Abstract:
Through the search of the feasibility of usage of paperboard tubes in engineering projects it has become necessary to study deepening this material.
Following the ABNT NBR rules, some absorption tests have been carried out with unprotected and protected samples through the usage of waterproof.
Shigure Ban, the famous Japanese architect, who uses and stands for the constructions using paperboard tubes, has been used as bibliographic backup.
In the tests paperboard tubes 4 mm thick, collected from graphic offices of Itaperuna and region, have been used. The absorption results to the waterproof
unprotected samples have varied from 140.04 to 153.31 (%). To the waterproof protected samples values from 81.05 to 96.51 ( %) have been found. The
results have shown a significative difference to the absorption of the two samples tested. We can conclude that it is important to use waterproofing agents
before carrying on the project. It is also of great importance the research of varied products to the impermeabilization, since this study has focuses its
analyses in only one product. Altogether it can be said that engineering projects can be carried out totally or partially with the usage of paperboard tubes.
It is up to the engineer responsible for the project to evaluate the best usage of the material, aiming for lower cost, safety and lower environment impact
