Moisture Buffer Value of Composite Material Made of Clay-Sand Plaster and Wastepaper
Moisture Buffer Value of Composite Material Made of Clay-Sand Plaster and Wastepaper

Summary/Abstract: The scope of the Nordtest method is to evaluate the moisture buffer value (MBV) for materials exposed to indoor air. The test is intended to simulate daily variations with relative humidity (RH) of 75% during 8 hours and 33% during 16 hours. The specimen made according to a recipe contains the following: waste paper, glue, clay plaster mixture and water. Eleven paper plaster mixtures with different percentages were used. Test results showed that a large percentage of paper in the plaster increases the MBV. An impressive result, which needs to be studied further, was that the MBV was the highest in the mixture that consisted of 80% paper.
