New elements are needed to contribute to the idea of not reusing the materials, but rather improving their use, the massará for example is known in the region of Teresina-PI is a connecting material, of little consistency, easily disaggregatable (friable), containing white silica pebbles and of little utilização in the region. The interlocked concrete floor presents peculiar characteristics among which are those that configure it as a floor. The work analyzes through a mechanical strength and water absorption test the capacity that the interlocked concrete floor with the addition of massará in its composition offers in relation to bear load. Two traces with massará will be tried and then specimens will be molded to obtain the results of mechanical tests and characterization of the material in the laboratory. After the tests, it was observed the possibility of using it as components in the production of interlocked laying blocks used in construction companies of Teresina - PI.
Bearing in mind that the sand used as fine aggregate in the concrete manufactured in the City of Teresina comes entirely from the Poti and Parnaíba rivers, and the massara extracted from washing the material that gives rise to the pebble found in deposits. The present work aims at the mechanical characterization of the materials that make up the concrete, using the washed massará as fine aggregate, obeying the same proportions of aggregates, water and CP IV-32RS cement for conventional concrete. The particle size tests, cone trunk reduction and axial compression of cylindrical specimens were performed. After carrying out all the procedures, it was observed that the results achieved have similar compressive strength when compared to conventional concrete dosing, proving that it is possible to use the washed massará as an alternative of fine aggregate for the production of concrete.
The residues generated by the ceramic factories, among the most varied types, represent a large part of the waste produced and the one that comes from the production of red ceramics such as tiles and bricks, reflects in great part of all the constituents of these residues. The use of tailings is becoming an increasingly common practice, often because it does not have a correct final destination and in some places, there is a shortage of natural materials. The present work aims to study the addition of residues of ceramic tiles dust in the characteristics and properties of ecological brick. A literature review on the topic was carried out, in addition to granulometric characterizations, absorption tests, thermal comfort and simple compression. After carrying out the tests, the possibility of using it as a component of the ecological brick and using it in the region of Teresina-PI was studied. The samples produced with tile powder residue showed excellent results, therefore, through this study it was possible to prove that the reuse of these residues is valid for use in civil construction.
