KRAFTTERRA: Incorporation of paper fibers from cement sacks recycling in the production of compressed earth blocks

Abstract

This paper describes the Kraftterra mixture and production processes, as well as the performance of prisms produced with Kraftterra tested in axial and diagonal compression. The study's objective focuses on the developrnent and performance evaluation of Compressed Earth Blocks - CEBs. The inclusion of Kraft paper disperse fibers from recycled cement sacks in CEBs and mortars allows for a large increase in the walls' ability to resist to compression and diagonal compression, even after the maximum strength is reached, Furthermore, the mortar made with Kraftterra results in strong connections between blocks and produces more homogeneous building walls, with more uniform properties and high monolithicity, which induces better performance to the wall elements.
