We currently live in a scenario of development and improvement of products offered
on the market, with the aim of increasing energy efficiency without loss of properties
and jointly reducing energy consumption and alleviating the damage caused by the
extraction of raw materials, with this basis the study to continue to seek the best
interaction between Portland cement, commonly sold in the northern region of
Brazil, and thus partially replace it with metakaolin to serve as a basis for new
applications and studies. Initially we looked for Portland Cement CP IV, designed
for highly aggressive environments, in partial replacement with metakaolin, carrying
out compatibility tests without the precipitation of any aggregates and together
checking the best spreading, thus we looked for new compounds with mixtures
ranging from 5 to 25% partial replacement, varying the proportion every 5%.
Therefore, some standards were adopted considering that the new formula is a selfcompacting matrix and thus proceed to produce test specimens and after
designating mechanical and chemical tests. Where the results were satisfactory,
30.1 Mpa against 19.1 without the addition of metakaolin, it is worth highlighting
that the values of 28 days without the addition of clay were in the range of 32 Mpa,
in addition to improving the mechanical and chemical behaviors it was able to
identify that we can reduce curing time and thus reduce construction time. With the
appropriate studies carried out, it is possible to show that a materials engineer can
introduce himself into the development of cement matrices through studies and be
able to improve even consolidated products on the market with raw materials
abundant in the region and thus designate new applications and studies on
compatibility with natural fibers
