Introduction. Floods and weather changes
are affecting the homes of the people who
live in open shores. The idea of the term
amphibious houses is to provide a solution
to the se people´s housing, preventing the
loss of the houses in the floods. Objective.
To evaluate the best mixture of cement
and aggregates to develop a floating
structure (slab) intended to be the base for
floating houses. Methodology. A standard
commercial mixture was taken as a base
and other two mixtures were made in
order to compare. In the mixture cement,
common sand and 3/8 crushed were used.
Three treatments with three replicas for
each one were performed, completing nine
tests. The experimental design used was a
unifactorial design. Results. If a highly firm
slab is aimed to be built, the mixture from
proportion 1 is recommended. Proportion
3 is recommended for the opposite.
Conclusion. If a formula to develop a resistant
and stable slab is required, treatment 3 is
recommended. It has 14.28% of cement,
28.57% of sand and 57.14 of crushed.
