Abstract
The present article worked with the degradability of biopolymers in membranes and plates for the production of fibers used in shallow foundations in civil construction. PLA and PHB are highly biodegradable polymers, so it had used them to test their degradability in foundation centric rigid spread footing form in reinforced concrete, since it will be used to make ecological shapes that will not need to be removed from the footing form that is made. The work was developed in three stages, the first to produce the Simulated Soil according to ASTM12-G-160-03. The second stage was the development of PLA and pure PHB and PLA and PHB plates reinforced with nanocellulose and the third step consisted in the degradability test in the simulated soil and in the real soil. The degradability control was done with the raw cotton cloth placed under a layer of simulated soil, for fifty days. After that, the cotton was taken for tensile strength test in Dynamometer, according to NBR13 11912/1991. In the test was verified that there was loss of at least 50% of tensile strength, the soil was considered appropriate for use.
