This study concerns the development and analysis of the Kraftterra composite – raw earth stabilized
with disperse fibers made with kraft paper from recycled cement sacks – for the production of CEBs
and mortar for masonry infill elements. Its main goal is to define the behavior of small walls (prisms)
of Kraftterra in relation to diagonal compression. The tests show that the prisms produced with
Kraftterra CEBs and mortar show excellent bond strength between block and mortar. All the prisms
tested presented fissure lines very close to the normal load line and the fissures occurred in the blocks
and in the mortar in similar manner, without separation between these elements. The mortar produced
with Kraftterra results in strong bonds between blocks and produces homogeneous construction
elements with uniform performance, that is, with high monolithicity
