete rather than numeric absolutes. One reason for this is the issue of homogeneity of materials. Even though we used newsprint to make our samples in order to introduce as few variables as possible, we cannot state with absolute certainty that newsprint is the same throughout the country. It is difficult to maintain homogeneity from mix to mix - never mind across the entire country or world. Stringent homogeneity may not even be an issue, but until more testing is done, it has to at least be taken into account. In the interest of absolute transparency, there are a few compressive test results, which seem anomalous to us. If you study the tables carefully, you will find some results, which do not seem to track well with others. Maybe the test results are flawed or perhaps there was a problem with the mix. We can't explain some of these results and it will take repeated tests of samples from a single mix to find out if the test was wrong or the mix varied. Formulas and methods evolve and change as we learn more, and any material can be dangerous if mixed or installed improperly.
